Question Lights out !

On the way to work at 5:30 this morning my 1969 C-10 lost it's headlights . I hit the dimmer switch a couple times and they came back on . May have bumped the dimmer switch with my foot causing the lights to go out . What do y'all think ? I've a book somewhere , wonder how hard it is to change the dimmer switch ? THANKS !

Re: Lights out !

Couple of phillips screws and a plug in. Sounds like that is the culprit...

Re: Lights out !

that is a normal indication that dimmer switch is going bad// get new dimmer at autoparts store(very cheap) and inspect and clean the connections prior to hooking up new dimmer

Re: Lights out !

I'd clean up the connections before throwing a new switch at it.

Those are pretty tough switches and the connection there is notorious for getting green and furry.

Re: Lights out !

i agree with mrein3 that connection must be clean and also i believe it grounds on the cab floor and if it gets loose it will do the same thing

Re: Lights out !

there is no ground on the switch, and I would blame the switch before the connection... but the connection is easy enough to check though.
Dirt cheap part too.

Now order from NAPA a handfull of part number 725147. This part is the little brass colored insert in the plug you plug into the side of the dimmer switch.
You can work the insert out of the plug, shorten the wire back to good wire, clamp on the new insert, put it back in the plug, and go another 40 years.
Or keep it greased up with your dielectric grease and never worry about it again.

I keep a bunch of these in my electric kit because just about every connector on my truck and on my Chevelles use this same style of connection.

The part number for the male version is 725145.

Re: Lights out !

They don't get salt on the roads, or even much snow on the roads in South Carolina. In Minnesota the terminals corrode from all that salt and slush.
