Well the new led headlight is nice and bright, but it seems my charging system has taken a dump again. I installed a new Rick's rotor thinking my old one was flakey, but no dice. I checked the brushes and had full battery voltage from both the OEM and aftermarket regulator, but no charging. No headlight either. Then I pulled the plugs and started component troubleshooting. The diode test seems to be fine, but I had a few weird things happen. Once while idling with my boost pack attached, I disconnected the regulator plug and the headlight switched on. I disconnected the plug leading to the alternator and checked the white leads. Zero ohms to ground. Aha! Crapped out stator. I pulled the leads out the left side of the bike and measured. Now all 3 leads showed the proper phase to phase resistance and no continuity to ground. Well that's weird. Perhaps it is chafing on the frame when it's in position. Sure enough, when I put it back, I once again had continuity to the motor cases and frame. Then I realized when I pulled the wire out the left side of the bike I was also disconnecting the yellow lead to the headlight relay. I put the alternator lead back in place and disconnected the wire to the relay and presto, no continuity to ground. Testing the wire going to the relay got me continuity to ground. So, should there be a circuit to ground through this wire? I suppose if it triggers a relay it must supply power through a coil to ground to trigger it so there must be some resistance value.
On top of this, when I attempted to charge my agm battery my smart charger gives up with an error message, so it looks like the battery is no good either. I have a spare lead acid that I put in hoping maybe an internally shorted battery was the issue, but it did not fix it.
I'm running out of ideas. I was thinking of buying a 3phase regulator off of Amazon to eliminate the stock regulator to take it out of the equation but I'm not convinced it is the problem, although the headlight coming on when I disconnected it seems fishy.
