This one is new to me, all was well until I changed the battery.
Also, the engine is showing a new tendency to stall when idling, when cold, and is slower to start, needing some throttle to get going.
Where should I start looking?
My, that is a puzzle. The VW diesels I had had a battery powered solenoid that acted as a fuel on/off valve, no hands on experience with Yanmars.
I can't think of why a new battery would effect fuel delivery unless you have an electric fuel lift pump? Perhaps you hit or dislodged a fuel line connection when installing the battery, allowing a minor air leak?
"Slower to start"? If your engine has glow plugs, maybe they are not getting enough current, maybe go over all electric connections to make sure they are clean & tight.
Once it is warm does it run properly? If so, it may be back to the glow plugs.
Interesting, let us know what you find.
