    air conditioners stop working on offshore trip on 50 Post with 15 kw westerbeke running but it seem to be surging in rpm. Anyone know what problem is?

    Could be anything based on the description. Have you confirmed water flow? No water will cause compressor to increase current draw and load up the gen. Are all units doing the same thing? If so you probably have a common water pump.

    All the units stop working (3) and each has separate water pump that is clear of debris so it’s a power problem of some sort associated with the generator.

    Then I'd suggest you start with the generator, start one at a time and see if the Gen starts to overload. Watch the ameter on the panel so you can measure increase load.

    You need to start by defining "stopped working"

    Do the air handlers work, do you have power on the controls? do the breakers trip? How much voltage do you have on the panel? You said the generator seem to be surging, how about frequency? If rpm varies on a generator it will affect frequency not voltage.

    Need more details. We re not psychics.

    After what pascal said. The first thing I’d start with on the generator is to change the primary and secondary fuel filters.

    Hi on our 12.6 there was a faulty electric governor sensor that caused ours to hunt very bad, this may be the case with yours.

    Thanks everyone for your responses. I’m fairly sure that the generator is not producing the right electricity and the 3 units don’t like it and turn off Will ck engine details and then electricity details of generator Have an expert coming to ck it out. Again thanks
