Greetings,
1976 F100, 300ci 6 cylinder, 3 speed - column.
I'm trying to identify a fuse that is not listed in my Chilton Manual. It is a half-size, 15 amp fuse marked (I think) Court (or Cont). It's located upper-left on the fuse box under the dash, drivers side. I was tracing a short from the starter solinoid and found this fuse shorted to ground. I removed the fuse, the short went away and all appears well. The lights, signals, fan, etc... all still operate. The truck has no AC (it does have the pully for an AC belt). No power steering, brakes, etc... There is one green and one green/yellow wire attached to the back of the fuse box for this fuse. Any ideas are greatly appreciated.

courtesy lights??

Aha! That's probably it. The dome light has been missing the bulb for about 20 years so I didn't notice it when I was testing everything else. At least now I have a place to begin looking for the short... Or I can just leave the fuse out.
Thanks!

Hi prbearden. Thought you would find this interesting. Note circuit #53 & 54

Thanks Fordification for the chart. More info here http://fordification.net/tech/wiring.htm

Thanks! I guess the switch doesn't believe the doors are closed. Maybe now, after 20 years without a dome light, I'll check the switches and buy a bulb. It's ironic that the one fuse that gave me all the trouble is not on the wiring diagram (at leaset I couldn't find it) in my manual.
