The Stovebolt Site Forums The Shop Area The Electrical Bay 6 volt turn indicators ... quite a dilemma

******************************* I was working on all of this and did not see what you had posted *************************** I do not want to delete this just yet, but I can not go back and review this evening ... I'm done. Long day in the truck and I'm fried. Talk more tomorrow.

Diodes??

Well, for one, I'm not that concerned about the pilot lights. I think the 700 flashes them anyway. Two, I thought you all jumped my (bad word omitted) for originally wanting to go with diodes ... ok...

Anyway, based on all the great input, here is my diagram of what I intended as my initial bench test. Remembering:

1. The signal stat 700 has 5 wires: power input; left front; left rear; right front; and right rear.
2. My front parking lights have been modified to a 2 filament socket (marker light and bright/turn sig). The bright side ONLY functions as a turn signal. It does not need to share the circuit with any other signal (like a brake ...).
3. In an initial bench test, the 700 powered 2 (at a time) turn signals with one flasher just fine. I do not have enough functional turn signals (offboard of the truck) to do an all up test. I was thinking an all up round test was not required, due to the turn signals only needing two at a time anyway, but am rethinking that because of the need to include brake lights in the test. So I may have to get two more turn signals functioning.
4. Only the two rear lights need a dual function bright side.

Do relays not prevent backfeeding? I can see where that could be an issue.

At anyrate, given all the above, here's my back of the envelope stab at a wire diagram for my bench test. I do not depict the marker light circuit as it is irrelevant to this system.

Thanks,
John
