[AT] [Farmall] Super M generator belt / tensioning bracket

Your voltage regulator might need a little adjustment. When properly 
set, you should be seeing 13.6 volts at the battery when the engine is 
running at "high idle". At idle, those old tractor would often not be 
able to keep up with the ignition system drain. That is one reason why a 
alternator is generally a better choice than a generator for a charging 
circuit. I am sure that others will have their own thoughts on this...
