Well did a little checking and here is the latest, with the voltage regulator plugged in the cart will do as before. If I unplug the regulator the starter will only spin for a couple seconds and then stop (obviously the cart will not run). If plugged in I can drive the cart with no evidence of problems until I let off the gas pedal and the starter will spin as if still depressed (slowly). In past post some folks have said it could be voltage regulator but I have checked and everything else looks as it did prior to other parts changes.
