Still got MAJOR electrical issues. 850

I could very well be wrong, but I believe the lights on when you press brake is a ground issue. I'm thinking your pedal pressing pushes some wire that is now exposed over to the light circuit.

Here's what I'd do:
Hopefully you have a multimeter, if not you can probably just get by with a multimeter..

I'd first hook up the Ohmmeter to the battery positive and negative terminals without pressing the pedal. It should read infinity or OL or whatever that means there's not a complete circuit . Then press down the brake pedal, You should get a reading, if I had to guess it would be somewhere around 100-200 Ohms, though could easily be more.

Assuming this plays out as I've described you get to have a little fun pulling fuses and taking readings when you press the pedal. I'd start with fuses related to cabin items radio/fan and move outward from there. I'd probably try them all just because i'm not doing it twice...

Eventually you should have a fuse (or two) that when pulled make the car read the same with both pedal pressed and depressed.

From there you've narrowed the circuit down to whats causing the short. Hopefully its one of the easy ones with only a few wires to trace. IIRC you did the dash removal so you should be able to confine yourself to wires in the dash/firewall area.



If you end up trying this and you get stuck/something different from what I'm guessing will happen/ whatever post and I'll try to help.


Parting questions: Are there any wires that are touched with the mechanical action of you pressing the brake?

Is the only thing acting up now that when you press the brake the lights go on? IIRC the brake lights would illuminate but since the key is off they should be off. That might mean that that circuit is suspect. Perhaps something just got caught?

And finally, when you had the keys in and you pushed the brake were the same lights going on?
