9N Generator Output

[deepspacedave]

My generator went out on my 9N, picked up an aftermarket one that's a direct replacement (6v system). Been reading that the output of the gen should be about 7.4, yet when I hook up my meter it reads twice that! I tested with it in place and running but no wires hooked up, I don't want to fry anything. So my question, if I hook it up at that voltage, is it going to fry something?

o it won't damage anything. A no-load test is not the correct procedure to test a generator. Measure battery terminal voltage after running & properly connected for about 3-5 minutes, at speed.

Thank you much!

I guess that if'N I was at a parts counter, I could be mistaken. I would ask "is your tractor set-up for 6 OR 12 volts?

If YOU are showing me a 12 VOLT generator, I would probably send you home with the same part.

The more RPM the generator is running, the more juice it will put out. Some sort of regulator will be needed to keep the generator from putting out too much juice.

QUESTION Is the tractor set-up for 12 Volts,???? Some of the older tractors have been converted from 6 volts systems to 12 volt systems.

It's a 6v system. It was actually this exact one that I installed --> http://www.amazon.com/DB-Electrical-GFD0002-Tractor-Generator/dp/B00Q8LRV98/ref=sr_1_1?ie=UTF8&qid=1446328044&sr=8-1&keywords=9n+generator

I can't say I'd recommend it. Had I not spent 2 hours getting the thing on I'd probably return it. Not well built at first glance!

Maybe the next time, try NAPA. I do not know how to purchase using internet sources.

I like to purchase local so I can take our community bus and leave the equipment in the garage.

First, the original 9N-10000-A and B generators output was about 7.5 amps -that's it. You most likely have a later 9N-10000-C or even a 2N-10000 generator at an 11.5 amp output rating. The 'A' and 'B' generators have a small 3-1/2" or so barrel and pulley diameter. The 'A' genny is a 2-wire/2-brush 'B' Circuit type and uses a special square voltage regulator. The 'B' genny is the same size but now is a 1-wire/3-brush 'A' circuit type and uses the round-can cutout. Don't get confused with A & B generators and a & B circuits -two different animals -read my article on the 'other' web site, I sent you an email with the link. It wasn't until the 9N-10000-C generator was introduced that the output was changed to about 11.5 amps. The 2N-10000 was the same too. I suspect you have one or the other.

As Jmor said. you measured an unloaded armature voltage.. a fairly useless test.

hook up, run, measure, post back.
