1944 2N charging system

[Dave H (MI)]

I hate this. There isn't much to this and you would think I could get thru it without any trouble but....

I gots pretty much all new on this system. The genny is the original. The wires is all new. I just installed a new cut-out and a new ammeter. Carefully checked the wires to make sure I hooked up the BATT terminal from the cut-out to the ammeter post. Put a jumper from the other post to the resistor block center post. Polarized the genny by touching the BATT terminal of the cut-out to the one and only post on the genny.

I got NO reading on the new ammeter. I expect this sort of thing when I try to keep the original equipment on the tractor but not when it is mostly new. Not an electrical system expert so I could use some suggestions on testing the system components to track down the problem.

Dave,Did you get a spark when you polarized the genny by touching the BATT terminal of the cut-out to the one and only post on the genny.It should have sparked when you touched the wire to the post.You could test the generator by taking the belt off and jumper it the same way that you did when you polarized it seeing if it motors.If it motors ,it should charge.If it won't motor it won't charge and the generator needs repaired.

Yessir...got a spark when I did the polarization. It would help if I knew a little more about the generator. Are you saying that if I apply voltage to the one post on the genny it should turn? That's what I am reading. Is there another way, say with a voltmeter to check output? I think I can check the ammeter just by applying voltage thru it. The cut-out and generator are a little more puzzling. Still reading the FO-4 to see if it gives me any diagnostics that would be helpful.

See if this helps.

Dave........pay attention 'cuz it gitts tricky here.
To POLARIZE the 2-terminal roundcan cut-out underneath yer battery tray, simply "arc-spark" the 2-terminals together, engine OFF. I use a pair of pliers handles, you can use barb'd-warr or bailin'wire iff'n you want.

You can "re-polarize" as many times as it takes to feel warm and fuzzy ...er... charging. Simple, eh? ......Dell,the charged

I sent you an e-mail. IF there is any way you can send me a copy of that document back it would be very much appreciated!

check your email!

Doh! I was thinkin you said to arc across the terminals on the GENNY and scratched my head for a while trying to figure out why there was only one. Guess I shoulda paid closer attention cause it was confusing! I just did what the book told me to do which was basically the same...just not so easy. I kept waiting for it to give me a poke.

the cut-out is either on or off it's main job is to open the points when you turn off the motor so that the generator does'nt motor,running down your battery---lha
