My 545000 Powermate has been used about 600 hours--either as backup to rural electricity outage, or for Ham Radio Field Day on day a year. This year after about 8 hours of operation it quit. The engine runs beautifully, but no electricity. Can this be a frayed wire? I have not grounded this generator. could this be a problem?

Sounds like you need an Uninterruptible Power Supply (UPS). They will keep the fridge running for about an hour with no power at all and they also protect against brownouts, dirty power and surges.

This is for 545005 but I hope you'll find it useful. http://www.powermate.com/pdfs/2007/11/16/manual_pc0545005.pdf

Does it have a puel pump? I know the Briggs motors have a fuel pump works of piston vacume

What is the age of the unit? Those batteries don't last forever and are constantly under a small charge. When the outage happened the battery discharged and the sensing circuit was able to tell that the battery was no longer any good.

That sux! Thats NOT acceptable in any way... Take it back and demand it gets repaired.. With devices such as this it is not the simple passing of time that ages it, but the actual POWER ON time... & Yes if Overloaded it should simply have "Tripped" a breaker or the like.
