    Run a separate ground wire right from the battery negative (assuming it's a neg. ground system) to the mount of the alternator. See if it helps.

    34-40 prior to removing the alternator the second time I used my heavy duty jumper cables and did exactly that. Shorted the negative terminal to the housing of the alternator directly. No change.
