Hello guys I know this has been talked about a lot on this forum. I have reviewed all treads and have done what have helped others but with no luck.
Boat is a 2006 340. Gen has 115 hrs on it. Generator is throwing a LOC and shutting down about 15 seconds after full RPM is reached. I understand there is a time delay to allow water pressure and oil pressure to build.
I have installed new impeller checked water supply to strainer and out to exhaust thru hull. I have installed new water hoses through out. Removed heat exchanger and Back flushed. Removed fuel module and checked for build up. It was clean as it fresh water boat. Pressure tested fuel pumps.
I have tested water pressure sensor with continuity and confirmed it normally closed when not pumping but will open when gen is started for the 15 seconds. I have burped coolant side using bleed plug. I have removed wires from sensors jumped together every combination I could think of. This generator does NOT have the optional HET switch on exhaust with uses the same loop at the lwp switch.
Checked all connections, checked PCB board for corrosion and replaced K5 relay in the located beside the SCR module.
This generator has a 2 wire plug sensor under the coolant side close to LWP .
Has a single wire temp switch located on the opposite side of the engine near the front.
There is something causing this LOC and I have over 20hours of troubleshooting in so far.
Runs great before shutting down
Any info or help would much appreciated.
Thank you
Ryan
