Thanks for the update. Good reminder that one of the first things to do when you have such problems is to clean all the battery connections.

One bit of information to other Yanmar owners is that they are noted for having a starting problem if the cable run from the engine to the panel is too long. Voltage drop to the solenoid can cause an intermittent no-start issue. The solution is to add a starting relay in the circuit. Any Yanmar dealer can help with details.
