Default Re: No Charge on Battery on F-1

The cut out relay inside the regulator is likely not pulling the points closed to start the charge process. The generator has to put out around 6 to 8-volts on residual magnetism alone to get the system up and running. This residual magnetism comes from the polarizing process but your generator should not have lost its polarity since it wasn't even on line during your testing. The cut out might be sticky. If this is a late model replacement regulator, I'd check that out first. Some of the new stuff is not very good quality.

If it now has a solid state regulator then there isn't much you can do. It depends on what components you have there. 12-volt conversions are all different now days. Some have the 3-pole old style regulators and some have all sorts of other types.
