    I have an 83 Chevy K10. I was driving a couple days ago and lost my dash lights, marker lights and tail lights. when you pull the knob for the lights the dome light and a light under the dash come on. We tested the headlight switch and it was bad. I replaced it today and nothing changed. I checked the fuse panel and I'm not getting any power to that fuse. Someone also took out the 5amp fuse and replaced it with a 25amp. It must have been like this for years because I never had to replace it.

    I looked on autozone for the wiring diagram and it kinda sucks. I was wondering if someone had a website to get a good diagram from. I think I'm going to have to do a lot of troubleshooting before the next storm.

    tail / dash light issues

    hi,tail lighs and dash lights are the same fuse..checkthe black ground wire at rear tail lights.(behind and below tail lights.)prone to breaking off the black ground wire,also check the the ground wire from bed to frame.and groundwire fro cab to frame.or may have burned-melted tail light harness wires on passenger side frame rail..caused by hot exhaust pipe.= dead short.ok..

    the wiring runs down the left frame rail not the right. and is tucked up in the box cross bar for the left to right lights.

    and yep the tab were the ground bolts to the box behind the left tail light housing rots off.

    I'm going to pull it into the shop tonight and trace down all the wires. I have checked all the wires under the dash. Hopefully it is just a broken ground. Thanks for all the help!!!!!!!!
