Talking about my generation

[the village idiot]

Just wondered if any of you are familiar with the electrical side of generator sets?

 

I have a 10KVA diesel powered generator which has suddenly started only putting out 100volts rather than the required 230/240volts.

 

The yanmar engine seems fine so I seem to have an electrical issue.

 

I've tried changing the capacitors which had no result. My generator doesn't have an automatic voltage regulator.

 

The drop occurred when starting a second 2.2kw motor whilst it was running the first one fine. It now won't run either motor.

 

Apparently a new alternator is £2000 plus so I was hoping there might be something else I can try before writing it off.

 

Any thoughts gratefully received.

 

TVI.

Can't help much, if you need a man who can I'll ping you a number, he's just up the road from you.

When he fixes it let us know what went wrong. It sounds like one of the field coils isn't getting excited.

I think I'll be lucky to find someone who is keen to look inside the alternator. Advice I have received so far from more than one source is get a new generator.

 

This would be a shame as it has only done 2000 hours.

Things like this i love where 30 year of knowledge come in. Have you run a 110v tool off it ??

It may be cheaper to get a new one but the engine will still be good. The difficulty in reusing these  things is the alternator is built onto the motor and only has a bearing at the outer end making alternatives difficult to fit.

There is a far easier way if she is kicking out a good 110 v supply believe me and cheap. Bought a tow along compressor/ generator a few years back and used a step up transformer like in the link below, genny was only a 110 v ex gas board
