Need some more electrical help

[Mark1968]

Seems I`ve lost power to the fuse that powers the dash lights, interior lights and running lights. Only one fuse on the block is not powered.

I need to know what feeds this fuse, the diagrams I have are not clear, it looks like power passes through the headlight switch before going to the fuse but I`m not so sure this is right.


Does anyone have a complete wiring diagram for a 79 chevy they would be willing to post up?

Here ya go, I believe all of the power passes thru the fuse block before it continues to and equipment or switches.

the fuse block powers everything through the internal connections.you may need a new fuseblock if its burnt.should be one main power coming in from the battery,mine is purple i believe to the keyswitch then to the fuseblock.there is a pink constant that powers the other circuits such as lights and other accessories that need constant power.
