I was trying to install an aftermarket headunit and lo and behold I did not disconnect the car battery before I started. I already realize my boneheaded mistake.
Anyways, I'm having these electrical issues:
- If I reinstall my stock headunit, it does not power on when I turn the engine on
- When the engine's off, my power door locks do not work
- When the engine's off, my remote door locks do not work
- Whenever I turn my engine on, my trip mileage counter resets.
Other electrical systems such as lights and blinkers work fine when the engine is off. And when the engine is on, AC, power locks, power windows, lights, etc all work fine as well.
My friend who is familiar with aftermarket installation checked my fuse box and did not see anything getting wrong. He says that most likely I short circuited something, but it will be a pain to figure out where. He says I'll need to get a volt meter find where there's a closed circuit, but I don't even know where to start.
Does anyone know what I can do in this situation?
If all else fails, I'll just have to reinstall the factory headunit and bring my car in to a Honda dealership. My car is due for a 60,000 mile maintenance anyways, but I know they will charge an arm and a leg to fix my electrical problems.
