If you cant return those regulators for refund or exchange, you may just need to adjust the field relay spring a bit tighter. Adjusting the old vibrating contact regulators is a bit of a learned skill, but can be done quite easily with only a voltmeter. The cutout relay has the heavy wire windings in it's coil. The field relay that you need to adjust has the very small wire windings. Disconnect a battery cable any time you install or remove a regulator cover, If you touch the cover to a Hot internal connection and the base, the regulator may be ruined by the short circuit. With the battery disconnected, your safe. Always install the regulator cover before checking the final voltage setting. The battery must be fully charged and the regulator at operating temperature, so run it for 15 minutes before the final tweeking. The steel cover changes the magnetic field in the regulator and can affect the voltage setting by 1/2 volt or more.

BTW, there are several outfits making replacement solid state regulators for older 6 and 12V generator systems. Do a google search for "solid state generator regulator"
