I should be so talented!
I've removed and cleaned all cables between battery and starter. Not an issue. All were clean.
I've removed clutch switch and checked; seem fine.
I have not checked side stand switch yet, but that's next. I doubt that's the issue since it seems that it must
be directly in the starting circuit because of that one symptom..... the cluster (particularly fuel gauge) goes blank as if the battery was disconnected.
Low compression would not keep it from cranking and would not cause cluster to blank.
Seems as though it's gotta be either the relay or starter, and I'm inclined to believe relay. A bad starter usually is bad when engine is warm, not cold as the compression is higher.
