My electrical system on my custom painted gold 1986 BMW 535i .
- I just had installed a new ECU, and now my while the car is sitting,
my battery drains down, and my automatic locks malfunction when I put
the key in to open the car up. They open and close and my dome
lights do this also, if I put them in use. It seems obviously like a
short somewhere, but where will I start to rectify this situation, and
how costly do you think it will be the revamp the electrical system?
- Hi, it could just be your battery is low on charge or on it's way out.
The same thing happened to mine. The door locks wouldn't lock properly
and my electric aerial would go up on accessories, then start going
down on start. This happened for months until I got a new battery. Now
everything works as it should, even the lights are brighter!
