8. Magnetizing the rotor.
the rotor to provide sufficient voltage build-up to turn on the field
circuit when the engine is started. However, units that have been in
inventory, disassembled or serviced may need to have this magnetism
re-established. This is accomplished by magnetizing the rotor. To
magnetize the rotor, connect the alternator to the electrical system in
the normal manner. With the engine off momentarily,
connect a jumper lead from the battery positive to the
relay terminal of the alternator. (The relay terminal is the
small pin type terminal generally covered by a rubber cap.) This
applies to both positive and negative ground systems. This will
restore the magnetism in the rotor and the alternator will begin
operating correctly.
9. Test alternator operation.
be 20% over total system requirements. The regulator has
been preset to O.E. specifications. Vehicle indicator gauges may not
reveal accurate charging system operation. Reliable test equipment
should be used when testing or troubleshooting the electrical system.
