I had this same problem several years ago and came up with a rather simple test.I had a variable dc voltage (0 to 30 volts dc at 1.25 amperes) power supply that I purchased from Radio Shack a few years ago.By connecting the power supply accross the winding for the cut out and connecting a voltmeter in parallel to the power supply, I found that I could increase and decrease the output voltage of the power supply and note the exact pick up and drop out voltage of the cut out.This action simulated the increase and decrease of the voltage output of the generator.The pick up point does not need to be the same as the drop out point.Pick up can be about 7 1/2 to 8 volts with drop out above a 6 volt overcharge rate or about 7 volts.Ford published these exact voltages, but I do not have them handy now. I hope that this helps.If you want more info on this test, just let me know.

: With the cut-out off of the generator, and apart, is there a simple bench test that can be made to assess if the contact points are closing at the appropriate moment?Or, does one require a sophisticated load-bearing device in order to place unequal loads on both terminals?
: I was hoping that I could place a battery charger on one side of the cut-out to effect a closing of the points.
: Thanks much.
