Electrical Problem

[danherrington]

I installed an LED light Bar on my 2008 Ram 1500; all works perfectly. Next morning I drove 45 miles to a friend's, left the truck overnight and returned next afternoon. I have no electricity to anything; dome light, headlights, light bar, dashboard, starter - nothing. Battery is reading 12.9 volts. I knocked some dust out of plugs on back side of fuse box and still nothing. What should I try next.

You must have a parasitic drain from the install possible. Did you wire directly to battery? Did you test battery? I wired my Ditch lights directly to battery. Never had an issue. Maybe you inadvertently disturbed something? Catch a wire? Check your grounds? Just suggestions.

Is that 12.9 volts sitting I assume? Seems to be in the normal range.

Definitely should be over 13 if running.
