Trying to replace my interior light, but have no voltage with or without door switch. Any troubleshooting tips appreciated!

its a switched ground (at the door switches and also the light fixture itself). The hot lead should be back there somewhere.

Thanks, Scott
I've got no voltage at any of the three wires with or without the door switch engaged.

up to 73 power comes from fuse 11 and 74 and up the interlock relay under the seat (this often corrodes) black with red lead.

Thanks, Doc
This is a '74

Did those tips solve your problem?
I have a '74 with a center backpad light that has never worked. I'm going to try the black/red as a power lead. Just connect it as the hot lead?
