TESTING
To check alternator output, connect an ammeter between
the red terminal on the rectifier and the ignition switch.
With the engine running at ISOOrpm, the ammeter should
indicate about 8 amperes into a fully discharged battery,
and progressively less as the battery becomes charged.
The regulator switches from high to low charge at about
14-1/2 volts and low to high at about 13 volts. Current
at low charge should be about 2amperes. If output is
unsatisfactory, do the following tests:
Rotor: To test for magnetism in the rotor, merely hold a
piece of steel close to the magnet. If the steel is
strongly attracted, the rotor is satisfactory. Strength
of the magnet is a basic quality that will not change
much over a period of time.
