Im hunting down some electrical issues. But we can do one thing at a time.
Like i mentioned, btn 60amp fuse reads .14 draw. I disconnected every fuse one by one and it never dropped but the funny past is that when i press the brake pedal in and moved the tail like switch it goes to 0.0 draw. Idk what this means.. i diconnected the two connector of the brake pedal switch to see if draw woukd drop and it stil read .14 draw.

 

It does drop to 0 when stop fuse is removed.
It stays at .14 draw when both tail light 6pin connectors are disconnected.
It drops to 0 draw when brake pedal is pushed and brake lights work.

 

There's a lot tied into the brake light circuit depending on what year and trim level your car is. I'd start at the CPU and go from there... this is from the S4 FSM.

Edit: wait... zero draw when the brake pedal is pushed? Uhhh... what?

 

I have been suspecting the cpu. Not sure how to start on that.
yes, draw disappears when i press the brake pedal.

 

I can hear the relay clicking inside that chassi cpu. Was checking draw @ stop fuse and noticed the clicking.

 

Something changed. Now i dont have the intetior door lights and chime/beeping.

Kept hunting issues and found my meter fuse to have a short. Good from fuse to battery. But when i check the harness side of the fuse slot ,with fuse removed, it reads .74 volts. Wtf. now everything associated with black yellow wire is out. Including gauge cluster functions and everywhere the black yellow goes which im finding is many places.. where to start..

Where does this black yellow wire branch of. My haltech was getting its switch 12v from yhe black yellow wire at the blower motor 8pin connector.
