Hello All,
Had a bit of a bad electrical weekend. Hadn't used the boat in a few months, so went out to spend the weekend on the hook. Turns out our hose bank had gone south since the last use.
Anyway, when we shut down the engines anf got anchored we immediately started getting low voltage alarms, so I started up the gen set and turned on the battery charger, a pro mariner 50 amp charger. The water heater was also on. Almost immediately the generator started surging and then shut down, throwing off an OU (over Voltage) code. Started it again and this time it shut down and gave a OS (over speed) code.
I realize it was mistake to try it again.
Started up and came back to the dock. Did some trouble shooting. The charger was pushing over 50 amps non stop and the house bank was not taking a charge. The marine electrician here at our yard came over and took a look. He recommended replacing the bank ( I had my suspicions about it anyway) and the charger. I did both. The charger was under warranty.
Gen set will start, run for a few seconds, then shut down with the same OS code. Both the electrician and I feel like it is a failed sensor switch, but I'm just an owner and he is an electrician not a mechanic.
Anybody got any advice on where to start? It does not seem to be running fast. It shuts down with the main breaker off. It is a Kohler 8KW, 8EOZD.
Thanks.
