Has anyone seen this?...1974 Warrior panel lights don't come on, and
when I turn the rheostat past a certain point (almost full bright) the
panel lights breaker pops. I'm thinking it's the power transistor, at
least that's what I'm going to try first (along with cleaning the
rheostat) since it's the cheapest thing to do.

My bets on a genuine short circuit in the lights, maybe
a bad bulb. There is not enough current to pop the breaker
before the setting is nearly full.
