Charging Problems

Postby CubScout » Fri Apr 09, 2004 10:51 am

This is what I have figured out so far.
The ammeter does not move when on/off swich is used.
The generator tested ok.
I cleaned the contacts on the cut-out.
Ammeter shows discharge when points on cutout are contacted.
The cut-out has been polarized.
Tried grounding F terminal of cut-out to ground.
Have gone over the wiring numerous times to be sure its wired right.
All wiring is new and ammeter is new.

I have looked through the generator/cutout flow chart and know I have problems. I can't figure out why my ammeter is not showing anything when I pull out the switch. It does move a bit to the discharge side when cranking the engine over. Anyways I'm beginning to think it might be my charge/headlight selector switch. Is that a possibility?

Thanks,
Kevin

Make sure you have a good ground where the dash attaches to the torque tube.

Do you have battery ignition? If you have a magneto, turning the ignition on will not show anything at the ammeter.

Also, it won't show any discharge on a battey ignition if the points in the distributor happen to be in the open position. You said you polarized the cutout, but the genreator is what needs to be polarized.

Get a cheap digital voltmeter form Walmart, Autozone, etc. and do some checking. With the engine running, you should get a minimum 6.5 up to 7.8 at the generator output, and also on both sides of the cutout, and battery. If you have the 6.5 or higher on the generator side of the cutout, but a lower voltage on the battery side, the cutout is not working.
If you are not part of the solution,
you are part of the problem!!!

I thought to polarize you had to jump a wire from the gen and bat terminals of the cutout???? I do have battery ignition. Before I can check all these things I have to rig up some sort of gas tank so I can run the tractor with the hood off. Maybe that will be tomorrow mornings project.

Thanks

I'll make one modification to John's comments. I suggest a cheap analog multimeter rather than a digital one. A digital meter tends to jump around because output from the generator can be pertty dirty. An analog meter damps that out and just gives you the average.

Cub scout, You are correct on the location of the terminals. But, what that does, in actuality, is apply battery voltage to the armature terminal of the generator setting up a residual magnetic field. The terminals at the regulator or cut-out are used because the 2 points involved in the process are close together. The gen. terminal goes to the generator armature terminal and the batt terminal goes to the battery hot terminal. It's just a convenient spot to perform the job.
