I have read several different articles on batterys and I am looking to see what a good voltage is o9n battery after sitting a few days. Some say 12.5 and others say 12.6. I have checked my battery and it is at 12.5. Should I be concerned with replacing it before summer hits. Bike starts but does seem a little slower to turn over before it fires. Just don't want to get stuck some where. Thanks,KP
What HDDON said and if you dont have one buy a Battery Tender Jr. Use it when not riding. You'll be glad you did. Battery Tender - Battery Tender Junior Charger
Just checked after bike sat for two days after charging. V at 12.8 Started up with meter on battery and looked like it droped to 10.5. At idle shows 14.5 v and at 2000 rpm shows 14 v. when I took it up to 3000 rpm volts droped to 12.85 alittle further at 4000 rpm it showed back to 14.5 volts. I am usually riding around 3000 rpm. Could there be some sort of flat spot where I am not getting a full charge in that rpm range ?
Thanks for the input all. Wondering also would I get a diagnostic fault showing if something was wrong ? It is a 2004 fxdli
I would not rely on a DTC for this type of problem. A code won't help you at all because it won't tell you exactly what is wrong. The closest diagram I have is for a 2003. If yours is similar,, 1) Replace that circuit breaker with a NEW one & make sure ring terminals are clean. Or better yet install a Maxi fuse instead of a new breaker. 2) Later models have a dedicated ground wire for the regulator. If yours is like the diagram (only 3 wires not 4), make absolutely sure the grounding of the regulator to frame is clean & tight. If you do have a 4 wire regulator, make sure the grounding wire is clean & tight. 3) Make sure connector 46A-46B is clean and tight. 4) Battery grounding cable to frame (#70103-96) must be clean & tight. Also check Battery positive stud on the starter is clean & tight. If you still have similar voltage readings @ different RPM, cross check your meter with another meter.
