years back I installed vdo gauges, but used a common ground for the lights and for power which made the gauges give incorrect readings dependent on the dimmer position when you turned on the lights.
I changed the power ground from a brown/white wire to a brown wire which got rid of the strangeness if you turned on the dash lights. A few seconds later the dash lights went out. If i flip the dimmer to the first/second position the radio lights dim, but can not be adjusted. Lighting to the OBC, lighter and dash cut out. Sidemarkers, all the lights on the rear, hazards, etc are fine. AC switch doesn't light up at all (with parking lights on and off) hazard switch lights up, defroster lights up.
Fuse at pin 23 is fine, but i have no power at fuse 23's location. All the other lights on that fuse light up just fine. Any suggestions on where to start for troubleshooting? 1990 325is
