   1991 F-350 
Was messing around in the shop today, thought I would look at the Craftsman battery charger my Son has, that will not work right on his BMW. So I figured I would hook it to the batteries on the 350 and investigate. Turn on the headlights, to give the charger something to do, after maybe 3 or 4 minutes I noticed the clearance lights on the truck went dark. Headlights stayed on. 
Opened the fuse box, fuse In position #4 blown, replaced fuse(15 amp) pulled light switch out, pop goes the fuse. All other lights work, brake, signal, hazard. 
Clearance lights, and dash lights(they are tied together) will blow the fuse. 
Any idea on where to start before prodding around on 30yr old wire harness?

	I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.
