What happens if you hook a battery up the wrong way?

What happens if you hook a battery up the wrong way?

Depending on how long it was connected the wrong way the battery may survive and just need charging but the chances are it needs replacing. You would have also most certainly blown some fuses, look for some big ‘mega’ fuses connected directly to the positive cable. Not the answer you’re looking for?

Can a reverse polarity fuse blow a fuse?

My father-in-law recently bought a Hyundai Genesis that has an internal switch preventing reverse polarity hookups from damaging the electronics. Hopefully more manufacturers will do this to prevent what is a very common mistake. You can see into these big fuses and they don’t appear blown.

What happens when you hook up jumper cables wrong?

The next day I got a friend to help me jump it. He put the cables on wrong and when we put them on the right way, the car wouldn’t start. I had it towed to mechanic. They said they didn’t know exactly what was damaged but the ECM was probably blown.

Can a Camry battery be hooked up wrong?

It is also on a gen 6 Camry 2009 le. I did my biggest screw up today I went to hook up a new battery and didn’t notice the terminals were opposite of the old one.

What happens when you hook up a car battery backwards?

When they put installed the battery, they hooked it up backwards and blew the main fuse. When the main fuse was replaced and I was driving off I noticed that the charging light was on, and the radio/clock was not working. Taking it back, they confirmed that the alternator was dead and replaced it (with me paying for it).

What happens when you connect a jumper cable backwards?

Connecting the jumper cables backwards will often result in one or more blown fuses. The affected circuit will not function correctly until the blown fuse is replaced. Reversing the battery cables creates a surge of electrical current that can easily damage the battery.

What happens when you reverse a battery cable?

Reversing the battery cables creates a surge of electrical current that can easily damage the battery. When you reverse the polarity of the jumper cables, you create a drastic increase in the amount of electrical current that runs through them.

What happens if you connect a jumper cable to a dead battery?

Connecting the jumper cable to the negative terminal of the dead battery can create sparks and potentially cause an explosion. You should never attempt to jumpstart a frozen battery, as doing so can cause it to explode. Remove the dead battery, bring it inside, and allow it to thaw before attempting to jumpstart the vehicle.
