Here's a pic of the starter relay:
The gray wire from the alternator is only about 10" long, then it changes to a heavier gauge (maybe 8ga) black/orange stripe wire with heat shrink tubing with "fuse link" printed on it.
There's no fuse inline between the starter relay & the alternator, just the short gray wire. There's not a fuse between the battery & starter relay either.
The F shaped connector connects to both terminals of the starter relay.
I haven't had time to remove the split loom from the wires connected to the F shaped connector to see which side each wire goes on the relay. There's a small (10ga or smaller) wire that goes to the battery & a larger (4ga) wire that goes down to the starter.
The alternator I'm looking at claims to output 110 amps @ 800 rpm (idle) and 200 amps @ 1600 rpm. They recommend 4ga wire, but didn't specify where to connect to (battery vs relay) It's about $200 shipped.
I'll drop them a message before I buy to see if they have any additional info.
Hopefully they don't have a core charge either.
