9 N charging issues

The stock generator is putting out 7.5
AMPS. I am only showing 6 volts at the
battery terminal of the cutout.

I have a aftermarket generator that shows
25 AMPS at the generator. I'm only showing
6 volts at the battery terminal

I have polarized the system with every
testing.

I have run a jumper wire from the out put
post of the generator to the battery
terminal on the cutout. Nothing changes.

Jumper wire straight to the battery,
nothing changes.

I'm beginning to believe this tractor is
possessed.

All test are at and idle, and at 2/3
throttle.

I have read everything I can find on this
topic including the owners manual, the
archives here.

Thank You for your time.

ou say that the generators are outputing 7.5AMPS and 25AMPS....how are you measuring that? I am very skeptical.
 
I did rebuild the generator on my 8N51 due to a squeaking generator bearing. While doing this I performed all electrical tests as described in the shop manual. The process was pretty clear and voltage and amp readings were spot on as described in the manual. I realize the 9N is a little different but I strongly suggest following the testing procedure in the manual.

I'm not saying the meter is accurate,. I'm just telling you what the meter is saying, What makes you concerned about the accuracy of my meter? Apparently you can't help with the question! Just on of those guys that has to respond to any and all post, thanks for your infinite wisdom!
 
I understand you being skeptical, So am
I, I am reading it at the generator in
AMPS, With the out put wire hooked up and
without it being hooked up,. Thank You for
your time,
 
Thank You for your response,. I will look
at the manual more closely, Thanks again
for your response,

MPS is current flow and in order to have amps the current has to be flowing to some place. Amps is measured with the meter in SERIES with the wire carrying current. You are probably setting the meter to AMPS and connecting the leads wrong and thinking you are measuring generator output amps when in fact you are not.....my best assessment from far away.
 
trimmer you are going to have to get thicker skin if you want to be on this forum , all responses are not trying to slam your face in the mud
 
Thanks everyone for the suggestions, Duey I need to apologize for the harsh words. I know you were just trying to help.

Thanks again for your time,
 
Does your generator have a belt tensioner device on it? What does your AMMETER show when running? If no proper belt tension is used, unit will never get charged. So you have two generators, one OEM original and one aftermarket unit? Only the first two 9N generators were 7.5A output. But neither had a belt tensioner device. The 9N-A and 9N-B units had the small diameter 3-1/2" barrels. The first was the 9N-10000-A, a 2-Wire/2-Brush, 'B' Circuit unit with a rectangular Voltage Regulator. Rare. The second was the 9N-10000-B unit, (also rare)a 1-Wire/3-Brush 'A' Circuit unit with the roundcan cutout. The 9N-B unit had a 3rd Brush Hi-Lo adjustment slider button the back panel. A Generator and Cutout tells us it is 6V and used on all 9N & 2N tractors after s/n 12500. How is the rest of the wiring? The 9N-10000-C unit was next with an 11 AMP output and larger barrel and armature. All new aftermarket generators made and sold today for the 9N/2N are like this: 1-Wire/3-Brush units that should have a screw terminal 3rd Brush adjustment. No telling how aftermarket units are cloned; there are quite a few Cheena made suppliers and could possibly be 20A units. Ford didn't releases a 20 AMP generator until the mid-8N model. "...I have polarized the system with every testing..." How was tis done? Power "ON" or "OFF"? Polarizing generator can be done by arc-sparking the cutout BAT to ARM terminals no power applied. Forget polarizing until you can verify all the wiring is correct and are ready to fire up. Get your ESSENTIAL MANUALS and verify with your VOM set to continuity the entire wiring system. Don't use test light. Disconnect battery and any lighting system you have. Lights were not OEM from the Rouge factory and often get wired incorrectly. Once your root cause problem is solved, you can wire lights back up. Again, gen belt tension is mandatory.

Just don't ask about the torque values of any bolts,you'll get roasted. After 45 years on commercial construction jobs,I have pretty thick skin,so it was simply an unwanted irritation,kinda like poison ivy.
