[QUOTE="RadioHowie, post: 1167222, member: 426"] Tom, from what the OP wrote, he was seeing 14.02v at idle after the the harness install... That pretty much eliminates a stator or R/R problem. 14+v is exactly what he SHOULD be seeing at the battery. The fact that a load is drawing the voltage down immediately indicates either a bad battery, or an improperly charged battery. 12.8v with the bike off definitely points to an under charged battery. It should be more like 13.7-13.9v Remember, all the troubleshooting in the world isn't going to make up for a bad or under-charged battery. You can't ask for better than 14+v from the charging system at idle. After villajuan81 gets home today and re-checks a fully charged battery, we'll know more. If the input at the battery terminals is still 14+v, the charging system is good, but if headlights or other loads drop the voltage down to the mid-twelves, then he's got a bad lump-o-lead in the upper cowling, even if he DID just replace it recently, as indicated in his very first post.
