How 12v lights work?

Water in the awning lights is real possibility. So is a short in the LED strip itself.

If the LED strip has a plug on the end it would be a convenient place to test. If its soldered on then thing are harder. How are your electronics skills?

No, it goes through the wall and connects to the panel.

Part of my test kit is a 2-prong turn-signal flasher with jumper wires attached. Hook it in place of fuse, will work as auto reset circuit breaker. Then you can follow the wires with non-contact amp meter. When you pass the short the needle will stop jumping.

If the fuse opens when you turn on the switch.... the trouble is after the switch. Probably a bare, cut or frayed wire is shorting to ground between the switch and the lamps.

Did this ever work? Or is this part of a new installation?

Sounds like you have a short in the awning wiring? I assume it does this whether you are on just battery or 120v?

And it's just the awning light that blows the fuse either way?

Turn on your inside lights on and no problem?

Turn on your awning light and it blows the fuse?

Or a combo of both?

Not sure how you test that, but you gotta somehow take the internal wiring out of the equation with some test wires to see if it's the fixture or the wiring?

Good luck! Mitch

From the awning into the wall.

Yes, these are LEDs

checked the cable that goes inside

Goes inside to where?

Are these LEDs or not?

I have the main internal lights and awning led on the same 15amp fuse.
I inspected and disconnected the awning lights, checked the cable that goes inside, checked the switch, all good, but still it blows the fuse.
The panel looks good (not sure what to check).
The only thing that I cannot inspect, is the cable that goes from the panel to the switch, inside the wall.

Any idea what can be wrong and how to troubleshoot it?

Exactly.^^^^

Unless you have added a 12VDC Circuit to exterior typically awning lights are AC

Which 'fuse' is blowing?


On SHore Power........AC goes to Converter
Converter supplies the DC to the FUSED circuits AND maintain battery

W/O shore power Battery then supplies the DC Fused circuits
