ALTERNATOR PRECAUTIONS



To prevent damage to the alternator and regulator, the following precautionary measures must be taken when working with the electrical system.

  1. Never reverse battery connections.
  2.  
  3. Booster batteries for starting must be connected properly. Make sure that the positive cable of the booster battery is connected to the positive terminal of the battery that is getting the boost and negative cable to ground.
  4.  
  5. Disconnect the battery cables before using a fast charger; the charger has a tendency to force current through the diodes in the opposite direction for which they are designed. This burns out the diodes.

  7. Never use a fast charger as a booster for starting the vehicle.

  14.
