I haven't looked at the TM yet. I was just on here making a different post and figured I'd ask away. I have an 803A that I purchased over a month ago. It started and ran great. Yesterday I was going though my generators, started and ran this one....but it started and turned off and overvoltage light stayed on. If I flip up the battle short when it starts, it stays on....but the voltage gage is pegged at 300V. I immediatly shut it down and haven't done any trouble shooting yet.
