5.5 TESTING
5.5.1 Test prior to starting engine
Before starting the engine, follow all steps in order of succession as described below:
1 Check whether all indication lights on the Alpha Pro charge regulator are off.
2 Energize the [reg on] terminal by either turning on the ignition switch (DO NOT START THE ENGINE) or by
putting a jumper across switch S1 (see Figure 17). Check whether the 3 yellow LEDs start to blink. After
approximately 10 seconds, the yellow bulk led will illuminate.

3 Check whether the alternator field is energized by touching the shaft of the alternator with a screwdriver. It
should be strongly magnetic.
4 De-energize the [reg on] terminal by turning off the ignition switch or by removing the jumper across switch S1
again. All LEDs should go off and the field should no longer be strongly magnetic.
If you cannot pass the tests mentioned above, remove the DC-fuses and double check the wiring. Refer to the
Trouble shooting section (section 8).
