I've had some issues with the tail lights and running lights working intermittently and have been thinking that I want to rework all of the plastic housed crimped connections to soldered connections. What's been happening is that some of individual taillight LED's work some of the time and sometimes it clears up and they all work. I've had similar issues with the side running lights. I've cleaned the tv to trailer 7-pin connections a number of times with mixed results, sometimes that helps, but the problem returns. The fact that occasionally all of the individual LED's in the taillights do operate has me suspecting that I may have some faulty connections.
My question is can I run the 120V system in the trailer while I'm working on the 12V wiring to the running lights? I keep the trailer plugged into 120V while it's parked next to the house and, this being summer and all, it'd be a little more comfortable if I could operate the AC while I'm crawling over the benches to get to the wiring.
Thanks in advance for any help or insight you can offer.
