Hooked up starter ding diagrams!!!

Contact Author Source Battery problems can strike without warning, the unsuspecting owner fearing that something terrible happened to their vehicle overnight and now it won’t start at all. More often than not though, the vehicle is completely fine other than a battery that’s acting up. Car batteries are probably the most volatile component in the car, and it doesn’t take much for them to go bad. They only have a shelf life of a few years, and they’ll die quicker because of things like disuse, corrosion, and faulty connections. It takes a very large amount of power to turn over an engine and start a car. The batteries are designed to give a big push of power and voltage for a short period of time. If you’re not sure what your problem is though, make sure you read through all of the possible problems, and go to my other articles on solenoid problems and alternator problems to make sure you can rule those out too.

Hook battery cables up back words truck will not crank

Automotive batteries are designed to produce the high electrical current required to start the engine. This routine procedure can become dangerous if the jumper cables are connected improperly — if the positive terminal on each battery is mistakenly connected to the negative terminal on the other battery. Damage will result from very high current flow, and possibly from incorrect polarity on the “dead battery” vehicle.

Jumper cables are not designed to carry the huge surge of electrical current, and will quickly heat up to very high temperatures. This can melt the insulation on the cables and potentially expose people to direct contact with the electrical cables.

Making the wrong connections can cause sparks, and improper polarity also could damage either the donor or recipient vehicle. Use care when jump-starting a car. You are running late. To make matters worse, your car won’t start. What can you do? No-starts fall into two basic categories: The engine will not crank or cranks slowly 2.

The engine cranks, but does not run No or low cranks Dead battery A dead battery is the No. If the battery is weak, but not totally dead, the starter may turn slowly. As the voltage drops further, the sound may become a staccato K-K-K. When the battery voltage drops even further, there will be no sound.


May 31, , This is completely false! If you hook the cables up incorrectly, it can and will fry your electrical system though. Our batteries have a 12V potential and can supply CCA cold cranking amps.

Connecting the jumper cables the wrong way might actually damage your vehicle. If your battery is running low (that’s why you can’t start) then you have less voltage across it’s nodes. When you connect another battery with the exchanged nodes, the current will flow out of your battery (since it’s voltage is lower) and damage the battery.

Exactly how the diodes will react to the excessive current flow is hard to predict. Sometimes they blow apart into an open circuit or a very high resistance, sometimes they melt together into a short circuit with a varying amount of resistance but generally quite low. In the course of working with solid state rectifiers since I was about nine years old, I have seen many different failures as a result of excessive current. I don’t think you can predict the results.

At least I have not seen pattern. The best result would be to hope for an open circuit, as this will tend to stop the current flow.

Accidentally reversed polarity when jumping car, need to know what damage to look for

What Is The Cause Yesterday morning, my car, a Toyota Chaser, would not start because it was very cold outside and I borrowed a fully-charged warm battery from my friend next door to start the car. It was very cold outside which made me hurry with connection etc and I found myself connecting the battery in reverse. I noticed too late that the battery from my friend was a bit different from mine.

Nov 07,  · When you hook jumper cables backward neither battery starts producing H2 because they’re both DIScharging into each other. But the two batteries form a circular current path in series, and dump energy into the jumper cables and each other at a .

It might seem like your battery is dead, but if the lights and electrical systems are still running, your battery might just need a jump start. Follow these steps to give your battery a boost and get back on the road. You’ll need a set of jumper cables and another vehicle with a charged battery. You can find cables in auto parts stores, at gas stations or just about anywhere you buy car parts.

Park the car that needs to be jump-started next to a car with a good battery. Park the car with the good battery next to the car with the dead battery. Pull the car close enough so that the cables will easily reach from the battery of one car to the battery of the other. Shut off both engines and prop open the hoods or trunks, depending on where the batteries are located within the vehicles. Each battery has two metal terminals.

There are also positive and negative cables in the jumper cable set. Never connect the red cable to the negative battery terminal or a vehicle with a dead battery. Identify a metal ground Identify a metal ground within the vehicle with the dead battery. You can use the metal frame of the vehicle.

What happens when you hook up car battery cables wrong?

Which to Connect First in Car Maintenance on October 7, Improperly connecting a car battery cable when jump starting your car can cause serious damage to your car, the car supplying the jump and possibly cause severe injuries from burns to you and the helpful motorist supplying the jump. The charge and discharge cycle of a battery causes hydrogen gases to build up. These gases escape through vented cell caps and can accumulate around the battery.

If you connect the jumper cables incorrectly, you can create a much large spark than normal and this spark can ignite these gases and cause an explosion. Connect Positive Cables First Connect one positive or red cable end to the positive or red terminal on the dead battery.

Hooking up jumper cables in the backwards has the potential to cause an explosion. The reaction occurs if hydrogen gas builds up around the battery and a spark ignites the gas. The correct way to apply jumper cables is to attach the red end to the positive terminal of the dead battery first, then the other red end is attached to the positive terminal of the charger battery.

It’s not a review, just a text on what to look for on jumper cables. If this text breaches the rules, you can spank me. And people please don’t copy my text and publish it one you name, it’s rude and my text is full of spelling errors. Every car driver will eventually end up with a flat battery. A bad battery, leaving the lights on, not having used the car for a while, etc. A problem which can be solved with jumper cables. But jumper cables are not always as straight forward as we think.

Thick cables are usually better. A thicker cables generally means a higher capacity. However thickness of the cables can hide a few facts. While jumper cables used to be all copper, there are now three kind of materials used for jumper cables; solid copper, solid aluminum, and copper coated aluminum cables. This means aluminum cables appear to be thicker or are just as thick, but have less capacity.

