Okay kids, I am stumped on this one. I just rewired my TTT (aka my 1965 Shasta Compact, "Sparky the Wonder Trailer.") My wiring harness on my tow vehicle isn't working right now and I am trying to test the trailer lights by using a lawnmower battery. I will get the tow vehicle fixed next week.
So I hook up my trusty lawnmower battery and everything works. There are only right turn, left turn, brake lights, a license plate light, and two side running lights per side -- an amber and a red per side. Only outside lights -- no 12-volt inside lights at all.
Everything works I say -- except the amber and red side running lights. Wierd. The bulbs are new -- in fact I replaced the old running lights with brand new ones. The license plate light runs off the running light circuit (brown wire) on the door side and my 12-volt tester shows the wires are hot, the light sockets are hot -- but somehow the side lights don't light up. The back running lights, however, work like a champ and just like the license plate light, these lights run from the same circuit.
Doh! I can't figure out how the side lights can't work when other lights that run from them work okay.
Any ideas out there? I think I might possibly be losing my mind. But that's okay, I can probably pick up another one at HD.
