Re: tail lights stop working after starting up the truck

I suspect it’s a ground because I’m getting 14v with the truck running at the bulb. It seams to take a bit and it seams to be when the alternator is marking voltage so that also makes me wonder if the ground can’t handle the higher voltage but when it’s 11.5 to 12.5 volts the ground is handling it. I just need some time to go though all the grounds and wiring.
