Found my dads original 1971 duster!

Hey guys. Also if anyone has any pics of installing the rear hardboard panel and the back vinyl door panels that would be awesome. I’m not sure what order they would be done in and also if I might be missing some hardware, trims etc. I got things back in shambles. I’m going to try to tackle those things tomorrow. Thanks!

Oh boy!

The later panels like yours may have more grounds than my 67 but the three I mentioned are the ones I know for the interior.
In theory the instrument board will be grounded simply by mounting it, but at least on mine I found the factory had ground wire from the capacitor mounting screw to the radio support strut. I didn't see cap on your dash. I *think* it may not be needed if an electronic IVR is installed.

Loose wires - broken connectors. Any of them could have been a short, or a short waiting to happen.

Hey, Mattax. So quick question. I cant find any loose wires, bad connections etc. If I have the dash out, those 2 wires (red and black bolted together) it obviously now lets the car start….but should I also have power to the headlights, interior lights, signals etc (everything that doesn’t need the IVR conversion to 6 volts)?
I’ve never been able to get power to any of these yet. Or does the dash need to be installed back into the car to power this stuff up?
Sorry for the probably obvious question, the wiring end of things is just very confusing for me. Thanks
 
@Capt46.. that picture you posted for the rear defrost, whats the sheetmetal bracket for? whats it bolt to?... thanks

I was going to suggest trying to trace things on a wiring diagram, but the diagram I have of a '71 sucks. But then I went to my '74 diagram and struggled with that one too, so must just be too early.

Have you checked for missing/bad fuses?

Headlights won't work without the dimmer switch on the floor. Is that plugged in?

Best I can tell, looks like the turn signal switch is pretty important in the function of the lights, is that still plugged in?

Best I got. Maybe Mattax has better/more ideas.

Thanks! I’ll check those. I agree!! I can’t make heads or tails from the wiring diagrams I’ve found or been show. But again, without a base knowledge it’s very hard for me to understand what I’m looking at anyway

Sorry. Yes, I’ve checked all fuses

Best suggestion I have, is if you can make paper copies take one and trace the wires with a highlighter or something. Find a component you think should work and trace whatever wires are connected to it back to their source. Use different colors for each wire. One of them should go back to power, either through a switch or fuse.

Did you check both sides of the fuse for power? There should be 2 that are hot at all times, 3 more that are hot with the ignition on and the last one hot when the headlights are on. At least as best I can tell from the wiring diagram I have.

Thanks! I’ll try to see. So eliminating the dash and IVR won’t have anything to do with that? Lights etc should still work? The rallye dash with all the gauges is out of the car. I take it in on wed to have it repaired and solid state system put in it

As long as the 2 amp gauge wires are connected, having the dash out shouldn't matter. Per what I can tell from the wiring diagram I have. But if the turn signal switch is out, the tail lights and such might not work. Interior lights should though.

My bet is the fuse box is bad and you don't have power on the fuse for the lights. But just a guess, you need to check it.

While they have it, ask them about converting the Ammeter to a Voltmeter and make your decision based on what you hear.
 
Hey guys. So Mr. Heater Box replaced my oil pressure gauge (it was fried), replaced my IVR to solid state, added LED lights and calibrated everything today. The said that my ignition might not have worked when the wires were hooked to the ammeter because the builder used a speed nut on one of them. So I am hopeful. That still doesn’t explain no lights etc, but maybe that’s a different issue. I have some wiring questions before I try it again though. There are several wires that I don’t know where they go. I can’t find anywhere to to connect them to. See attached pics. Any help would be greatly appreciated. Again, I’m sorry for my inability to grasp this stuff. Thanks
**also the last pic shows the sheet that they gave me today. I can’t find any of the 3 wires that are supposed to go to the back of the printed circuit. 2 of the ones I sent pictures of and circled are the right colour, but their connectors are way to big to push onto the 3 posts. Also, I don’t think they were hooked up when I picked up the car

Also in these pics it shows the ground that comes off the light harness at front of car and the engine ground. I’m told that these are both terrible grounds. Could this have anything to do with my issues? I have someone getting me proper engine ground cable tomorrow. The front light harness ground is completely loose and doesn’t even look like he scraped paint off to make contact. The engine one is grounded to something that appears to have a gasket between it and the firewall, so I’m not sure how that could ground at all
Obviously I’m going to fix both of them, just wondering if these could be the cause of no lights etc

This is the headlight switch harness. The black wire was hanging beside it. Im not sure if the wires are all in the right place in the harness or if the black one should actually be pushed into one of the slots or maybe onto the extra post coming off the switch….or if it has anything to do with the switch at all

Top pic......Big one (should be 2 pieces) wiper switch

......The other 2....Check fan switch, heater box and radio (In my pic, 4 & 5 are fan switch and heater box. My car is non radio so that plug is wrapped up in the harness and not used but I believe it is similar)

2nd pic......Cig lighter. See pic. and compare wires and plugs


3rd pic.......Small printed circuit board.

Not sure about the orange......That colour is usually associated with a dimable light circuit.....Long wire, maybe console light?

Let me know if you need a pic or 2 of my light switch harness. Mine is a '71 also.

Thank you so much!! That helps tremendously! I think you pretty much answered all of them for me. I should have known the one for the 3 on back of circuit board. I forgot about that one. I was confused on wiper plug, but after looking closer after your response, I saw that it has one empty slot and fits!

The only thing I’m worried about with my light switch is if the builder put the wires into the body of the harness in the wrong orientation

I pick up a reproduction radio tomorrow. I got a speaker the other day. I’m assuming that 2 of the wires might be for it

Again, thanks a million

Where is that orange one going on yours? Through the hole next to cigarette lighter?

Let me know if you want a pic of the light switch plug. I can get it for you tomorrow if you want.
