That's not how this works. That's not how this works at all. Think of voltage as a pipe of a certain size, and current as flow within that pipeline. The resistance will increase because the voltage (size of the pipe) will decrease with distance. The current will demand to remain the same as...
I'm not saying that is what happened here, as I have no details but, we tend to add a lot of lights and equipment to our Jeeps and I wonder how many here are aware of the voltage drop and subsequent heat rise associated with the length of the wire run in DC circuits.
My VOSwitches maintain their position as long as the master switch is engaged, whether the engine on or off. I currently have the switch bank operating only when the ignition is on.
Depends on the design. If the rails elevate the cover more than a quarter inch, or if it's ribbed, you would probably be okay.
Interference is ~ 1/4" as measured SWAG. (Scientific Wildass Guess)
Mounted a second hand 50" Rigid 21,384 Lumen Light bar. (17 amp, 243 watt). New, they are about $900. I got it for $200.
A backlit surround for bed lighting and 240 watts for catching Sasquatch.
Mounted with RivNuts because I couldn't get to the underside. I'll get it wired and aimed tomorrow.-
When mine did that, I took it ion to the dealer. Props to Performance of Columbus. Free rental while they had it all day. They have a diagnostic tree to follow and finally found a loose connector. I'm guessing behind the plate in the tailgate?
