VEHICLE WIRING HARNESS TEST
1. Place positive (+) lead from voltmeter in the TACH calibration jack and the
negative (–) lead to frame. Set on 0-20vdc scale.
2. Start engine, advance engine to 1200 RPM and return to idle.
3. Increase and decrease engine RPM and observe voltmeter. The voltage
should increase and decrease with engine speed.
4. Place positive (+) lead from voltmeter in the engage jack. If there is no volt-
age then unit is not receiving current on the red wire.
