9n won't charge, did they ever?

Beyond frustrated with this. 43 9n. Looks to be good condition wiring harness. When I bought it it didn"t read a charge. New gauges, generator, put electronic voltage generator, and still nothing. Last week new India generator gave a glimmer of hope and with a amp gauge on the back I was getting 10-12 amps only shortly, then nothing. I sent that back when output screw came loose. Took my original generator and put a 6 amp 6v charger on it on the bench, and it spun slowly. I installed that on tractor and still no charge. Now I"m going to have to remove the hood and maybe look at the voltage reg (not a cutout) again. Maybe I"ll remove that and hook those two wires together to buypass it to see if it charges=is that a dumb idea? I"m at my wits end on this. Thanks

30 yrs. or so ago I converted my 8N to 12v. It starts every time since and battery will last forever it seems. All for about $100. Best money I ever spent.
 
"Last week new India generator"

Why? There is no shortage of original generators around. Just look at ebay.

" put electronic voltage generator"

I assume you mean an electronic regulator to replace the cut out. 2 to 3 time more expensive than a cut out and much more fragile.

" I"m going to have to remove the hood and maybe look at the voltage reg (not a cutout) again"

Why remove the hood?

"Maybe I"ll remove that and hook those two wires together to buypass it to see if it charges"

That sounds like a good ideas. Just don't leave them connected when you turn the tractor off.
 
I have 6 volt Fords that have been generating for over 60 years and work like new. I think Jmor will solve your problem.
 
if the genny motor tests ok.. run it without the cutout..but with an ammeter in line.. see what ya get.

Just quit fooling around with it and convert it to 12 volts.

*12V spins your engine much faster and starts it better in all conditions, especially if it is very cold or if the engine has marginal compression.
*12V with an alternator is more reliable and uses a solid state voltage regulator instead of an old fashioned system of points, coils and electromagnets to regulate the charging voltage.
Solid state is better, more accurate, more dependable.
*12V is more forgiving of dirty contacts on/in the entire wiring harness.
*12v is the industry standard and has been for 50 years.
*12v allows you to run sprayer pumps, flashing lights, winches and a host of other modern accessories on your tractor.
*12V lights are brighter.
*A 12v alternator will easily put out more amps than an old fashioned generator and vr.
*An alternator will charge at an idle. Generator generally will not.
*A 12v system is safer. For example, Most people know how to jump a 12v negative ground car, truck or tractor. Not many people know how to safely jump a 6v positive ground tractor with a 12 battery without something exploding in their faces or getting themselves run over.
*6v requires bigger, harder to find wires and cables throughout the system.
*12v batteries are to be found just about anywhere, are cheaper than 6v and are usually maintenance free.
*12v lets you use electronic ignition easily.
* And last but not least, is this your only 6V machine?
What kind of battery is in your boat, motorcycle, your RV, your classic car or even your 4 wheeler or snowmobile if you have them? Why have an odd ball battery that can't jump or be jumped by anything else?
 
I'll bet you have bad regulators. I went through four to get one that would last. Six months later it gave up. So did I. Mine is now 12 volt and it was less to do it than another new regulator.
 
Today I removed the two wires from electronic voltage regulator since the amp gauges still were not showing a charge (one gauge at rear of generator and one gauge in console). For an instant I started tractor and touched the two wires together that were on each side of regulator. I immediately showed 30 amps right after starting the tractor. I turned screw on generator to see if I could reduce the 30 amps but it didn"t, but just would then go to zero if I went to far. What do we conclude guys based upon this info? I do have a new tiawain voltage cutout I could install next. Thanks, Kurt
 
I removed the electronic regulator and put the new cutout on. Before starting the tractor, I polarized the cutout between it"s terminal. Seemed like I heard a click and there was a little spark. Started up the tractor and amp gauges read zero. I am letting it run for a while to see if the voltage increases on the battery. Currently it"s at 6.2 volts. I"m at a loss at this point on getting the gauge to read a charge. Kurt
 
When you put on the new cutout are you sure you got the wires
on the correct posts? May sound silly, but they only work one way.
 
Hi, yes, according to what was stamped batt on top, gen on bottom. When tractor runs I have batt voltage at batt terminal of cutout. When I check for voltage at generator I get nothing. When I bypass cutout I get 30 amps. I"ve been told the originl genny shouldn"t put out that much. With an electronic voltage reg or original cutout reg. I can not get to show charge. Only bypassing either reg. type the gauge shows a charge.
 
Could be a bad cutout, I've been hearing of quite a few lately.
I wouldn't run out and get one just yet since the regulator did the same.
Does your meter show discharge when you turn the lights on,
engine not running?
I just want to make sure when you jump that cutout it is actually
charging instead of discharging 30 amps.
 
I would check to or make sure you have the original cutout relay installed right. It will only work installed the correct way. If you are getting 30 amps bypassing the cut out and nothing with it either the cut out is wired wrong or is not working. Is the generator the correct type to be used with just a cutout relay?
 
Yes, the generator appears original to the tractor, with one wire coming off, and an adjusting screw for more current. Thanks
 
Well will need to give up on it for now. We"re in the mowing season and I"ll have to just keep charging the battery. In the past month it all hasn"t gone bad, I"ve replaced points, plugs, cap, rotor, condensor, spark plug wires, amp gauge, new steering wheel, cleaned air cleaner, changed hydraulic oil,rewired and installed new light switch and lights work & have ordered 1-3/8 pto conversion not here yet, removed 8v battery and put new 6volt in. Starts and runs great, just no charge. Thanks to anyone that has tried to help me.
