    Did the high amp alternator require a new voltage regulator wiring harness or anything, or was it plug and play?

    Plug-n-Play. Internal regulator.

    I'd suggest a big 3 upgrade.... to anyone.

    I did the "big three" up when I moved the battery to the trunk and was shocked how much a difference it made. I even replaced the wire from the starter to the battery with 4ga and it actually cranks faster.
    2004 Silver Birch w/moonroof. "Isabelle"


    Eaton swapped summer/fall 2015 with all the gooddies, tune by the one-and-only Marty-O +2psi pulley, Steigemeyer stage 6 port, SWLT, custom ss exhaust, Borla ProXS, Addco sway bars, TCE s/s brake hoses, Hawk HPS pads, Zack big brak kit, J-mod, battery in trunk, full custom audio (never used, blower whine sounds better)

    To do list:
    HID headlights, LED interior/exterior, courtesy "3-flash" turn signals, widen wheels, rear deck wing, marauder stencil on cmhsl? bumper cover inserts? deck lid, steering whee, hood liner godshead, more power!

    Thanks Jim. I'm no electrologist, but if it wasn't an internal regulator then wouldn't it be a moot point about the regulator harness when changing the alternator?

    My issue is actually more intermittent than crocuses. After years of sitting I've had the MM out idling in this ridiculous heat for hours on end and I think the AC draw is just too much for an old alternator. I know the stock volt meter is unreliable but when it drops to 10.5 or 11V I tend to get cautious. The box store test said charging system tested ok, but my voltmeter disagrees.

    I don't follow about the regulator harness. The regulator is internal ie. inside the alternator.

    Your alternator should be putting out around 14volth even at idle. The stock voltmeter is a as reliable as an aftermarket one or a good meter.

    You could have bad connections at any of the grounds and positive points. One thing to check is the condition of the cables. sometimes there is corrosion inside the cables where you can't see it. Cables can be tested with an Ohm meter.
