Yep did that thanks thoughAccidentally reverse the solar panel connectors? Use your meter to confirm polarity.

Just added two pics of what I have gotIf your multimeter can measure the short circuit amps, you can do that in the trailer. My multimeter can measure 10 amps. When the panels are in the sun and the leads are not connected to anything, you can measure amps across the leads. Just be sure not to exceed the amps of the multimeter, or the DMM fuse will blow.
Also, depending on planes voltage, you can have an arc. My panels at 52 volts and three amps arced about a 1/4 of an inch when I tried the amp test.
You can do this amp test by disconnecting the wires of the SCC. Just get the wires a bit away from the SCC and don’t short the wires together during the process. I shut my circuit breaker off for the panels when I move the wire.
The amp test is fairly quick.
This is with panel completely in the sun with no shading?Got voltage but no amps at all
Shown in pics
Yes but i have some that look a little like that too but no problems (yet?). You're getting decent voltage but not familiar with troubleshooting them for no amps. I've never had a panel fail so lacking in that area.Dies it look like water has got in?
How do I put meter across that to check pleaseIf you can open that compartment on the back of the panel then you can check the resistance from each end of the cable and the terminal inside of the compartment to see if either one of the cable shows high resistance or not.
