Decided to remove some oil to get level back to closer to low mark on stick. Leak stopped, gen running fine and also on close inspection of stick found someone prior had scratched a faint mark not midway between full and low but closer to low mark so suspect this was seen by a prior owner. Thanks for help and glad this was all it was.

The recent oil change i filled back close to the full mark on stick whereas I usually only go to half way between the full and add marks. Will watch and monitor as a rear main seal leak will mean that genset has to be pulled from engine room and only want to do that if convinced seal is the issue. Thanks for the response.

Since I had bought a new 22si as a spare i decided to put it on today. 14.07 at alternator and batteries and  13.75 at helm gauge in idle, cold. Identical to  Gonna go back to alternator shop and ask to revisit the rebuilt unit and adjust voltage regulator back to 14 volts and it will now be the spare. Thanks all.

Retested today. At  strbd. alternator terminal 14.81 volts at idle, cold. At strbd battery post 14.80 while running at idle cold. This was with minimal load on 12v system.

Two 4d battery for starting each engine. Have a seperated 4d house battery. Port bank is 14.07 at battery post idle, cold. Before starting engine with minimal load the battery banks were 12.7v strbd and 12.8v port.

Alternator shop says 14.8v no problem. I understand when warm the output will drop up to 0.5v but is 14.3 enough to damage an expensive 4d agm battery pair?

thanks,

tom

was measured at the alternator terminals and was not warmed up. The other engines alternator puts out 13.75 at idle cold. Is it worth measuring at the battery terminal when cold or just run it and then measure?

thanks,

tom
