Gerator on Super A causing me Grief.

Posted by Brian on October 22, 2003 at 19:51:13 from (65.48.189.192):

I posted a couple of weeks ago that I was have problems with charging on my super A. It is a 6volt system, has the 4 position switch and a mag ignition. Here's what I've done.

1. Had the generator checked out by a local shop, they said that although dirty the generator itself was fine. They gave it a cleaning and it looks good. They did say that the voltage regulator may have been bad and put a new one on. We made sure it was set up for positive ground and it was re-polarized.

2. I checked the wiring to BOB M's diagrams...unless there is something I'm missing it looks good.

3. I checked the continuity in the wires to make sure they were ok and they seem fine.

4. There is 7 volts between the bat terminal on the regulator and ground (bat. volt obviously). My understanding is that there should be more like 10volts when the tractor is running.

5. I have the belt hooked up.

6. I'm pretty sure the gauge works, it worked at the begining of the year showing charge, and when I turn on the lights it show neg. current of about 10 amps. When I run the tractor though it doesn't move to the positve.

7. I've tried the switch in both positions, low and high.

8. I've checked for continuity between the batt terminal on the starter and the gauge, between the gauge and the fuse and the fuse to the switch. I've also check between the amp gauge and the batt terminal on the regulator. I've also got a good wire between the field and the screw which attaches to the resistor that comes on the switch.

9. There is continuity between the screw before the resistor and after, although there didn't seem to be much resistence with the switch in either position.

I just can't seem to get this thing to show a charge. Anyone have any suggestions befor I go bald from pulling my hair out ? I'm in the dark here.

Thanks for you replies.

Brian.
