Pulse Generator
- Remove pulse generator from vehicle. Apply 12 volts to terminal No. 1 (positive) and ground terminal No. 3 (negative). Also connect a 3000-10,000 ohm resistor in-line between terminal No. 2 and power supply to terminal No. 1. SeeFig 1 .
- Install a voltmeter between terminals No. 2 and No. 3. Rotate pulse generator and verify that one revolution equals 4 meter deflections.
