The day that Irene came thru, I didn't lose grid power as such, but did
have a series of outages that lasted 2-3 seconds apiece. Unfortunately,
these were enough to kick on the generator, only to stop a few seconds
later when the grid returned. And so it was on, off; on, off; on, off .....

So now the generator's broken. Battery won't even try to crank. All I get
is a grinding sound. Battery charger still shows a green light, so I
assume that a connection(s) has come loose or some sort of fuse blew.

Any ideas? Also, can this type of thing be fixed by an electrician? I do
have a service contract with the co. that installed the Kohler, and they
really know their business, but they are severely swamped with repair
tickets, which is understandable. Finally, can the automatic transfer
switch be adjusted to keep the generator from kicking on until grid power
has shut down for 10 seconds or so?

Thanks,Jack
