My 91 Heritage stranded me at work last week, after getting her home, I put her on the Tender overnight. Next day all was good, multimeter showed 12.7 vdc in the battery. The previous owner had installed an aftermarket long dash, and the light divider was hitting the wires for the ignition switch, thinking that was the problem, got that settled, fast forward a few days a acquaintance came over to see the bike. I flipped the switch, pulled the choke, tapped the starter button and nothing. Put her back on the Tender, next day the Tender showed green light, put the multimeter on the battery 12.7 vdc good to go. Fired her up, metered the battery again, 12.5 vdc uh-oh, brought the rpms up with no change. Battery was installed in Oct this year, the stator/rotor was replaced by a dealer shortly before the bike was parked, no mention in the paperwork of replacing the regulator. I searched the site and found the “Testing the Charging System” sheet, here are the results: 1-Battery test-charged and load tested by a local auto parts store shows good 2-Charging system voltage test-12.5 off and same idling and at higher rpms 3-Connections-all inspected, cleaned and greased. 4-Stator/rotor tests AC output 22-23 at idle, increasing with rpms Resistance .8/.9 ohms Ground test shows no continuity to ground 5-Regulator test Diode test + lead to AC and - to charge wire shows .45 vdc swapping the leads shows infinite Ground test shows good ground to frame I was thinking regulator, but now I am not sure after the test. I was searching and found mention of the Cycle Electrics regulators, I found a couple of places that have them for about the same price as I can get the OEM from the dealer. Any one have experience with them? I could not find much on the web in the way of reviews. I also read that some are installing a dedicated CB or fuse in the wire from the regulator to the main CB. Good idea or not, if so what amp for the CB? Thanks for reading and any help appreciated!
