67 Electrical help requested
My 67 recently lost temp gauge, fuel gauge, back up lights and in dash parking brake light operations. I've checked and found no power at back up light connection on firewall down to switch. It appears temp sender resistance is good. No movement on temp gauge when grounding out sender wire. I have replaced 10 A fuse on top position of fuse block twice. Is there another connector or is this a wiring issue from the fuse block or something else? Any help or thoughts would be appreciated.

I don't know those specifics, but multiple issues makes me think firewall connector, or ground to panel. Easy to run a second ground to neg terminal of battery. Firewall connector, disconnect battery, remove connector and brush with brass wire brush. Good luck!

Use a voltmeter, if you have 12v on both sides of the fuse, the problem is in the pink wire going to those things that aren't working. If you have 12volts on neither side of the fuse the problem is on the pink wire coming from the ignition switch to the back of the fuse box. If you have 12v on the left side of the fuse and nothing on the right side, the fuse is no good.
You can connect a jumper from a 12v connection the the left side of the fuse and it those things work, it also tells you that you have no 12v leaving the ign switch or getting to the fuse box.
