[Healeys] Alternator Pulleys

Wed Aug 14 11:45:32 MDT 2019

You know here is a difference between an old car and a classic car.

The classic car got points, a generator, lever shocks, a period gearbox, 
crossply tyres and no electric/electronic gadgets.

An old car allows all to drive it, a classic car only allows those to drive 
it propperly who are sensible enough to understand the classic car´s sole. 
So its easy to recognise the competent classic car enthusiast.

    You guys are just too critical.  My BJ8 (with Toyota 5-speed) is still
    a real Healey.  I can tell by the oil leaks. I think that the
    transmission drips a bit too just to keep the rest of the car happy.

    Real Healeys don't have alternators

      In any event, unless you are doing significantly more idling than
      driving this drawdown duning idling is not really significant. This
      is what the battery is for. If you had an ammeter you would see the
      amps pick up after idling to bring the batt back up to full volts.

      Of couse you need a good batt, and alternator.

      > Hi Price, alternators do not kick in until they are rotating at
      about 1200 alternator RPM. The pulley ratio is approximately 3:1 when
      comparing the bottom crank pulley to the alternator pulley. At idle
      of 800 RPM the alternator would be rotating at 2400 RPM so you should
      have a good output at idle. The smaller the alternator pulley the
      faster it will spin.

      > I have installed an alternator in my BJ8 to support ac with mixed
      success. Since our cars use a v-belt system I had to replace the
      pulley that came with the alternator(serpentine) with a v-belt
      pulley.  I have checked the power the alternator and at idle, it is
      below the amperage needed to run the equipment I have installed.

      serpentine pulley, the v-belt is definitely smaller. Should I use a
      v-belt pulley of similar size?  Increasing the circumference of the
      pulley will make the alternator spin faster and maybe solve my issue
      of slow engine speed/low amp output, I think.

      >

      > If my thinking is correct, how big of a pulley should I use?  I
      presume that if the pulley is too large, it may make the alternator
      produce too many amps and damage it.  Should I match the size of the
      serpentine pulley or buy a pulley based on a calculation?  (FWIW, I
      have no knowledge/experience to do this).

      >

      > The pulleys on the crank and water pump are standard Healey. There
      is ac installed and the pulley on the compressor is larger than the
      old generator. I have a two belt system so the alternator is belted
      to the compressor which if what I said above about larger pulleys
      spin their equipment faster, how should this be accounted for?

      resolution?
