headlight switch-no lights

[supertweet]

seems the switch is not working, power at rear post, nothing anywhere else, have an old spare, can i bench test it, should i install it or hit the old one with electrical cleaner or carefully disassemble? thanks, Dave.

Spray the one in the truck with contact cleaner and push it in and out a bunch.

o.k. thanks ill try that, took power wire off of the circuit breaker, small metal rectangular shaped, "aerovox-self closing 30 amp" - should i try to replace or can i bench test-will spray switch first... thanks again, Dave.

Push the dimmer switch on off /on off too.

use a multi-meter to check for continuity between the circuit breaker posts...probably wouldn't hurt to pry the tabs back carefully on the drawer switch and clean the contacts, then apply dielectric grease to get the switch back in working order.

ran power direct to switch and it worked fine, so it's this circuit breaker, think i can just pick one up tomorrow at napa or is there a repair? won't operate with direct power, (may cause it to fry?), will spray and clean up switch while we're under there, what a relief the 64 yr old switch works, what quality eh! thx, Dave.

Pick up a new one. You don't want one to stick closed. Defeats the purpose of having it there.

My local Auto/Electric Shop used their bead blast cabinet. In just a minute or two it looked brand new. After that applying dielectric grease wouldn't be a bad idea. Probably no need to search for a new switch without trying your best.
