    Advise, please. '93 Jeep Wrangler 4-banger. I set it up last fall with a very old Meyers ElectroLift & 6-foot blade. No power angle. It works great except that the lift really draws down the voltmeter and lights, etc. The longer I use it, the lower and dimmer things get. I'm just plowing 4 residential driveways around 300' each with small lots. So I may be plowing an hour and a half.
    The Wrangler seems to be equipped with a standard 90 amp alternator. Some have told me that I need to upgrade that. However, I talked to a fellow that rebuilds starters, alternators, etc., for a living, and he said 90 amp is about right and "don't waste your money".
    I do not know how many amps the ElectroLift draws. I'll run a test on it and see. What experiences have you guys had?

    I plow a few driveways with a 1992 Wrangler and Sno-way plow (I originally had a Western). I don’t know if any alternator can keep up with a plow motor (good thing it is only on for a few seconds). After a summer of not using the Jeep the alt was frozen the first couple years I plowed (I cant believe it still works), lately I have been spraying it down with WD-40 before it sits, which seems to keep it free. I did get the biggest battery I could fit in the tray.

    Yes - I was looking at the alternators at Alterstart. That exact one, but then my "expert" said, 'don't waste your money'. He DID ask if I had a deep cycle battery. Whatever that is.
