Dim 12v light???

[Mudcat21]

Built a new shack and went to check the 12v hookup (hooked it to a running truck) to the light bulb and it gives off barely any light. It was late last night when I got done and didn't have a chance for any trouble shooting. But my guess is that a connection is bad somewhere. Any other guesses? Thanks for the help

First thing I'd look into is the ground wire to the truck.

I guess if you hooked the shacks lighting to a battery you'd find out fast if the problem is on the trucks end o the shacks.

Dim bulbs are typically associated with bad grounds.
