Re: Alternators

[Bill Maurits <Y1TopBanana73@xxxxxxxxx>]

The VR I got is supposed to be an electronic replacement of the
original mechanical unit for my car. Looking straight at it from the
top, the new elec and old mech versions look identical, but from the
side, the new elec one is MUCH shorter.

I've checked all my grounds and connections, but haven't tested the
VR. I'll do that soon. I'm wondering if the car had a much higher amp
alt that someone swapped the single groove pulley on to, but I have to
find a local shop w/ a tester that does something besides say 'good'
or 'bad'.
