my taillights on my85DodgeD150 randomly quit working. the brake lights work but when i turn on my lights for night they dont work at all. oh and when my lights are on my gas gauge doesnt work. ideas?

i would check for wiring issues such as multiple splices and that sort of thing

think you,ve got wires melted together from a bad short did someone by pass a fuze or put to high of an amp one in.you have a short created by athe melted cluster and circuit is not being completed and power is following another path because of it,i have the same truck i drive every day with a short box.had some nightmare wire issues myself with it.

if thats not the problem you have grounding issues,pullall your bulbs make sure there is not a bunch of corrosion under them if thats ok check ground wires for tight and that the steel under them is not pure rust

hey dwayne it was the wiring thanks for the help

My 83 had the same problem. My ground wasn't connected. So just trace the ground (white wire) all the way down. Make sure it makes a complete circuit.

I know this is a 6 year old post. I have a 1986 D150 and having the same problem and was wondering where your problem was in the harness?
