Hi all, I recently noticed that my Autometer volt gauge will peg at 18v as I'm driving then return to the normal 14.3 for a while. It has been doing this every few minutes so it is reading 18v about half the time. I'm thinking it's the voltage regulator going south, what do you think? This is on my 70 bee that runs an MSD electronic ignition and the 3 pin electronic voltage regulator. thx
