here's one for any serious mechanics out there...
we have a little 5Kva built-in diesel generator
. this is a MASE IS 5.0, which has a yanmar
L100 AE single
cyc diesel engine
. mainly runs watermaker
but handy for other stuff too
new in 2003 but only 1235hrs
has always run like a swiss watch until recently. fired up after a service
and find it won't hold revs under load - apply more than abt 2 amps load and bogs down so badly the output current
originally thought fuel
supply but checked this VERY thoroughly (inc replacing elect fuel
pump) and no problems there.
also checked alternator
and no problems there either
starting to think the problem is the governor. this is in 2 parts
- an external speed control & the internal lever assembly. the external speed control has a couple of springs which we're going to change as soon as we can get them. after that : running out of ideas (short of dismantling the engine
and checking the internal lever assembly)
anyone with any relevant experience ? helpful suggestion desperately needed !
