Okay, before anyone else says it, yes, I'm an idiot. Now we have that out the way...
I've been trying to troubleshoot to figure out why my horn isn't working. Last night I thought I'd narrowed it down to the switch and then as I was looking at the wiring diagram my brain had a bright idea. I figured if I jumped a wire from 30 to 87 on the horn relay base it would bypass the need for the solenoid to be triggered thus bypassing the need for the switch, and if everything else in the circuit was working the horns should sound. So I just tried it and they didn't. (Was I wrong?) Then, and now I've stopped to think about it I have no idea why, I decided to take that wire out and instead jump it from 85 to 86 and... puff... a cloud of smoke wafts from under my dash and I quickly turn off the ignition. On closer inspection I've melted the brown wire (that haynes says should be brown/white) and the red/white wire that both go into the relay base. And I also noticed a brown wire attached to the ground by the fuse box has a blister in it too, although I'm not sure how those two things are connected? So, what did I do and what do I need to do next? And why didn't fuse 8 pop and save me from myself? Any advice much appreciated. Thanks John |

When you jumped 85 to 86 you shorted out the coil of the horn relay. Same as shorting battery + to ground! With expected results, max amps and burned wires. There is another problem in your horn circuit that you need to find.
Fuse #8 didn't pop because the power to the horn relay #86 comes from the "hot" side of fuse #8, not the fused side. When you jumped 30 to 87 on the horn relay, the horn should have sounded. If not, there is a problem with the wiring to the horn or the horn itself. It may be an open or a bad horn. Tom |
