Question about generator
 

I'm familiar with the NF Cubs having a starter/generator that was run by a belt off the front of the engine, and I'm also aware that with the introduction of the quietline series a direct starter was introduced (on the flywheel) however, I do not know what replaced the generator (from the NFrames.) I've done some research and nothing seems to be coming up. What produces the current on the quietline series?

Thanks!

They have an alternator like current engines.

Also known as a "stator". It is behind the flywheel. A pain to replace.

Thank you this helps clarify completely.

Yeah wierd to go from something as reliable as a S/G to a little stator that puts out around 28 volts AC and has to be rectified back to 12-14V. Oh well, they rarely go bad IME and the regulator/rectifier is easy to replace when it goes up...

Progress marches on. Sometimes backwards, I agree!

Actually,
Stator/rect system charges@ lower rpms, is less costly to produce, is lighter weight and no moving parts to wear out.
what's not to like about that?

How is that backwards? The stator/alternator is higher output, and in my experience has been far more reliable than starter/generators. You're forgetting the mechanical voltage regulator for the S/G system, which needs periodic adjustment.

I have spent more time troubleshooting ONE S/G charging system problem than I have spent troubleshooting the more modern alternator/rectifier systems on tractors I have owned that were equipped with them...

I'll agree to that. That is one nice thing I like about my 12, 14, and 1650. Never had to work on the charging system. S/G's are nice too, but you do spend quite a bit more time looking for solutions.

Thanks everyone for the replies; I know more than I ever did about them, and I'm not complaining.

I'm guessing that when alternators and rectifiers fail in say, 50 years, that there will not be a $14 rebuild kit available on Ebay to repair them, as there is on 50 year old Delco S/Gs./

Similarly new cars are more reliable until they fail. Then they're largely bricks that are unfixable by normal people with normal tools.

I'll accept periodic maintenance in trade for repair-ability, but everyone has a preference. (This is a vintage tractor forum ...no?)

The end user cannot repair the individual components of either system... if the voltage regulator (or rectifier) dies, you replace it. If the field coils or armature (or stator) dies, you replace it. On top of that, with the S/G you have to deal with brushes, bearings, and a belt.

Not sure why you think that the S/G system is easier or better when there are more components that can fail and none of them can be repaired either...
