Found the picture below of a 77 fuse panel. I see where the connector is labeled ACCY, which
usually means it's tied directly to the Accessory bus on the back of the panel, which gets power when the ignition switch is in the IGN or ACC position. So this is
probably an un-fused source where you would connect an accessory that is
externally fused, like a radio with an in-line fuse.
It's possible the ACCY connector is being fed by the fuse below which is is only labeled "FUSE", but I'd be surprised. You'd need a voltmeter to find out for sure.
Either way, f the fuse below the ACCY connector is blowing, you have to determine what it's providing power to. Also, since you don't even have to touch the ignition switch to get it to blow, it's either powered by the BAT bus (not the ACCY bus) or you have a short somewhere.
What happens if you don't install the fuse? Does the engine start and run? Do the lights, heater fan, turn signals, horn, etc. work?
