This has happened a couple of times to me lately.
The voltage gauges drops all the way to the right, which I think if I read the gauge correctly means that the voltage has dropped off to almost nothing. The truck begins to miss worse than it already was.
Any ideas? Is it a short somewhere?
Is there a voltage regulator on these trucks or is it part of the generator?
Last time it happened it eventually came back up, yesterday I shut it down and it still had not come back.
