Kohler Genset not producing ac power...solution

I have a Kohler 8K generator that started and ran great, but was not putting out any ac power.
I read about "flashing" the system to re-energize the magnetism necessary to get the power back.
$10 Solution...
I purchased a 12' extension cord from Dollar store and 2 ten amp in line fuses.I then cut the female end off the cord, added some alligator clips where the female use to be. I then cut the male portion off the other end and spliced in the 10 amp fuses on each of the wires. I used the 12 volts at the battery selector switch and hooked up the positive wire to the hot side of the switch and plugged the male portion of the cord into an ac receptacle on the boat. Started the generator and touched the negative wire at the other end to a ground on the engine and WA-LA ac power restored. It immediately blew one of the 10 amp in line fuses which was an indication that it worked.
Hope this is helpful to anyone else that may run into the same issue. So many forums state the issue to illicit help but seldom follow up with the solution that fixed the problem.

When you get a chance, could you post a couple of pictures? Great solution. We have a Kohler 8 kw as well.

Re: Kohler Genset not producing ac power...solution

Easier and safer to join the chuck of a cordless drill to the chuck of a 240 volt drill with a short ⅜” rod. Plug the ac drill cord into a socket and spin the drill with the battery drill, the moment that the field re magnetises, the ac drill will take over and the trigger can be released ( or the outlet turned off). Don’t use a big powerful ac drill….. no live exposed wires or fuses needed. This trick works about 50% of the time, the other times require flashing the field with other techniques and traditional methods (including a rheostat or variable resistor).
