#231322 voltage is dropping at the battery terminals when the car is on?
measure again cept this time ground the meter on the motor not the battery if you read improved voltage redo your grounds again. if your still reading a dropped voltage (Carefully!) check again with the terminals of your voltmeter directly on the alternator output (the big lonely one) and a good grounded spot on the motor, voltage should be slightly higher. if not your alt is bad
if voltage IS slightly higher swap the ground on the the motor for the neg battery terminal if your still reading improved voltage than either your 4gauge wire from your alt to your fuse box needs to be redone or the fuse for your alt has gone bad (70amp)
lemme know what happens :thumb:
