I am troubleshooting a Paguro 6000 Genset with a Lombardini LDW 702 MG.
will not come up to speed and as a result the Output Voltage is low (around 170 volts on a 230 V genset). The generator
does not really struggle to start but rather slowly (5 seconds)comes up to arrive at a constant and steady RPM
and stays there. There is no smoke visible in the exhaust
. There is no knocking and the engine
does not seem to be running hot (though I haven't allowed it to run more than 10 minutes. There is no load on the genset whatsoever. It does not run erratically at all, just slow, as if there is a very large load on it.
I should mention also that when the problem began I had a separate 20 kW genset online and I started the Paguro before turning off the other, yet I had definitely not brought the Paguro online (commutator switch was in the off position) so I don't think there could have been a problem with one genset damaging the other.
Just wanted to get some other opinions if possible before I start taking things apart. I personally suspect either the governor spring or a block in the fuel
system... any suggestions would be greatly appreciated. Thanks.
