Hi Volks,
    It is a good practice to check the battery voltage when changing the
alternator / voltage regulator. Have your meter connected between plus and
minus battery when you first bring up a replacement. Should be around 14
volts, if you have over 15 volts there is a problem. Observe the voltage for
a bit while the alternator is doing its' thing. Excessive voltage can take
out your ecu and other electronic goodies that happen to be operating.
