I have a 96 S1 thats not charging the battery. I ran all the tests from the manual. I checked the stator and it passes. When I stick one test lead in the stator socket and the other to a good known ground I show no continuity. (PASSED) If I put each test lead in each stator socket I show .03 ohms. (PASS) If I start the bike with both leads in the stator socket I get 41v AC. The manual says between 38-52v. Everything passes the stator tests. I did the VR tests too and they all passed. Because I have one,I took the VR off my M2 and put it on the S1 and no improvement. Also my wiring is all in GREAT condition. (3800 mile bike) Testing the battery after I pulled it from the charger showed 12.8v (not running). When I start the bike and rev the motor the volts from the battery are not increasing. I'm assuming the rotor is shot. Also, if I'm going to be pulling the primary to change the rotor, should I change the stator while I'm in there or go by the motto ''If it aint broke, dont fix it'' Whadda you guys think? Sound like the rotor is bad? (Message edited by akironic on July 15, 2008) | ||

The rotor is but one suspect. The battery might have internal resistance and cannot hold a charge. If you can, try substituting a known good battery. However, there's one more test to do on the stator. Set up the test like you did in the first test above only put the meter on a higher ohms scale than RX1, like RX1000. If it does not still read infinity, I'd say the stator is toast. Also, there was a factory mod when replacing the battery which included a new mounting place for the voltage regulator. If your VR is mounted with the fins facing to the right side instead of the original position, straight up, you are good to go. Just make sure the VR ground wire is making a solid ground connection to a clean spot on the frame. One more thing to consider is that as these bikes get older, the wiring insulation tends to get brittle or fracture, exposing the wire inside. Normally this may not be a problem when the bike is still, but when running, vibration could cause intermittant shorts where a wire is exposed. So even though a component may pass a static (non-running) test, it may fail when conditions are dynamic (engine running). | ||

Sounds like a battery to me. How old is the battery in there? | ||
| Akironic |
The battery is brand new in there. I got it fixed though. It was the voltage regulator  | ||

OK so was the replacement from the M2 bad also or just the wrong one??? | ||

Apparently all it takes is a quick spark to the VR's and there smoked. When I took the one off the M2 I didn't bother disconnecting the battery. I accidentally touched it on the frame for a millisecond and that was all it took. So now I had to buy 2 VR's.  | ||

Hey thats very cool (well not for you) but I learned something today. |
