Master (dogbone) 30 amp fuse is the first place I'd look.

Just a heads up. The dogbone can look good but have almost microscopic cracks that cause intermittent loss of power when hot. When it cools it reconnects.

dogbone is solid.other possibilities besides ignition switch ?

Does everything go dark, or just the ignition? What do you do to get it going again?

I once had one that occured a couple of times when I turned the handlebars all the way over, I think to the left. It happened once in a parking lot when I parked and locked it. It blew the fuse. I figured it was a weak fuse and forgot about it. A couple of months later the lights flickered once when moving it inside the garage, again, moving the handlebars hard over. Did NOT hurt the fuse that time. It was a 1984 Interstate, 44k on it. I suspected the wiring harness by the forks, but I never took the fairing off to investigate it any further.



I have a 1981 Silverwing that had the fairing removed by the PO. The big ol' harness lays there by the triple clamp and you can see it bending back and forth when you move the bars around. So far, I have not had a problem. I guess the wires are there and have to flex somewhat on every bike.

OK, on my 84, I am thinking it flickered, and went dead in a bank parking lot, when I turned in to park. I jiggled it when I went to get on, and no joy. I think I blew the fuse when I removed the cover and checked the battery connection (+) withmy really cool Swis Army Knifescrewdriver. I remember having an impression of the screwdriver burned into my finger for a couple of days.



Anywho, when I replaced the fuse it was ok, and she had power.

Above the solenoid is a big plug.It canget hot and burn up like the stator plug. Symptoms sound right for that happening to your bike. It's actually fairly common.

BTW, welcome to the forum.

Might also check the main ground cable where it connects to the engine and frame for corrision. Common problem with all old wings.

Like dingdong said check for loose grounds and connectors and dog bone.
