Turn signals blowing fuse #4 - ERA 782

I think first I'm going to disconnect the wire from the dimmer relay and run the turn signals in both directions and see if I pick up some voltage on it when I turn the left signal on. I'll also check if the other side feeds power through the relay to the switch even when the HLs are off. At leas then I will pretty much understand how everything works.

Probably at that point I'm going to pull the wheel and the switch out to test.

Stay tuned.

Surprisingly with the tan wire from the dimmer relay disconnected - I don't pick up any significant voltage from the switch side when running the left turn signal. I thought sure I would pick up shorted voltage through it. Nothing on the relay side either.

And it is 0-volts when HLs are off.

Crap - it fixed itself (temporarily). Turn signals don't blow the fuse now. Nothing like an intermittent fault to worry about.

That's actually good. You jiggled a wire, or jiggled something, that cleared the fault -- you can jiggle it back. Put a 12v trouble light on the fused side of #4, so that it's lit when the fuse is good, and so that you can see it easily. Then turn your signal lights on and start wiggling stuff until you see your trouble light go out.

No luck - I messed around with it some more - even pulled the steering wheel hub and loosened the switch to move it around. The switch appears to be a sealed unit so I don't think there is much I can do there. I made up a baggie of spare fuses to keep in my glove box and I think that is all I can do for now. Not completely satisfying.
