Well now...my bike would not start this past weekend, after a 6 mile ride...I briefly turned the bike off, & on restart got a s-l-o-w partial crank, followed by the dreaded click-click-click-click. Damn.

Called the wife to bring a jump pack. At least it was a nice late afternoon while I waited.

When I got the bike home I swapped in a new, fully charged battery. The original battery was over 7 years old, so no big deal, right? I mean, not everone can have the battery life of Ian

Well...I expected to have some joy, but no...over 3 grand voltage was falling off into the 12's. Bummer.

Sooo...I checked the various charging circuit connectors (stator into main harness, R/R, fuses, & other readily accessible connectors), checked the main ground connection, checked stator resistance (infinite), & all appeared OK.

That leaves the regulator as the prime suspect. I'm going to order a replacement, probabaly a Rick's mos-fet. We'll see.
