Hello,

Recently, I have been experiencing what I would call "voltage drop off" when riding at higher RPMs. What I see is the voltage gauge will be steady at a little above 14 volts and it will suddenly drop to approx 12 volts for about a second until it "catches" and returns to normal. This takes about 2 seconds to complete.

It is a 2000 Ultra Classic.

This only happens at engine RPMs above about 3400. At night, it causes the lights to flicker a little bit at the voltage drops and returns to normal.

I have recently had to replace both the stator and rotor (loose magents) with true 45 amp parts. This was done approx 2000 miles ago. About the same time, I replaced the factory headlight and spots with Kuryakyn LED lights and these (by spec) use almost no amps. So, the charging system is not having to make as many amps at any given time as it used to.

It is time to replace the voltage regulator? Has anyone else experienced this with LED lights that have almost no amp draw to them?

As recent as this afternoon, I was coming home at approx 3500 RPM and I could see it happening a whole lot more than it used to and my fear is that is will simply stop charging one day.

Any suggestions? Thanks to all in advance. Please excuse me as I'm new here.

 

There's no "time" to replace the regulator, If you've checked all you battery connections and ground to frame connections. Then the voltage regulator might be your next step.

 

The battery connections are all good. Actually, it was nice to no corrosion on them at all. The grounds have been checked and tightened too. I did this when I changed the battery last July. All seems to be very clean and it order.
