500c dyno putting out 20 volts!

Fried my tach converter a few miles after install, checked the voltage at the dyno .... 11-20 volts, depending on RPMs.
I can't imagine this is normal, what do I do to fix it?

Worried I'm going to damage my electric fuel pump/distributor. Unsure if this is new or has been this way for a while.

Thanks in advance.

Hey, do you still have the mechanical voltage regulator? Most likely that. Whack in an electronic one and no more worries
