1974 Ford Courier lights don't work

Hi everyone. I just bought a 1972 Ford Courier in excellent condition. Paint is original. 1.8 Liter 4 cyl runs great and has been rebuilt withing 5 years. My problem is that the lights don't work. The only one working is the left turn signal on the front but it doesn't work as a park light. I think the right bulb is faulty or it would probably work, I will use a tester on it tomorrow to make sure. The headlights, brake lights, tail lights and rear turn signals do not work at all. I am wondering if the problem could be universal or is there something independent wrong with each of them. I don't have the electrical diagram yet. The parts store didn't have it but will get it Tuesday. I was hoping to get it on the road this weekend. Thanks in advance.

Odd problem, I would start by checking all the bulbs first. Also the connector that goes through the firewall. Maybe it is all corroded. Could be several problem, I would pick one and start to trace it out. It may lead to the whole problem. Since you have 1 directional that works in from, I would probably check the rear on that side first. Wiring in the older cars is usually fairly straight forward.

Don't forget everything needs a ground as well as a hot feed. When troubleshooting it is always a good idea to clip one of your leads right to the negative battery terminal.

I should have mentioned that I checked the fuses. The ones I know about anyway in the fuse box.

Thanks so much. I will start tomorrow tracing wires after checking all the bulbs. It seems unlikely to me that that is the problem because the front turn signals work but it wouldn't make much sense to overlook the easy stuff and then find out I was wrong. I was hoping that it was a fairly common problem with and easy fix.

I would start out by checking the major ground wires.

I don't know much about specific wiring on the Ford, but the typical ground wires are: (1) instrument panel ground (if missing, it will cause many of the problems you are seeing), (2) battery ground to the body (usually a pigtail off the negative battery cable terminal, (3) engine to body ground (usually from a valve cover or engine bolt to the vehicle body, (4) alternator ground (often direct to the negative battery terminal) and (5) rear light wiring harness ground (usually near the taillight assembly).

If all the grounds are good, then start checking the power side, coming through the fuse box.

I am just amazed at this, these things were crap when they were new. Someone must have really taken care of this one. Congratulations on your very unusual good condition old Courier.

Hey, that "ficwriter" handle isn't part of a joke, is it? Naw... it's not April Fools Day.

Seriously, you are lucky to have that truck in good shape.

Sorry it took so long to get back. I had a temporary interruption in internet service. There was a wire missing from the fuse box. I ran a new one and had to replace all the brake and park lights but they are up a running now. This old truck has been well cared for and I intend to continue that care and do a little restoration. It has been running great since I first posted. The manual choke broke but here in the south it starts fine without it so I am not rushing to fix that before I start treating a few rust spots before they really spread. Thanks to everyone for your help.
