SpriteSpot Video Tech Tips

Polarizing the Generator & Troubleshooting the Charging System

This video a lot more than polarizing your generator--it's a how-to on troubleshooting the charging system (Generator and Control Box (Voltage Regulator). John demonstrates on an MG TD (but the principles apply to Spridgets as well). An excellent review of how the charging system works.

Polarizing your generator (by shorting terminals A & F on the control box) is important when changing from positive to negative ground.

John also describes how to trouble shoot using a 12 volt test light between the hot and terminal D to act as an ignition warning light, and how to use the wire from the F and the large wire from the D terminal to test your generator.
