New gremlin,

I noticed the other day that when I shut down that I could see my instrument cluster lights were still on (very dim), but would go out when I let the brake pedal go...head lamp switch off of course. Further poking revealed that all park lights were also coming on very dimly as well when the brake was depressed (ie plate lights, tail lights rear window light). If you press the brake pedal when the door is open...all of the above plus the dinger for the door open/lights on warning. Also when I turn the hazard lights on same as before but on and off intermittently with the blinkers. Measured voltage at 9VDC at left front park light.

Any ideas? Sounds like a diode problem to me but I don't know where to get proper wiring diagrams.

Any advise appreciated.
 
Sounds like a missing ground, with the brake lights finding it through the instrument cluster.
