Because alternator design is unique, special care must be taken when servicing the charging system.

  1. Battery polarity should be checked before any connections, such as jumper cables or battery charger leads, are made. Reversed battery connections will damage the diode rectifiers. It is recommended that the battery cables be disconnected before connecting a battery charger.
  2.  
  3. The battery must never be disconnected while the alternator is running because the regulator will be destroyed.
  4.  
  5. Always disconnect the battery ground lead before replacing the alternator.
  6.  
  7. Do not attempt to polarize an alternator.
  8.  
  9. Do not short across or ground any alternator terminals.
  10.  
  11. Always disconnect the battery ground lead before removing the alternator output cable, whether the engine is running or not.
  12.  
  13. If electric arc welding has to be done on the car, first disconnect the battery and alternator cables. Never start the car with the welding unit attached.
  14.  

REMOVAL & INSTALLATION



  1. Disconnect the battery ground cable to prevent diode damage.
  2.  
  3. Disconnect the Delcotron wiring.
  4.  
  5. Remove the generator brace bolt. If the car is equipped with power steering, loosen the pump brace and mount nuts. Detach the drive belt(s).
  6.  
  7. Support the generator and remove the mount bolt(s). Remove the unit from the vehicle.
  8.
