No Dash Lights - Rheostat?

[Travis Blake]

 I have finally gotten back to dealing with the electrical issues with the 74 Challenger. It is a new repro harness.  I have been told the rheostat is likely the problem with no dash lights. It has a 3 wire plug and I need to know which wire feeds the rheostat as I plan to "jump" it to get lights.

 I used a jumper wire to check the dash lights themselves and they work. Could the light switch be a problem not supplying power to the rheostat ? Thanks for any help.

My dash light dimmer didn't work either so we just bypassed it from the light switch. The dash lights are now on full when they are on. It's not too bright, just right for me.

You can also send your switch to JS Restorations.  Jim will restore the switch and get it working like new.

Ok cool,    Did you jump it from post to post on the rheostat or did you jump it from the light switch to a post on the rheostat ?

Do they have a website?

It was a few years ago but I think we jumped from the light switch. Not sure if we touched the rheostat at all. Might have gone direct to the wire feeding the lights. Can't remember for sure.

If you jump the terminals with the wire colors:  Black/yellow and   Black ----    To the tan.    .....With the dimmer switch  disconnected  this will bring on you dash lights on when headlight switch is turned on.

If your headlight switch is not the culprit. Also.

Check yourdash light fuse also  should be fuse 5.      5 amp



Also when your headlights are on the.   The terminal with the black  black/yel. Should have 12vdc   From that terminal to body ground. If you do your  headlight switch is good
