Battery on my 97 M2 cyclone isn't charging. Both the battery and VR have already been replaced, gone through most of the wiring I could think of looking for shorts but have found none. Next step seems to be replacing the stator but would rather not waste the money unless im certain its shot. Going through Reeps diagnostic post I got the following readings: Starting out with bike off: 12.65 V across battery While running dropped from 12.34 to 12.33 @2500 for ~1min Stator pin resistance to ground ~infinite Stator pin to pin ~ 65 ohms Stator pin to pin running: .223 idle to .245 VAC @2500 VDC out of single wire from VR while running ~2-8 V From the low output on the stator pins while running I'm assuming its bad, but shouldnt the pins ground out when testing for continuity? Also the resistance from pin to pin seems rather high. Rather new to the motorcycle maintenance world, and have never dug into the bottom end, how difficult is it to replace the stator? Go with harley replacement parts or is there a cheaper/better aftermarket out there? Also, would trickle charging the bike overnight then driving the 30miles to work and back harm the bat/vr/stator until i get it fixed? I appreciate the help, Whosull | ||

Sounds like a bad stator. The pin to pin resistance is way too high, and the voltage output is (duh) way too low. Pop off the primary cover and give it the hurl test. Take a deep whiff... if you feel like hurling, then its clearly a bad stator. It probably broken then shorted wire to wire in the stator windings somewhere in some sort of foul bubbled mess... so you get a pin to pin resistance that is wrong, and no ground faults. The real proof is the output though. If you are measuring pin to pin and only see some fraction of a volt, the stator or its associated wiring is clearly toast. | ||

Wanted to give this post a bump.. dealing with the same thing on my 2000 M2. slightly different readings but same result. pin to pin is to high (1.8) and output is rather low (4.5 ish) and batt sits just over 13v while off and just under 12 while running.. But I was hoping to get a response for the second half of Whosull's question.. " Go with harley replacement parts or is there a cheaper/better aftermarket out there? Also, would trickle charging the bike overnight then driving the 30miles to work and back harm the bat/vr/stator until i get it fixed?" Any info on this would be a help! Thanks fellow Buellers. | ||

If you run the battery until it dies, then yes, you are hurting the battery. The less deeply you cycle them the longer they last. But AGM's aren't as bad as other chemistry in this regard, and batteries die for lots of (other) reasons as well. So if you want to take a ride, take a ride. You could unplug the headlight during the day and get a LOT further. That's where most of the battery power goes. 30 miles would probably be an upper bound, it's probably about how many minutes your battery can run the lights, not how many miles you go. Get the lights out of the picture, you might be able to go for hours. Dave Barr went half way across Siberia that way. |
