    Polarizing jenny

    just found this from a very old posting "I assume it is a charging problem, and since you didn't specify 9/2N or 8N (the 8 uses a 3 lead generator with voltage regulator), I will assume the single lead 6 volt, which is the one that was a bugger for me. Place the ground lead of the multi...

    well we will see where it goes tomorrow....but I just discovered a few minutes ago....the heavens are looking down on me... there is an antique tractor show tomorrow!! right next door. What fun... and thanks for the help. I'm sure the folks at the show after my thousand questions will run...

    OK , I've ordered my FO-4 manual but it will be days before it comes. I can't find anywhere how to motor test a single terminal generator. It appears to be a three brush generator. As shown, one wire attached.

    Other end goes to starter switch. I'm searching how to do the motor test on the single terminal generator. Looks like apply voltage to the single terminal and ground the case. Just conforming before I blow the generator. I do see half a volt when it's running between the single generator...

    double confirming but its + to the center tap of the resistor. tractor is positive ground. it runs quite well, just doesn't charge. Voltage on battery shows no change at any rpm. ammeter shows nothing running or not. if i jumper the round top cut out ammeter shows negative amps being...

    good catch. It's a starting switch. Not a solenoid. Taking a picture of that now with the round cap. one additional observation. The ammeter has - & + labels but none of the diagrams show if that matters what is hooked up to what. I'm thinking it does. I'm a mechanical guy sorry.

    i did miss it. I'm using the ammeter on the tractor, analog. I've reviewed the wiring diagrams looks all correct to me. ammeter negative pole goes to solenoid. + pole goes to center stud on resistor.

    6 volt, correct. + side of ammeter hooked to center tap of resistor engine speed has no effect on battery voltage or ammeter. if i jumper the cutout , engine off i see a 20 amp draw, key on or off. if I turn on the engine and jumper the cutout i see a 10 amp draw jumper means for me short...

    battery is 6.3 volts. jumper the cutout, the ammeter shows negative 10 amps.

    sounds good. Thanks for the replies. negative voltage on the ammeter. ? my issue is?

    Polarizing jenny

    ok... I'm back in the garage. 6.3 volts. Positive ground on the battery. Started her up no difference. 6.3 volts. No indication on the amp meter. shut her off. jumped between the neg battery terminal and the big wire on the jenny. small spark. started her up, no difference on the amp...

    The beauty of these forums is the ability to post photos, then regardless of the terms you use we know what you are talking about. You should have a round can type cutout relay, but there is also a cutout relay in the voltage regulator found on later machines. They both serve the same...

    It may not be necessary. I believe I am confused by other posts on this subject where folks are talking about bending the points, filing them , etc , all in reference to the cut out I thought. I know I can electrically test it by apply voltage on the jenny side where it should close and and...

    Polarizing jenny

    so how does one remove the round top cap from the cut out ?

    Polarizing jenny

    My apologies... I'm just a simple weekend tinker that when typing early morning makes spelling mistakes. round cap = round can cut out (I'm using descriptions referred to inside this forum and they may or may not be accurate and obviously said cap vs. can) and the contacts I was referring...

    Polarizing jenny

    ok, I believe I have it. I do have a positive ground battery. What had happened was the switch had been left on and the battery completely drained. It was the napa 6 volt. I went to try and recharge the battery , without disconnecting it I may say and thinking on that that was a no no , and...

    Polarizing jenny

    I have the round can cutout. i must be jus plan dumb.... when they say arc the two terminals it means connect the batt terminal and the one unlabeled on the cutout for a sec or two? I've read 10 other posts and its just not obvious to me. It's interesting with the stealth fun projects...
