Random dim lights

More on the dash lights. They are a bit of a trick. There are two sources of power for the headlight switch One, UNfused, comes off the ammeter circuit and powers ONLY the headlights. Switch has a built in breaker

Tail, park, and dash light power comes from the tail light circuit fuse, so that circuit must be working for dash lights to work

The light switch feeds dash light power in, through, and out of the dash light control rheostat (twist the knob) and then out on TAN TO THE fuse box. This goes to the small INST fuse at one end of the box, then out to all dimmer controlled dash lights on orange wiring. If the dimmer control is damaged or dirty, you will have fluttering dash lights. Start by vigorously twist ing the knob back and forth about a dozen times.

Also check for corrosion/ looseness at the INST fuse, and loose wiring at the back of the fuse box.
