Generator/Starter ~ Test, Rewind/Replace

[racton]

Hey gang... I have a 149 that has blown the old, and now a new, voltage regulator. I am assuming the generator is bad. A few questions:
How do I test my assumption?
What else might it be?
If it is the generator, should I replace it or rewind it?
Is there a good source for a replacement if that is the decision?
What is the air speed of an unladen swallow?

Cub Cadet FAQ #47 and #47a deals with testing and rebuilding starter/generator.
Or you can go to (Search forums) and look at previous posts about your subject.
If you search on this site you can learn just about anything you want to know about these tractors.

What is the air speed of an unladen swallow?

Depends on what you are swallowing.

Are you sure you had the new voltage regulator connected properly? Many have ruined a new regulator by improper wiring,
myself included.

African or European?

according to google ..unladen swallow ..20.1 mph...wonder what a loaded one does

 

[Reddoug]

If my memory serves me correctly, you can ground the field post on starter/gen and generator should put out full charge.
I don't have my old Cub Cadet to check.
Haven't worked with a generator for years.

Thanks for the comments and FAQ lead. If it's the generator is there a "performance" replacement I might consider?

 

[mgwin]

No need for a replacement. Just take it to a good alternator shop and have them rebuild it. Last time I checked, it would cost around $40.

 

[mgonitzke]

15 years ago a new set of field coils was about $60. No way are you getting it rebuilt for $40 today.

 

[gary noblit]

Matt, however, if it just needs brushes and cleanup plus bearings ,it's not too bad.Around $50. last I knew ..last new one I priced was $200...

 

[RAllison]

Can a guy rebuild one himself if he can find bearings brushes and field coils? Or is there something a shop does that can't be done at home?

Just had mine gone thru at an armature place here in Memphis like new 65$

 

[gary noblit]

I have done brushes and bearings but no equip to check coils..Often the armature needs to be refreshed on a lathe...I have a good guy locally so not considering doing it myself again. Most of the old ones need a serious cleanup inside as well...

isave tractors sells a rebuild kit: bearings, brushes,

I just got A starter generator redone at a place in Coopersville Michigan.

 

[dschwandt]

A rebuild shop may not look too kindly on one furnishing their own replacement parts.

Have you tried polarizing it?

 

[mgonitzke]

Have you tried polarizing it?

Not necessary on a starter/generator...that is done every time the tractor is started.

 

[James keil]

But if you disconnect battery.It has to be redone.
