Suggest that you recheck the connection on the voltage regulator!
\015\012Next, start the engine and place a good voltmeter across the battery terminals and read the voltage at idle with nothing on.
\015\012Next, turn on the headlights and read the voltage. If it drops more than 2 tenths of a volt (goes from 14.2 to less than 14 volts) the regulator is bad. If the voltage is always less than 13.5 with the engine running - chances are that you got a bad generator!!
