Clearance Lights Trouble--Fixed :)
Have one string of three back clearance lights that won't light now. Two did and an end one didn't before I tried to fix that one.
Each fixture has one lamp terminal to a screw hole so it grounds on the skin of the camper (it seems) and the other lamp terminal has a yellow wire to it.
The yellow wire on the end one that wasn't working is single to the fixture but (I assume it's the same wire) goes in and out of the other two fixtures so it looks like two yellow wires on the back of each of them, but I think it is all one wire for the three lamps. ???
Down at the 7-pin where the #3 green comes into the camper it splits into three green wires and they go up inside somewhere. Each of the three greens has 12v.
At each of the three lamps that are not on, I am getting just a tiny voltage like 0.03 instead of 12v
I don't know where the green changes to yellow. My next move is to take out the tail light fixture (which works) and see if the yellow goes up from there to those three clearance lights on that side of the camper, but first --
Anybody familiar with this situation? Getting frustrating.
Do the three bulbs have to be in so it all works? I took out a bulb over on the left side string and the other lamps stayed on, so I suspect that isn't it.
Of course I managed to short out the whole circuit back to the 7-pin a couple times, so now I know where the 15a fuse is for that in my truck :( Anyway, truck fuse ok, pin #3 ok, front yellow lights on, left side back upper red lights on, left and right tail lights on, right side upper red lights (two on back, one around on the side at back) not on. The middle upper red light at the back is on.
So I am off to an auto store for some more 15a fuses and clearance lamp bulbs, and am hoping to find out what to do right here when I get back :) Thanks!
