Wink Generator failure.... or just a little sick !!


hi all

this is my very first question and not sure if i am even in the right place to put my question to the forum.

Hubby and I not long ago picked our vessel up from the freighter in Brisbane and while it was in quarantine we had the generator going all day with no problems.
now when we go to start it ..... it starts perfectly and runs perfectly for approx 15-20 secs and then shuts down.
Hubby has checked that there are no wires hanging off and that there is enough fuel going through..... and that the filter is fine and have checked that there is enough oil etc....
Does anyone have any suggestions ?

thanks
Jenny

Which one do you have? Some gens have auto shutoffs for oil level and/or coolant temp. These may be the problem or the sensor is giving false indication. I have to reset mine every so often, by disconnecting the start battery and letting its messed up computer brain reset.

Need more detail to help with a real problem.

Jenny,

Kind of a stab in the dark (since you've not given us much to work with ), but if it's a diesel genset then I'd first suspect there's some air in your fuel delivery system. Try bleeding the system and see if that solves your issue.

Thankyou for replying to my probs..... Sorry about the info.... It is an Norpro 14.5 kw with an Izuzu engine.

Hubby has bled the fuel line and checked oil etc.... there are no wires hanging off ... It is a mystery....

Those do have automatic shutdowns. Could be malfunctioning.

It sounds like your husband has covered the main faults. As well as taking Minnewaska's advice on checking an auto shutoff, I'd still be looking at the fuel system. I would run it off a separate container of fuel to troubleshoot it further. I've seen this symptom a few times on highway trucks, a motor running for just a short interval when there was some sort of a restriction between the motor and the tank. The motor starts up and runs, the restriction causes fuel starvation, the motor quits. When the motor quits and you go to start it again, the fuel pump delivers just enough fuel to get it started again before it starves out again. I used to pour some clean fuel in a coffee can or something and run the motor off that to see if the problem goes away. It could be anything like a degrading hose between the motor and tank or something funky going on at the fuel pickup in the tank. If it runs off your alternate fuel source, you'll know the problem is between the tank and where ever you plumbed the alternate fuel source into.

What you describe might be an over temp shutdown.

I assume the genset is water cooled. Is the seacock open? Is there good water flow from the exhaust? Is the radiator full of coolant?

If there is a raw water flow sensor, those notoriously go bad.
