I've been having problems with the ignition fuse burning on my Vinson. I was curious to what the maximum voltage the battery should be reading while the atv is running? Mine is spiking up to 14.30 with it running.

 

Not familiar with the Vinson, but it's ok to be in and around 14 volts while the motor is running. Thats what most electrical systems need to charge the battery and run the lights, ect. Now if you were up around 16 volts, then we would have a problem.
