so i went to put my camper on the truck and when i plugged it in everything worked fine...
then the next night i had no tail/marker lights on the camper.
the truck lights were still on.
i looked and looked for an aux trailer light fuse and found nothing.
i even pulled all the fuses i thought may have a chance at being the culprit.
finally decided that since the BRAKE lights still worked that i'd just pull the plug and check that.
so i check the voltage with the truck off and i have about 11.5 at the tail light wire on the truck side.
then i take apart the camper side so i can get to the back whilst its plugged in.
i plug it in and i get a big 0 for voltage.
un plug it. 11.5
plug it in 0
so then i test the continuity between both sides of the camper plug, just trying to eliminate all possibilities.
works fine.
its getting late and i'm getting frustrated so i cut the tail light wire on the truck side and on the camper side and used a butt connector.
nothing.
so i drive home with my 4-ways on.
the next morning i'm fiddling around with it and when i test the tail light wire, sometimes i get 4 volts, sometimes 7, sometimes 11. while all the others have 12.5
all of the running lights work on the truck perfectly.
its only for the trailer plug.
to get around it i just ran a new wire to the tail light terminal and up to my switch in the cab i used to use for the LP.
can anyone explain why the truck lights work fine but i have variable LOW voltage for the trailer plug?
