    Here is a post in the self help section.

    Voltage Regulators - Archive - Harley Davidson Community

    Regulator seems to be more used in battery charge and stator control.

    Check the coil? Look in self help section under electrical how to test coil. Plug wires are good?

    I think if you put a battery in it you would get spark to the plug but it won't recharge the battery.
