Hello…I will be installing a 3 brush generator on my 37 engine. The generator has 2 wires coming out of the top of the generator body. What is the procedure for correctly installing the cutout and for polarizing the generator for the standard positive ground system? Since I am a real electrical dummy, a simple instruction would be greatly appreciated! Thanks!

A three brush generator uses a cutout and a movable brush to regulate charging rate. A two brush generator requires a voltage regulator connected to the armature and field terminals. They are not directly interchangeable. Your three brush generator has one connection to ground, and the other to the input side of the cutout. Polarization is not necessary unless the generator output fails.

Sorry for my ingorance, but...Which wire coming from the distributor is connected to the ground and which one is connected to the input side of the cutout?? Is there an easy way to differentiate the 2 wires?

Usually, the wire to the cutout input is yellow, sometimes with a black tracer, while the ground wire is black. The cutout wire should emerge thru the grommet in the case next to the cutout. The purpose of the ground wire is to provide the ground for the field coils, while the output goes to the moveable brush. Don't worry about questions being ignorant.
