I found the chart I was talking about earlier. If you review the chart you will find that the output current of the 10SI, by design, is 0 below 1200 alternator shaft RPM. So what this says is that unless you are running the correct overdrive on the belts to get 1200+ alternator RPM at 500 engine RPM, then you will not have any charging. Most tractors I have run in the range of 1400-1600 engine RPM range. So unless I am at full throttle, I am not getting much output.

Some of the conversion kits I have seen have a special super small alternator pulley. Both of mine have the standard automotive pulley. Maybe that is my problem. I need to do like one of the other fellows said and make a 2" or smaller pulley. What are you and Hugh doing for the pulley?

Thanks!!
