Yep! Somehere in it's past, someone who had little knowledge of wiring other than continuity did some massive fiddling with the harness.
Splices crimped, not soldered, then wrapped with duct tape!
A main 10 ga. ignition wire reduced to 14 ga., then down to 18 ga., where an inline 20 amp fuse was wired to the starter relay, without benefit of a fusible link!
Three crimp splices within a 6" run was commonplace.
Surprises galore!
And all of this wonderment was deftly hidden inside a nice wrap of electrical tape, mimicking an actual wiring loom!
I'm surprised it ran at all.
