Question type: Maintenance & Repair

I have a 1980 Grand Prix 3.8L on the wiring
diagram is says there is a fusible link but I don’t
know what end it is can someone help?

Follow the positive lead wire either to or from whatever system or device it is operating. It looks like an inline fuse and can be checked by measuring either the resistance across it or the voltage on either side of it. Resistance will be zero and voltage will probably 12-14 V to ground if good.

Thanks found the problem, had corrosion on the positive battery terminal
