COMMISSIONING
16 June 2007 / Alpha alternator - Alpha Pro regulator / EN
5 COMMISSIONING
CAUTION!
Check all wiring before commissioning:
positive connected to positive (red
cables), negative connected to negative
(black cables)
Commissioning of the Alpha alternator and the Alpha
Pro regulator involves two major parts:
• Testing
• Adjustments
5.1 TESTING
5.1.1 Test prior to starting engine
Before starting the engine follow all steps in order of
succession as described below:
1 Place the DC-fuse(s) to connect the batteries to
the wiring of the Alpha alternator and the Alpha
Pro regulator.
2 Check whether all indication lights on the Alpha
pro regulator are off.
3 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 13) Check whether the 3 green
LED’s start to blink. After approx. 10 seconds
the green bulk led will illuminate.

4 Check whether the alternator field is energized
by touching the shaft of the alternator with a
screwdriver. It should be strongly magnetic.
5 De-energize the [reg on] terminal by turning off
the ignition switch or by removing the jumper
across switch S1 again. All LED’s should go off
and the field should no longer be strongly
magnetic.
CAUTION!
After performing this test, be sure to turn
de-energize the [reg on] terminal,
otherwise the field windings of the
alternator will be damaged due to
overheating
If you cannot pass the above mentioned tests,
remove the DC-fuses and double check the wiring.
Refer to the Trouble shooting section (section 7).
6 Check whether all bolts are securely mounted
Check both the aligning and tension of the V-
belts.
5.1.2 In operation test
To check for proper operation you will need a hand
held digital meter. If you have installed a battery
monitor, such as a the Masterlink BTM or any other
digital voltage measuring device, you can use this as
well.
WARNING
When the engine is running, be aware of
moving parts like V-belts.
NOTE!
See section 3.2.1 for explanation of the
bulk, absorption and float mode.
• Be sure no loads or any other charging sources
are on!
• Be sure the battery is (almost) fully charged
