Please accept my appolgy, it was rude of me to yell. (I have removed my rude remarks.)

I do not think that the 80A strip fuse will be a culprit in this case, since you state that the relay sometimes activates, and other times does not. The fuse is a flat strip of metal bridging two phillips screws on top of the relay.



A melted fuse strip does not affect the relay; the coil still energizes and the contacts close, but cannot apply 12V to the GPs since the strip is open.

It may be the ignition switch contact, it may be a connector.

I hope somebody here has a wiring schematic and can help further.

Best Regards,
Jim
