I attached a picture of the diagnostic codes on my PV. The voltage seem to be running a little high on my Voltmeter gauge (15+) before it the engine & battery light came on. When the lights came on the voltage on the gauge dropped below 12 volts. I have a regulator on order as of today. My question is the other codes in the picture lead me to believe I might have issues with the radio control switches. Has any one seen the DTC’s come in with low voltage?

 

if the battery is good fix the regulator then see if the codes come back.

 

The B codes shown are historic, do they come back once cleared?

 

I will monitor it once the regulator is changed out. Thanks

 

FYI.... there was a product program on the 2012 Harleys, as the MoCo got a batch of bad Voltage regulators...

It was announced in Service Bulletin #M-1325 dated June 11, 2012. It announced the Product Program 0912....

Basically while you were still within factory warranty, if your Voltage regulator fell within a certain date code, it would be replaced for free... Had to have mine replaced during a cross country trip in 2012, as my voltage started fluctuating.

It's possible you have one of the bad regulators, that wasn't replaced under the program.

Too late to get it replaced for free, but if you are interested, here is the info on the date codes affected... you could check just to see if yours is one of the affected regulators...

 

Doesn’t look like mine was in that recall date code. 1812
