Polarizing generators and regulators
The following information and instructions are for your use, so your warranty will by in effect. No warranty can be in effect if these instructions are not followed. Whenever any component of a generator charged electrical system is serviced it is necessary to re-polarize the complete system, making sure it has the correct polarity so the system will charge in the right direction. If the system is put into service with the wrong polarity it may result in burned relay points, a dead battery and damage to both the regulator and generator.
1. To polarize a generator system with a mechanical regulator, momentarily connect a jumper wire of adequate gauge (a battery cable is ideal) between the “bat” and the “gen” terminal on the regulator after all wires have been properly connected and before starting the motor.
2. To polarize a generator system with electronic regulator/ rectifier. Before mounting the generator of the vehicle, place the generator on a non conducting work surface (like a wooden bench) and connect the positive terminal of a battery to the armature terminal of the generator. Then momentarily “flash” the negative battery terminal to the generator field terminal.
