Posted: Wed Jun 20, 2012 6:42 pm Post subject: Strange light problem
I installed the old, relay style turn signal upgrade. All my lights work, except the rear passenger side turn signal. I checked the wire going from the relay box to the light, it was fine. I checked the post on the relay box. The incoming wire from the directionals flashed, the post for the outgoing wire to the front turn signal flashed. The post for the rear turn signal had no current going to it. So, the bad connection is in the box. does anyone know if there is a fuse in the box, before I take it apart? Right now, I have a single cross wire going over from the working front light to the post for the tail light. It provides it with a flashing charge, and the rear turn signal now lights. This is kind of a ghetto rigged contraption though, and I wonder both if it is stable, and if I can fix the problem without having to try and find another box.
The other thing I noticed, is that the directionals work in "stop light mode". They don't work in full drive lights, unless I flick over to stop light, then back to drive lights. Then they work fine, as many times as I use them.

but I would love to get some advice from someone who knows far more than me!
I installed the old, relay style turn signal upgrade. All the lights were working. Then, suddenly, the turn signals, and the rear taillights, stopped working. I cleaned all the connectors, loosened, checked the pins, and then tightened, the 3 lever light switch. Took the lens covers off the affected lights, checked the bulbs and wiring, and fixed them back in place. Now, all my lights worked, except the rear passenger side turn signal. I checked the wire going from the relay box to the light, it was fine. I checked the post on the relay box. The incoming posted flashed, the post for the outgoing wire to the front turn signal flashed. The post for the rear turn signal had no current going to it. So, the bad connection is in the box. does anyone know if there is a fuse in the box, before I take it apart? Right now, I have a single cross wire going over from the working front light to the post for the tail light. It provides it with a flashing charge, and the rear turn signal now lights. This is kind of a ghetto rigged contraption though, and I wonder both if it is stable, and if I can fix the problem without having to try and find another box.

I don't know why my earlier post was put up on the page, but I'm just trying to get someone who knows anything about this to help me out. I figured if I retitled the thread it might grab the relevant person's attention _________________ 1952 M38A1

I dropped it. Multiple repeats of a post take up unnecessary band width. If you want to draw attention to a post you're not getting any response on just bump it back to the top of the page and/or edit your post title. The post only needs to be written and posted once. From then on edit it or bump it.
The most likely reason for the lack of response is the lack of folks actually using and familiar with the early flasher box. When you open the box you will find three relays, a resistor and a flasher. No fuses. There aren't any known supply of parts for that unit so if you can't make her work by standard troubleshooting procedures and cleaning and adjusting relay contacts you will have to buy another box. This is why I suggested you just go with a standard civvy 900 series turn signal set-up when you first asked about the old flasher box set up.
I had some internal wiring diagrams and a circuit analysis that Tom Mackie put together a couple of years ago but I can't seem to locate them.
