Voltage regulator

My 07 Custom's check engine and battery light came on while riding today. I checked the code and it came up voltage regulator. My question is, would it be okay to ride it to my local indy to have them check it out? Bike runs fine and i just changed the battery. Thanks for any input.

You'll be able to ride it as far as the battery's charge will allow you to. Once it's depleted, you're going to be on the side of the road with a cellphone in your hand.

The VR fault may be low voltage or high voltage. Measure the voltage at the battery if you can with the bike running. If its too high, like higher than 15 volts, you could damage your new battery by overcharging it. It should read about 14 volts. I think a diagnostic fault appears at 16v.

In a low voltage issue, you have to eliminate the stator before moving to the VR. If the voltage is too high, it points to the regulator.

Just replace the regulator with a Cycle Electrics.

If it fixes your problem they you’ll save a Dealer service charge and you’ll have the best aftermarket regulator.
If it doesn’t fix your problem at least you’ll have the best aftermarket regulator.
