Clink the link watch the video The voltage gauge is jumping. What are your thoughts? I observed normal voltage at idol, and the next day it was an hour on the highway before it happened.

Voltage regulator.

 

Remove the seat and connect a volt meter to your battery. Use one with a needle gauge. Start your bike and check see if the needle jumps on the volt meter also. If it doesn't, then your problem is with the gauge. Maybe a bad connection.

 

Ran into that same problem a couple years ago. Mine however went much wider swings and then voltage over all just started dropping.

It was the plug coming out of the stater from the engine into the voltage regulator (vr). The contact sockets were not circular enough to make complete connection to the vr. When looking into the rubber of the back shell of the connector. I saw that the contacts were discolored from a shiny brassy look to almost a burnt dark look. And the distortion of the electrical contact it self was giving the appearance of a "C" vice what it should look like as an "O".

I think the discoloration on only a couple of them was due to heat build up on the contacts from only two phases that maintained enough contact onto the input end of the vr and they took the load and keep me running to get home.

I was on a road trip out of state when I found the volts gauge going nuts and it was cold weather so the wife had her heated gear on and up! Also blown out the face plate of the radio but the bike kept running.

Since the back shell is rubber, I took some fine needle nose pliers and reshaped my connection socket contact back into an "O" again. Cleaned all the discoloration off with gun cleaning wire brushes and also cleaned up the contact pins on the vr. Re-assembled all with good silicon dielectric grease and never had another issue again.

Any time removing the vr since I re-inspect for the rubber socket ends on both input and output for spreading into those "C" patterns again, and not have had any since. All that I can figure is this is a MFG issue that has never gained enough support for a TSB and I know having read a bunch of threads of burnt out stator assy's its costing many a bunch of money.

Again, I have paid myself back in installing the voltage gauge on my Road King, Dead Center Cycle fairing, in not having to change out my stator assy!

All that have Volt meters hope they keep an eye on them!

IMO its time to check the entire path on yours! Something may just be loose!

 

I found the problem was my Hogtunes amp. I disconnected the power to it and the problem went away. My amp was acting up before it and now it's totally screwed. Will have to order a new amp.
