My dash lights went out when someone fried my battery by putting cables on backwards. Don't know exactly what happened. So don't know how to fix. Help please.


Many of today's cars have more electronics than mechanical items anymore. Rather than the old point-to-point wiring that was the norm, now the cars use computerized serial data buses to transmit control signals and the like. Hooking the battery of backward is a big no-no on these systems as it fries everything since the protection circuits aren't designed to ward off such errors. If you are having multiple electrical issues after a battery "backward boo-boo", you're best taking the car to an auto electric specialist and explaining what happened. They can assess the level of damage and can tell you if it may be cheaper to replace the car than repair it......

I had to replace my main 120amp fuse. Is there any other fuses that would blow if you crossed battery cables.


worse case scenario: you could have fried the ecu / ecm

anything electrical is effected; had a neighbor's car whole front end wiring to his headlight system got fried/melted together
do you have access to an obd2 scanner and plug it in to check?

in hindsight, this is one of the reasons why calling AAA for a jumpbox is better than having someone hook up jumper cables incorrectly ~ most also will connect the cables directly to the dead car's battery terminals when you're really supposed to connect it to "engine ground"

once you gave it a look over all the electrical wiring and fuses, time bo bite the bullet and take it to the shop ~ sadly

What happens when you hook a care battery up backwards?


Hello Glen, Bad bad things can happen when you hook up a car battery backwards. If your car has a high quality electrical system it might only blow out one or two main fuses. If not, it can cause havoc on the wiring system and burn out the alternator, computer, sensors, modules, and stereo system to name a few.

Sorry to say, sounds as if you had cables hooked up backwards, or possibly just had very poor connection between battery and battery cable terminal. If you may have had jumper cables connected backwards, you may have fried some electrical component. Get someone to read the codes which are making the check engine light come on, and perhaps this will give a clue as to what component is blown. Could have damaged anything from a small sensor to the main computer, in which case I would check with salvage yard for a used unit. The main computer is quite pricey.

When i connect the battery cables the it fires off hot


It sounds like you either have a dead short or the starter is stuck in the engaged position, whitch if it is stuck, it will cause a spark when trying to connect and if it was previously in that condition, it would also run your battery down and possibly fry something else.If it seems to act like the starter is stuck, it could also be a locked up engine but I do not know the whole scenario. If your talking jumper cables, not to be smart, they could be backwards. I also ran into one incident with a blemished battery that the top of the battery was labeled wrong and the posts in the battery were backward which caused extensive damage which the battery mfg. covered.

I changed the battery on my 07 cobolt... it sparked and now my radio and factory alarm dont work


if you connected the battery properly(red to positive, black to negative) there should be no problem even if the connections arced. if you hooked it up backwards you may have fried all the electrical in the car. does anything electrical work? does the car run?

I accidentally hooked up jumper cables backwards when I was trying to jump start my 97 Ford Escort. Needless to say, it was not good. It started to spark and caught on fire. I was eventually able to get it...


I bet you saw some dramatic sparks when you hooked the jumpers up backwards!
The good news is that if your ignition switch was turned to the "off" position when this happened, the fix may be simpler and cheaper than you think. This car has one or more "fusible links" in its primary wiring. They may look like a thick piece of wire, but they act as super-fuses in the the case of large-scale power shorts and the like. Fusible links are typically in-line, so you won't see them in either your under-hood or under-dash fuse boxes. If you're lucky, you blew a fusible link right off the bat, saving the rest of your electrical system from serious harm.
If your ignition was turned to the "on" position when the battery was hooked up backwards, you have a more serious risk that you damaged your on-board computer. However, even if your computer were fried, your dome light, your hazard blinkers, and probably your headlights and turn signals (different circuit than the hazard lights, believe it or not, even though it's to the same bulbs) would continue to operate.
I'm going to recommend that you should check for one or more blown fusible links. Good luck!

Changed the starter and than the battery blew up.. Now when i hook up the battery it saparks{the wire spark} what could the problem bee....PLEASE HELP


Hi and welcome to FixYa!

There can be a wounded wire somewhere so I strongly suggest that you check the electrical wirings. The spark is normal but to be sure please check the wirings.

Hope this helps and thank you for using FixYa! Have a good one!
