Blown fuses or relays?

I would start by checking all the fuses.Especially the large fuses in the under-hood fuse box.

That circuit is fused, most likely with a large fuse bolted in the under-hood fuse box. Typically it will be a 100 to 150 amp fuse. On older cars a fuse link wire was used. Those are simply a short section of smaller gauge wire but the insulation is special. It will not melt or burn. You test a fuse link wire by tugging on it. If it is still good, it will act like a piece of wire. If it is burned open, it will act like a rubber band. Fuse link wires take some time to burn open, so a sudden and quick spark will not do it. Bolted-in fuses will blow right away.

The clue to either fuse device being burned open is to check for 12 volts on that large bolted-on wire on the back of the generator. It must have 12 volts all the time. If you find it is missing, everything else protected by that fuse will be dead too.
