    I'm trying to figure out what went wrong here... I put 2 LED work lights wired to the load light switch (turns on the light on the back of the cab) and they were working fine, I then move the location of the lights a few inches and hooked up everything the same, power to power and new ground at new mount locations. NOW I flip the switch and they don't turn on. YES I CHECKED THE FUSE AND RELAY lol.. I checked all fuses and they're all good, checked the relay and it clicks. I don't have power at the dash switch and the little green oval that turns on when the switch it's "on" doesn't come up. I know I need power to the switch but where did the power go if it was working just fine before!?? I'm breaking my head per this, please help, what am I missing.

    2010 Peterbilt 384, 48" sleeper.
    The Load light fuse and relay were found under the sleeper bed, I didn't find anything on the fuse box next to the clutch, or the one behind the dash. Please help! I know I'm missing something

    The led lights can only be plugged in one way. Try reversing pos and neg connections.

    Have you checked to see if you power to the switch?

    They are plugged in the right way, they were working just fine before I move them, connected them the same exact way

    Yup and I have to no power to the switch. That's why I thought it was a fuse, but fuses are good

    Well take your pick,start at fuse or switch and trace the wire,or bypass and run new wire.

    That's what I think I'll do. Could there me something else beside the fuse I looked at? Maybe another fuse somewhere or something that needs to be reset? I found it weird how I only saw a "Load light" fuse under the sleeper and not on the main fuse panel. What do you think?

    It's gotta be something simple and easy I'm probably not seeing, it was working just fine and then it went black.. A real headache here.. Anyone else with input?

    It's a ground issue. You left everything the same minus the ground was moved..... So where does the ground you're bolted to really ground of to?

    Don't know,if you have a multi-meter check for continuity between fuse and switch.
