Pto generator not working... Pls help?

[PILOON]

If it is a true 'generator' and not an alternator then perhaps the field coil needs to be 'flashed' as was commonly done on older cars B4 alternators.
Alternators and generators work on the principal of magnetic fields being interrupted by a moving coil.
To retain magnetism occasional operation is required.

Just got home and read the emails from the company. There is a fuse inside the housing. It doesn't mention this in the manual.
I took the housing off, looked and sure enough, it was blown. They put a spare inside, so I changed it and it started to work.
I didn't get a chance to test it for long and put it through it's paces. That will have to wait for a couple of days.

The fuse was a 5x20. I can't tell what kind of 5x20 so I have emailed the company.

I'm not sure what caused this. If I overloaded the generator, shouldn't the breaker blow in the housing?

Thanks for everyones help

This is why so many generators fail. Breakers only come in certain sizes, for one. So you pick the NEXT highest size. Then, you must allow for motor start currents, which isn't what the genset is capable of in continuous duty. So it is possible to run the genset way over it's capacity to destruction.

It is a good idea to have some way of knowing your loading.I use a stand alone UHF (wireless) EFERGY energy monitor which has been great for this purpose. Even has alarming capability, although awkward to program.

5x20 is a 5mm by 20mm fuse, used in alot of test equipment and other things such as auto power plugs and some on board fuses for amateur radio equipment. Radio Shack used to carry some values.

Do not think they make bigger then maybe a 10 or 15 amp max so it will be located on the AVR control board

Something made it blow, now find out why?

I think sometimes the fuse itself is just bad. I have had it happen.

I am guessing from age, poor quality, possible poor qc, moisture or vibration.

If you can clearly (on larger ratings) see the metal burned through or it is blackened, there probably was an event.

Nope, it was generating then quit

A time delay fuse of the same rated amperage prevents many phantom fuse failures.

Thanks for all the help. I'll post this in case it helps others.

So after having discussed this with the manufacture, who was great, I have found out that most likely what happened was that there was a sudden momentary draw of power that the tractor couldn't produce which caused the fuse to go. (He is not sure, but that scenario... if I have described it right, could blow the fuse along with others mentioned on the board.

You can't see the fuse, You have to remove the metal housing (6 screws) and

This is a fuse on the AVR board itself.
The fuse should be 5x20 3.15A

I have it up and running, just haven't had time to give it a full run for more than 10 min. Will do on my next days off
