[DeTomaso] Alternator question

[Dave Londry]

6143 has a Gilmer drive that services waterpump, alternator and AC.
Chuck & I were speculating on the need for a Gilmer in a street car and 
we underestimated the alternator load.
Re-thinking that; you're right, 150 amps is a V-belt problem,
  even if that's only during the battery recharge cycle after a start.
