Back from a recent trip, I noticed a brown mark on the front of my 2013 Hawk. Thinking it was dirt, I discovered that in fact it was the vinyl discolored due to the solar butt connector at the front heating up. I've had the same solar panels up for the last two years (3x120w) and didn't notice any issues until now. I'm guessing, the connection has gone bad and resulted in a poor connection, thus causing the heat. I cut them out and rewired the connection, this time soldering with heat shrink wrap. It was tough working behind the collapsable panels to gain access to the wires.
I'm surprised with couple issues.
1. I did not measure any high resistance from the clipped out butt connections.
2. There were 3 wires coming from the roof. Yellow for fan and lights. Red/Black (hot/ground) from solar panels. The yellow did not have a splice. Why did FWC not have a continuous run instead of making butt connection at the front collapsable panels?
At this point, I'm guessing the bad connection was intermittent. Any feedback would be appreciated.
