Initially the right hand turn lights on our 1974 Trade Wind Landyacht weren't functioning and then the entire right side of the trailer's lights stopped working.
We discovered that there were two wires that were not connected on the truck end of our Pollack receiver where it plugs into the much longer portion of the umbilical. We cleaned all of the connectors with sand paper and the small wire burr/brush on a dremel and attached the two loose wires to where we thought they were supposed to be connected.
We found a electrical receiver diagram/schmatic online at:
TRAILER LIGHT WIRING - TYPICAL TRAILER LIGHT WIRING DIAGRAM / SCHEMATIC - Trailer Parts & Accessories - Chuck's Chevy Truck Pages.com
It's states it for Chevy trucks, we have a 1996 Dodge Ram 2500 TV. Does that matter? We couldn't find anything about what color wire goes where and are now thoroughly confused because the wires attach to the back of the thingy that looks like a flower made of prongs. (It's Gemma typing-Murray just got frustrated and went to bed). Does it matter what wire goes where? It's got to! But based on the diagram, it seems that the wires don't correspond with the diagram.
We tried the umbilical at 12:30am and now the none of the trailer's lights are working and neither are the right and left turn signals on our TV! Did we short the TV? The trailer? Did we blow a fuse on the TV? Trailer?
So . . . for those of you that may be up at this time . . .
Can we fix this quickly and/or easily? We're supposed to going to Yosemite later today!
Should we just go buy the short wire doohickey? Where can we buy one in San Francisco. We're not very close to Camping World. Walmart? Auto Zone? Around how much will it cost?
Any insight or information would be appreciated,
