What happens if I connect the car battery wrong?
Connecting them the wrong way may cause damage onto the battery you want to charge. For one, this causes a reverse in the polarity of the car battery. it might even cause the battery to explode in some cases.
What happens if you hook up the battery to the 2nd post?
A big ol’ spark warned me off just as I touched the 2nd cable to the 2nd post. Nothing was harmed, not even the rectifier. Now, these guys are probably correct, you have let all the smoke out of the rectifier, and it won’t work without it’s smoke, and it’s almost impossible to get all the smoke back in there.
What should I do if my battery isn’t hooked up?
If so, and if it’s working normally, then you’re done…the rectifer is fine. Tach won’t work with a blown rectifier. Next, if you have no tach, measure the voltage across the battery with engine off. Start the engine and measure the battery voltage again. If the voltage is higher with the engine running, then you are good to go.
Can a blown rectifier cause the battery to not work?
Tach won’t work with a blown rectifier. Next, if you have no tach, measure the voltage across the battery with engine off. Start the engine and measure the battery voltage again. If the voltage is higher with the engine running, then you are good to go. Click to expand…
Can a battery be broken by connecting the wrong way?
Almost all consumer electronics have protection in place to prevent any damage when connecting the battery backwards. Companies know they can’t trust consumer to put the batteries in the correct orientation and it is usually cheaper for them to add the protection then it is to deal with support calls and returns.
What happens when a car battery is put in backwards?
Car Battery put in Backwards. Car designers realize the battery will be reverse installed sometimes by accident, so they take measures to limit the damage when it happens. The most likely things that are damaged in this situation are the fuses and fusible links, and sometimes the alternator. All are easily replaced.
Can a battery be connected in parallel to increase power?
There are however devices in which batteries are connected in parallel ( + to + and – to – ). This is to increase power rather than voltage. A typical case is a so-called “power bank” in which up to 6 18650 batteries may be in parallel. I have some Chinese samples and none of them has a protection of any kind.
What happens if you reverse both the batteries?
If you reverse both batteries the result may be worse: most likely the device will be damaged, esp. if it’s electronic. The batteries may survive without too much damage unless the reversal causes a short circuit. “esp. if it’s electronic” what else can you can you power batteries with that aren’t electronic? – Dean Dec 12 ’10 at 13:59
