440roadrunner said: I doubt that he's got a variable supply or he probably would not be asking, but I'm not convinced that your method will work????? A cutout has a series and a shunt winding. The shunt winding is the "voltage" winding, seems to me you'd have to connect the power supply to the A (G) and ground of the regulator, but it would be MORE accurate to watch for the voltage regulator relay to click in, no?

The regulator would have to be grounded for this test to work. I have never tried testing this way, but suspect that a 6/12-volt battery maintainer is all the variable power supply required. With the maintainer set at 6, a 6-volt cut-out should kick in and a 12-volt not.

I also think the test can probably be done without a battery, just connect a voltmeter between the regulator ground and BAT terminal.
