Voltage readings

Hey All! I am hapy to say that my baby is now rolling in fine style. I took her for a nice 30 ish mile (mostly freeway, 6k RPM 70 - 80 MPH ) ride today and she ran great, pulling at all RPM's with no hesitation. I did find one odd thing however. When I first started out, my voltmeter would run up to about 14v when accelerating / cruising at high rpm's. When I made my turnaround to come home, she pegged at 12v and didn't go any higher. At idle it sits around 11v ish, depending on if the brake or turn signal is on. From what I read when I searched this may not be normal and I should replace the R/R, correct? Following that, if the problem persists or gets worse, replace the stator? I want to make sure I do this right since the costs involved are very high, and this bike is pretty much for my wife and I to ride 2 up together, so it wouldn't be just me stranded. I can handle being stuck somewhere cause the wife has the truck, but if that wereto happen when we were both on it that would be problematic... Thanks in advance for feedback!

Remember that the regulator will regulate the voltage that goes into the battery. You might try using it for a while and see how the regulator is doing and see if the battery is holding enough power to start the engine.

Good point.

I was running through some other threads and found one where the poster had discovered that his wires had melted. I got to looking at my bike and found (behind the left side cover) a group of 3 yellow wires wrapped in duct tape. The tape looked pretty melted. When I pulled it away, it turns out these are the yellows coming off the stator and into the harness. The bullet connectors are nicely corroded. I'l post a pic after I pull them. I'm heading to Radio Shack to pick up some new connectors and also 3 inline mini fuses. They should be 15 amp, correct? We'll see what happens. When I started the bike back up last night to put her away in the garage, the voltmeter was again showing 11+ at idle and going up and down based on RPM, so the condition only exists when the bike is hot. We'll see if the new wires change anything. The battery is a MF and is about 1 year old. AFAICT, that's the only thing the PO did on the bike - he was the 2nd owner.

The best thing to do is to solder the wires and use heat shrink to insulate.
