86 bronco 2 engine dies when dimmer switch is pulled back.
1986 bronco 2 runs great at idle. When dimmer switch is pulled, even with lights off, it kills the engine. Same when under load, in R or D, and your turn the wheel. Started with ECM, no luck. Checked grounds, seem tight and good. ordered a turn signal switch to try next but that doesn't explain the power steering killing the engine. Wire short in column? I looked but didn't see anything.
