Hi guys, I am building myself a small trailer and I was wondering if any of you out there are good with trailers my question is this :
I'm using a 4 way connection plug and I've now wire the whole trailer but before I hook up the 4 way harness to my wires I wanted to test them with a battery pack so what I did is ground my battery pack to the trailer and I than proceed to test each wires.
I touch the yellow one and the left light came on, which should be ok, than I touch the green wire and the right light came on which is ok too, but when I touch the brown wire all the lights came on (side markers too) but for some reason the left one didn't ??
so I guess what I'm asking, is this OK still I know once the 4 way plug is hook up to a car or truck that power might go to more than one wire at the time but for testing purpose only if I want to test the trailer by testing one wire at the time are my result OK ? I'm wiring this trailer for a friend so I don't have a car to test it right now.
