right engine 4lha ste not running right
I recently took my 390 with twin yanmar 4lha ste out. I noticed that I had no volts indicated, low oil pressure, low engine temp and the engine lagged behind the other (starboard). I came back to the marina and shut everything down. I waited a few minutes and started both engines. Both are now running perfectly! What kind of issue did I have? My boat is a 2000 so they are not electronic. Seems electrical. Alternator is putting out volts and fuel solonoids are ok.
