- Remove the fan belt (very important).
- Disconnect the arm and field wires from the generator.
- Using an alligator wire or spare jumper wire, connect arm to field on the generator.
- Then connect the negative side (ungrounded side) of the battery to this arm/field circuit.

Please let me know which step you are not sure on.

What we are doing is energizing the field circuit, which forms a magnetic field in the stator. At the same time we power the armature, which due to the magnetic field present, makes the generator spin like a motor.

Edit: field should be grounded not connected to power. Had it backwards.

Your car is positive ground, so the negative side of the battery is the "hot" side. The positive side is already connected to the generator via the case and chassis.
