Where is the fuse for the dome light? 1986 GMC C3500
I've looked at a bunch of wiring diagrams and don't know what I'm looking at. Fuse location or number would be great but I can't find it on internet searches. No owner's manual.

If the fuse box is the same as mine, 86 Chevy C10, left side 3rd down from the top.

Thanks!
I'm not getting any voltage to the lamp. I'm wondering if it's been disabled by a previous owner since the door basically has to be slammed shut really hard to get it to close all the way. Coming back to a dead battery would drive me to disable the thing somehow if the dome lamp being inadvertently left on was the culprit. The connector in the driver side back pillar is connected. That's the only thing I've checked besides the bulb and voltage at the bulb itself. Now I'll check the fuse. |

Check your door switches, mine were rusted away, and the wiring was no longer attached to the back side. It was just laying loose on the floor..

If you don't have any power on the orange wire at the dome light, make sure the other end is securely plugged in to one of the socket in the BAT bank of the fuse block.
Power to the dome light (and cargo lamp if equipped) is out of fuse labeled HORN/DM, across the shunt - located directly above it - and then to the two columns in the BAT bank: http://s6d8.turboimg.net/t1/24587830_fuse_block.jpg http://s6d8.turboimg.net/t1/24587832_IMAG0081.jpg http://s6d8.turboimg.net/t1/24587831_FuseBlock.jpg http://s6d8.turboimg.net/t1/24587833_IMG_0029.jpg http://s6d8.turboimg.net/t1/24587834_photo.jpg |

While I was gassing up (the truck, not me :D) I looked under the dash at the fuse block. I pulled the 20A fuse that is the HORN/DM and it looks good. There is an orange wire going to a terminal on the BATT bank. I didn't use a voltmeter to verify the batt bank is getting voltage but I will tomorrow when I can see what I'm doing. Too dark right now.

Mine were rusted to the point that the wire was no longer on the door switch. |

Did you get your dome light working?

Re: Where is the fuse for the dome light? 1986 GMC C3500
No I didn't but will look at it tomorrow. I'm getting the truck ready for selling.
It was my Uncle's and I hate to let it go, but need money for other projects. |

Couple of wires were chopped in two under the sill plate on the driver's side. And I need a bulb.

Wires are fixed and I'll get a bulb today.
