Hmm, I tested the output connections on my f150. But, the trailer lights not working. It's 6 months old, a Camping World purchase. I tried to trace the wires for obvious issues but they tuck into the frame..
Most of the time, it is a ground issue.
I agree that most of the time its a loose wire/ground issue. If the unit is only 6 months old I think I'd just bring it in for warranty work if the dealer isn't too far. It becomes a point of principle for me at that point...even if you can trace the electrical you shouldnt have to on a unit thats less than a year old.
Thanks.
it is a 3 hour drive to Camping world where we bought it...which wastes a day I suppose. I will check ground.
Did you clean the connectors on the plug? A Q-tip with alcohol, followed with a light coating of silicone grease may fix it?
I had a small soft wire brush and cleaned the contacts. sprayed them with WD40 then wiped them off. I'm due to spend an afternoon on a more deliberate attempt however
update on my wiring issue. All the running lights didn't work, the passenger side turn and brake lights also not working. Even though I am under warranty, I decided to bring the QS 10 to a local respected RV repair shop. I have a trip coming Saturday. Also, my dealer is 3 hours away and I'd have to leave it. ...that means two round trips. $80 in gas at least.
So, the local RV repair found the issue. I picked it up this morning. Quote from the repair/wiring guy was that the "wiring looked like it was done by a jr high kid"
Oh well, cost me a fair amount to have it rushed. That's on me. But, i'm back in business, safe anyhow.
Thew shop suggested I try to recoup my expense somehow. Not sure if that would work.
Its worth a call to LL to see if they will work with you.
