I've replaced all the wiring harnesses with either M&H or Evans harnesses. When I hook up the battery I get the oil and brake light on the dash but no dash lights, no heater fan, no interior lights and no ignition power. I do have headlights and tail lights, emergency flashers, turn signals (fender mounted and tail light), horn, wipers, and light on warning buzzer. Am I missing a ground someplace?

Every problem is a different circuit. Did you check all the fuses with a voltmeter or test light? Don't say they look good test them.

1st what year and car would help. Dash lights could be a bad dimmer switch.Did you check the bulk head plugs,pull apart and put them back together?

69 Coronet. All the switches and gauges were rebuilt/restored, tested. Ammeter was fireproofed.

I haven't tested them yet, I guess never assume new is good...
I have had more that one that fooled me. Plus if there is something wired wrong it might of poked them out. No ignition is odd because that is not on a fuse just a fuse link. With other things working the fuse link is good. Double check the wires on the ignition switch.

I have bought harnesses that had the wires in the wrong spot on the plugs so compare them to your old ones.

Have you checked that your dash frame and chassis is at the same potential? The dash frame needs to have a low resistance to ground if it’s been painted along with the C pillar it could be that the ground connection that is established with the bolts attaching the dash frame to the chassis is not good.

If you don't have power at the ignition switch you will not have a blower motor. Looks like part of the hot side of your fuse box is working but not the Accessory side. All power comes in and goes thru the main spice. Do you have power on the Red wire at the Ignition switch?
