4500- 1969 model Fordgenerator/regulator identification help

[Ronald Wright]

Well, the generator is working great after getting new brushes and springs installed. The problem now is NO regulation of voltage output.

Generator: Lucas 22756H 37 72
C40T 12V

Nothing identifying if it is 11amp or 22amp. I assume 22 since it is installed on a 1969 4500 that it would be 22amp?

Regulator looks like what is in the manual on the OUTSIDE, but it appears NO adjustments can be made on the coils/contacts. So, nothing in the manual helps at all on what or how to check anything..

Anything above low idle and the voltage keeps climbing right up to over 16 Volts. Shut it back down to idle quickly..

So, I need to know what amp hour the generator is and what regulator to purchase. Any suggestion on where to purchase would be helpful also.

Any other suggestions would be well appreciated. I'm so close to being able to run this thing again and then this happens!! Oh well, one more hurdle to climb.

In the meantime, I'll just disconnect the generator and run it without it until I resolve this charging issue. I did discover that if I unplugged the generator that the generator light on the dash stays on with the key OFF. Plug the gen back in and the light goes out.

My parts manual shows that for North America all '65-'75 4000 series tractors had 22 amp generators. The 11 amp version was apparently only used in Europe from '65 - '68, and the 22 amp model was used even in Europe after that... at least according to my parts book, but that doesn't necessarily mean that there might not be some with 11 amp generators out there.

got a diesel ford 59-64 b circuit reg laying around?

hot wire that up field to field, arm to arm, and bat over to battery hot.. see what you get for charge rate at battery with volt meter.

I think I found a regulator.. Will get that ordered tonight..

Appreciate the info. Just need to control the generator since it is definitely charging too high a voltage at over 16 volts!!

Thanks again.
