Mastervolt Genny problem

[destiny]

Just bought yacht with Mastervolt "Wisper 6000" genny. It ran for a few minutes during survey. Ran for a few minutes after purchase, then stopped. Unit is 4 years old with 20 hours (twenty). There is voltage (12.8v) to the control unit. Pressing "glow" used to produce the usual whistle prior to start. Now it does not. Starter does not turn. I did have dud auxilliaries (7v), but the genny has own starter.
The unit ceased to run after I had it running, the battery charger "on", auxilliaries "on" and the turned the auxilliaries "off". Since then, its dead as described.
Any thoughts?
Many thanks in advance.

on your genny there could be a fuse blown or wire loos check all your wiring sounds like main circuit from the generator battery off has a problem , i had the same prob and the connector on the main 12v fuse was off, fixed it in 10 min of something i thot would take hours!! dont look at the 220v circuit there is nothing wrong on that side normally
