The patient- a KiloPak 12kW genset powered by an Isuzu 3LD1 3 cylinder diesel engine. 450 hours run time. All was working well on our last summer outing, with zero indications of trouble.
In December, I strung up the Christmas lights and then went to start the genset to test everything- but it would not fire. It would almost catch, but no start. I checked the water sep and spin on filter - all good.
On the control box (prime, preheat, start, stop buttons) I noted that the stop solenoid was not operating when the button was depressed. I pulled the solenoid and ran it to 12v direct- seemed to work perfectly. I pulled the fuel lines and confirmed fuel to the injectors.
I finally called in Hatton Marine, as they are Isuzu “experts” (I question the “expert” part…)
Hatton came in and ran essentially the same tests and wanted to replace the stop solenoid, as it was the problem…even though I stated I had tested the existing one and it seemed to test fine. I agreed to the part replacement, and after they installed it, there was still no start.
Hatton then declared that the injection pump was faulty. I sent the service advisor some info from BoatDiesel that showed the 3LD1 has 3 injection pumps. Hatton then compression tested the engine and stated that the genset was dead and needed to be replaced due to an average of 200 psi across all cylinders.
I’m open to ideas from anyone experienced with this type of problem…
