Tailight Wiring '62 Overlander

[Deppdog]

I have a 1962 Overlander which I picked up a month or so ago. Upon inspection of the exterior lights - brake, turn, running etc. I have found a problem I can't solve. All of the exterior lighting works perfectly, except for when I turn on the right turn signal. When the right signal is activated, the left signal blinks as well - like hazard lights are on. No other lights are affected by this or any other variable of light operation. I have checked the truck plug end and it is OK. I have checked the plug end on the trailer and all is wired correctly with the truck end. I have checked the wiring at the access panel in front and it checks out OK - that's as far as I could get without tearing into panels. Any ideas? Anyone know where the wiring runs from the access panel?

Thanks in advance!

is that you probably have a short in the right taillight between the right turn signal wire and the brake light wire. Could be corrosion in the lamp holders.

If the short isn't in the taillight itself, it must be in the wiring from the umbilical to the tail light. The plug is a good suspect since it takes only one stray strand inside to short two circuits together.

Sounds like a bad ground somewhere which is causing the right lamp to seek a ground wherever it can, in this case it is finding it thru the left signal lamp, giving it a ghostly flicker, yes? Don't ask me exactly how it does it but it does happen, I have seen it many times before. Pull the taillamp bulbs and check the sockets, they are probably loose or corroded, may be time for new lamp assemblies.
