That is a dual fuse, 40 amp on 1 side and 120 amp on the other, the terminals on each side should have continuity to the center blade. I'm curious as to what blew the fuse and which side.
To answer.....The 40 AMP side is still intact but the 120 side is not. (VIA multimeter test) Also the engine turns over but won't start and nothing
else works. Simply no power to the fuse panel.
As to your question Dave to "What Happened"?.....In a hurry to ride
I was charging my GL1800 battery (still installed on the bike) and tried to start the bike while still connected to the charger. (I know..."DUMB" Got it) It only "starter chattered" because the battery was still weak and then I smelled the burn. So straight to the fuse box and after checking "ALL" fuses, found #4 Main fuse burnt. After waiting for the charge to finish, replacing the fuse AND disconnecting the charger I attempted another start. Engine turned over like a champ but no start. I didn't want to damage my starter so without the smell of burnt fuel or dash lights etc, I stopped and continued trouble shooting and found the 120/40 fuse was opened on the 120 side.
So learning the fuse is double sided with the 40 AMP side still intact (allowing the starter to turn) and the 120 side open (stopping power to the fuse panel and all of the accessories) it was time for a new fuse.
The fuse is ordered and should be here early this week. Thanks for everyone's input. I will post the result of the new fuse install here.
I believe ignorance is not stupidity, not learning from the lesson is stupid. And sharing an experience may benefit someone else.
