Hello All

I have a 09 ViVi Tour Premium.... I had electrical issues and after replacing the Voltage Regulator and 40 amp breaker (replaced on Spec) the issues seemed to be solved.

 

However, now I have noticed that the red check engine light comes on whenever the voltmeter goes high, in the red (approx 16+ v). this of course happens with power on the throttle. I read the previous posts regarding loose battery conections, so this was the first thing that I checked... all was good...

 

I am wondering if there are any other suggestions that people with this issue have tried...

 

thanks in advance for your help.

Gerry

Gerry,

I'm not the best when it comes to electrical issues, but I believe that your system should not be charging that high. The last time I replaced my regulator I used a less expensive aftermarket product. It worked fine for a short time, but then started acting up. I don't recall what the problem was, but after doing some research, primarily by checking the service manual, I found that it actually did not meet the OEM specs. After replacing it with an OEM regulator my problem was resolved.

Good luck brother.
