Re: IML: more on alternators

[aeyn <mr85000@xxxxxxxxx>]

Mikey,
     To clarify the point that I was trying to make with my 69
Imperial.  It had been changed to the old mechanical voltage
regulator and the old alternator, not the alternator made for the
transisterized voltage regulator.  So, in summary my 69 had the
same charging system as the rest of the 69 Chrysler line,
mechanical charging system.
