    Talking Checking out a generator

    Does anyone know how to check out a used generator for a 1962 Evinrude 40 h.p. motor that it charges? I have a motor w/o the generator, but have found one off another motor, but have no history of it. The generator is a RK-24L.

    You can run it like a starter motor just ground out the field terminal and apply pos to the armature the motor should spin. Just to be clear run a jumper wire from ground to the field terminal ground the chassis and touch battery pos to the arm post.

    Hook up a volt meter to the two posts of the generator.
    Also run a jumper wire from the "Field" post to a ground anywhere on the generator
    Hold the pulley against a wire wheel of a bench grinder so that the pulley turns in the proper direction.
    Observe the volt meter... it should peg the meter at 12v or more.
    We occasionally have questions. If you fail to answer, it may affect ours.

    I`m not sure if that test will work if the generator is not polarized first? By using a battery that will polarize the generator at the same time.

    Kim.... Something I've done many times, yeah it works as long as the field is grounded.

    Is this generator considered an "A" type or "B" type circuit generator ??

    The field coils circuit. "A" field is externally grounded by the regulator. "B" field is internally grounded and takes a different kind of regulator.
