Solid state components resist in one direction and conduct better in the other direction.
You have fried some transistors and chips.
The starter and solenoid system handles more current than solid state electronics can handle. It's a simple system of coils and relays. It is not polarized and does not care about negative and positive. It hasn't changed since 1905.
You have shorted out a lot of electroncs. If you're lucky then fuses blew when the current ran backwards. There are lot of microprocessors to replace.
Sorry.
What else can I help you with?

Check the fuses. By hooking it up backwards, you may have blown many fuses, and/or completely damaged the vehicle wiring system, and/or shorted out the starter motor.

What happens if you connect the ground wire to the terminal and the red wire to the - terminal on the car battery ie connect the battery backwards but did not start the car?
once a battery is connected even if the key is not in the ignition, there is always power at certain points in your car. Connecting a battery backwards will not start your car, but it can and will fry the wires to your starter.
Aerostar just clicks when you turn the key and will not start?
check the battery,check the starter, see if their both good. It's the battery, if all it does is click. The clicking is the starter trying to start but not having enough electricity.
How can you fix your truck that will start but will not fire after hooking battery cables wrong?
You probably fried all the electronics. Take it to a trusted mechanic to diagnose it.
Why doesn't 2001 kia sportage keep battery charged?
I would start by checking the alternator yourself or take it and have it checked. If you had'nt had any battery issuses like hooking battery up wrong It is prob. your alternator.
Battery was hooked up backwards in 1987 BMW 325 now car wont start?
You have some serious problems. Hooking up a battery backwards plays hell with the electronics. If you really want to keep the car you will probably have to replace a lot if not all the electronic control devices that manage your engine.
My gf hooked the battery up backwards in her 1981 Chevy blazer and i hooked it up correctly and now it wont start it don't click or anything what could be the problem?