Well the battery was down in my jeep 5. Now on the jeep it turns over ok but wont fire. All of my gages wont move and my radio doesnt work.

Jun 17,  · You probably just burned the fusible links. If your stereo was on you might have fried it. I recently learned that there is an orange relay with a diode inside that protects the ECU from reverse-voltage if the battery or jumper cables are hooked up wrong.

Many computer users perform their own hardware upgrades, and a distressing number of these result in insufficient damage to the system. Destroying your own computer is every user’s right and is the pattern of behaviour expected by the manufacturers and, especially, repair personnel, whose very livelihood is put in peril by those users who perversely persist in correctly upgrading their equipment.

This article will explain to you, the user, the most common ways by which you can cause your computer to cease to function. Follow the instructions carefully and you will shortly find yourself making appropriate contributions to the all-important service sector. Keep your hair on, people Yes, this article by Sander Sassen at Hardware Analysis is a bit similar to the page you’re looking at. No, it’s not a rip-off. Great minds just think alike. Thank you to everyone who wrote to me expressing their concern, and to everyone who wrote to Sander and called him rude names.

The boy’s going to be in therapy forever. First, it is essential to be incorrectly prepared. When opening the case of your computer, you will probably be presented with a number of hexagonal head Phillips-slotted screws.

What would happen is you cross the wires when jumping a car?

She then let some other teenage boy at school try to jump the car off. This idiot hooked the jumper cables up backward and blew alot of fuses in the car. Took awhile for me to figure this out and why the car wouldn’t start. Anyway I replaced all the fuses and now have problems. For one thing, now the radio won’t come on and the fuse is fine.

The clock keeps going back to 1:

Oct 03,  · Well first of all if you hook up jumper cables backwards you will get a big spark off the battery. telling you it is something wrong. and you need to check your connections. For this not to happen look at your battery before hooking up the cables. There it a + for positive which is red and a – for negative which is : Resolved.

I learned to jump a car by watching my uncle several times, and he used to be an electrical engineer. He was always really adamant about grounding it far from the battery with the impression that terrible things would happen otherwise. I guess I’ve just never dealt with anyone else so the idea of using the battery was like telling me to stick a fork in an electrical socket. I’ll stick with the proper directions, but at least I know what he was talking about now.

This is why most people clamp onto the frame for the last connection which should be ground on the donor car. That’ll also be the first connection you remove, so again, no sparks near the battery. You still need to be aware of the potential for sparks. I’ve seen the accident report on an actual battery explosion, though it was a stationary plant start battery. Short version is a plate was cracked internally, the operator thought it was flat and boost charged it; when that didn’t work they attempted to jump start it.

Because of the cracked plate and overcharging, the battery was basically full of hydrogen and oxygen; the pressure build up had caused the microcellular vent to lift out of its seat; and the spark from attempting to jump start it flashed back past the displaced vent, into the battery casing, and the battery exploded. Which helps explains why battery explosions today are a lot rarer than they used to be.

That gives a nice path for any flash to travel back into the battery and cause an explosion; additionally, it was common for people to check the electrolyte level and leave the caps off before jump starting. Instead of vent caps, modern sealed or “maintenance-free” batteries typically have a semi-porous microcellular vent which provides no flash path back into the battery.

Add a personal message: Sending your article Your article has been sent. Sears has an impressive, if somewhat ludicrous, video in its automotive centers showing a DieHard battery getting blasted by a high-powered rifle. Back then, batteries often leaked, got caked with corrosion, and needed to be opened and filled with extra water about once a year.

RAY: By the way, they now sell “idiot-proof” jumper cables that won’t operate if you hook them up incorrectly. Go out and buy two pairs. King Features Syndicate.

Originally Posted by saajlexus But once you plug both terminals on both cars in, dont you turn the helper car on? You would want to hook up the jumper cables between the cars, let the good car run for a few minutes to try to get a charge in the bad battery, and then turn the good car off before cranking the dead car. Now, it is understood that if the battery is extremely low this may not work and the good car may need to be running to get some extra current.

If that is needed then I would keep a high idle 2K rpms or more while the dead car is trying to crank. Personally I’ve never had a problem running the good car while cranking the other, but the risk is there. If the dead car is able to start then I would have it immediately taken to an auto store to have it checked out and see if it can be charged, otherwise you might end up replacing the alternator if your driving around on a bad battery.

Never disconnect the battery from the alternator either while car’s running , whether it is in good or poor condition. Oh, and although obvious, never jump a battery that is cracked, leaking, or shows signs of damage.

The problem with hooking up the jumper cables backward is that ANY electronic component in the vehicle is at risk. This could mean the throttle body (TB). It could be an alternator.

My symptoms are no power to speak of below rpm. At that point turbo boost occurs and power comes up, though no where near what it should be. The engine revs smoothly but runs out of steam before rpm. I’m left to decide if the problem is the AMM or the O2 sensor. If your B FT throws oil around like mine, the throttle body can easily get crudded up and cause problems exactly as you described. All these were fine, just a dirty throttle body caused the problem. Use a small flat-bladed screwdriver to loosen the little locking tab on the end of the lower ball-and-socket.

One right-hand thread, the other left-hand. The gasket on my car lifted right off with no fuss, but if you have to scrape be sure to use a plastic or wood scraper so as not to damage the aluminum facing. Swab it out with clean rags and lots of good quality carb cleaner.
