Well, I spent 45 mins trying to articulate this problem and lost it all when I tried to Review the post so I'm going to cut to the chase. I have a pretty good technical background but... this is an RV...
Awning and door steps LED strips stopped lighting after 2 years.
No fuses blown... originally. (more on this later)
Switch is proven to be good. Same switch operates both sets and only those two sets of LEDs.
12vdc potential across terminals of switch in OFF position, goes to 0 when turned on... seeming like the circuit is being made... right? But no lights.
The measurement at the connection in the awning brace for the awning LEDs is Ov when turned on or off. I haven't tried to measure at the LEDs under the steps.
I've taken some other measurements which is too much to try to articulate here, but have only succeeded in confusing myself (LOL), which may in part be because the switch feeds both sets of LEDs or because I don't know enough about how RVs are wired.
I tried running a wire externally from the switch to the awning LED strip, bypassing what I thought was maybe a bad wire, but it didn't help. Only then did I discover/realize that the wire I removed and bypassed is the one with 12v on it!
Although, it's the same ORG/WHT
looking wire that is at the awning brace connection. I'll stop there.
Now, after all the troubleshooting and putting the wires back in original configuration (I promise), when the switch is turned on, the inverter kicks on and it blows the fuse for that circuit! As if there is a short somewhere... I'm not sure what I could have done and see no visible damage
Anyway... maybe is someone has seen this same type of issue on their rig and can offer some insight.
Can I just connect the awning LED strip directly to the battery to try to eliminate it as an issue? It appears to have voltage regulation built in.
Thanks in advance!
