NextGen Shutdown

[Jfrano]

Don’t use the generator much. Humid day in NY, running generator for AC. Every like 15-20 minutes would shut down. Anyone else have similar problem?

Thanks

Did you get an error code? Were you using it while cruising? Sometimes at a higher speed you may loose prime.

Where would the error codes display? We were moored . I had all panels enabled both
Both AC running, hot water heater and Cockpit ice maker on.

I had similar issue but probably different cause. I recently replaced the faulty electric control valve for raw Water to generator. I replaced with a manual valve. Not sure I got it tight enough so I think I have air being sucked in which makes it cycle down approximately every 10 minutes. Going to tighten and see if that does the trick.

I have been working on the same problem for four months now. One thing I learned was to never have the hot water heater on unless on AC power. The generator is just not big enough to handle that and A/C.

A couple items I would check.
Fuel lines tight and no air in fuel system. Fuel filter clean and water free. All fittings, hoses, clamps, filters, pick-up tubes etc. should be double checked to make sure absolutely no air is entering the system.

A different issue would be air temperature in the compartment. The small diesels require good ventilation. The ventilation systems in Rangers is marginal at best. If it is a warm day and the main engine has been running and then you start the generator confirm you have good air flow from the ventilation blower. This should pull cool air into the sound proof enclosure and exhaust the air out the hull ventilation exhaust vents. Try opening the engine hatch to see if this extends the run time. If so install more compartment ventilation for smoother engine running during higher ambient temperatures.

Issue was related to load. Overload apparently causes the generator to shut down. Ran for 45 minutes no problem with 1 AC engaged. Then turned on all the breakers. Then with both AC going , the Water heater and ice maker engaged as needed, the unit stalled in 10 minutes. Then turned off ice maker and water heater and unit ran for 30 minutes fine.

I might try engaging only the ice maker and wAter heater to ensure unit doesn't stall, otherwise perhaps an issue with one of them.

I am very aware of power management both AC and DC; with a small generator and limited battery bank. I have the DC side down fairly well, but its the output from the Mase 2.7 generator that is a conundrum. Max continuous output according to specs is about 1900 watts. So what kind of a meter can I place to read the watts and prevent the shutdown? Where can I place the sensing unit to read the output? Is there a device that can warn me of the impending shut down so I can turn off some power-robbing appliance before the generator arbitrarily shuts down and stops everything!

Thanks, so that appears to Be the limiting factor.

After my unit stalls and I attempt restart, it goes into an extremely rough idle and I can NOT shut the unit down. I learned to remove the generator cover and pull the throttle cable and the unit runs normal. I can then Turn off via Cave switch.
Do you observe this behavior after a stall?

Thanks
