charging problems
I started the '98 Ultra and was getting ready to ride. Then, I noticed the system was not charging according to the fairing gauge. I just rode yesterday for 100 miles with no problems. Strange how something could quit while just sitting there.
The stator checked out ok with no continuity and it was less than 0.5 ohms.
The AC output at idle was about 10 VAC where it should be 19-26. However, at higher RPM such as 2000, then it is charging.
Last charging problem I had was when it would not charge at all. The culprit was the stator shorted out. This time is different.
I've replaced both items about six years ago with Harley OEM with about 20,000 miles since.
So, what's going on....stator or rotor? I'll check the regulator later as the load tester is at a friends house.

With the Fluke multimeter....I am showing 12.37 at idle. Increase idle, and the volts increase accordingly up around 14 or so. This does show it is charging...previous tests already confirmed this.
The battery could be a problem....probably closer to fours old now. Only the load tester can test this accurately.
It still didn't pass the AC output per the manual.
I'll know in more in a day or two.

You'll have to do an open and a grounded stator test to know more,I'm not sure of your year as a few readings are different.

Sounds like the fairing gauge is faulty.
Stator should put out 20v a/c per 1000 RPM.
DC voltage sames about right.

Among browsing the internet....Wondering if this could be applied to the EVO EFI models as well. I know I've gone through several stators with my Ultra and they were all Harley OEM.

I'll be getting back my load tester from my friend either tomorrow or the next day. I'll have a better check on the battery at that point.
