Awning light only getting 8.5v
My LED awning lights quit working, and troubleshooting the. They are only getting 8.5v. I checked at the switch, and I've got 12v coming out of the switch. I connected the directly to the battery wit...

An excellent way to check your lights is to take a wire from the battery negative, and connect to the LED lights negative. If that makes things bright, then you are looking at the negative return from the lights.
If that does not, take the same wire from the battery positive to the lights positive. If that makes them bright, then you are looking at a problem in the positive feed, and likely voltage sharing with another load that would be taking the other 3.5 volts.
Is there another light, perhaps one that is usually bright when the LED lights are on, but now is off, or just barely dim?
It's an odd thing with two devices that normally run from +12 to ground, but the ground is not there so they run in a series circuit. The brighter the filament normally, the dimmer it is in a series circuit with a normally dimmer filament when sharing the available voltage.
