Hey all, it's been a while.... hoping y'all are doing great! And hoping someone has some knowledge of my generator
It's an old (30 y/0) Onan 6500 marine
genset in my amel super maramu. Symptoms are: gennie holds loads fine up to about 2000 watts of demand, but much above that (but well below 6500) it will cut out the production of power
for a minute, the engine
speeds up as the load comes off, then in a minute or even less, it cycles back to engine
under load and the watts coming back online. So it works to a point all day long (at half load or less) but then will cut totally out and back if I put too much load on. The engine side has been serviced/rebuilt last year.
What can I look for to see why it can't handle even half it's rated load? Mech/fuel side possible? The filters were changed last year too. Voltage regulator
? Motherboard thingy? The local mechanics want to pull the whole thing to fix whatevers wrong but that's a huge job here and I'd rather wait or replace it if that's the case.
Any thoughts would be MUCH appreciated!
All the best
