On my last outing, my generator shut down while cruising at idle. The error code was UU, which is undervoltage (I believe at the source batteries). It sat for a while then I got LOC error code, which is loss of coolant (no leaks or actual loss).
I took the impeller out and one vane was missing, so I installed a new impeller.
Generator started OK, but today after 30 minutes or so it shutdown again. The error code again was UU. When I got back to the marina, I attempted a restart and got LOC again. It cranks and tries to start, but shutsdown quickly after less than 5 seconds or so.
I can see water coming out the exhaust side, and there is coolant in the reservoir.
Any hints before calling the Kohler dealer or MarineMax?
Could the broken (missing) vane be stuck in the heat exchanger and that's what's causing a problem?
Could my batteries be bad and that's what's causing the UU code?
Are the 2 codes LOC and UU somehow related?
Engine starts and runs fine from the same batteries.
Thanks,
Esteban
