1973 OPEL SERVICE MANUAL
6. Make sure all electrical accessories are turned
Start engine with battery post adapter switch closed;
open switch as soon as engine started.
7. Adjust engine speed to 2500 RPM.
8. Turn tester control knob to “LOAD” position
adjust knob to obtain highest possible ammeter r&d-
ing. Output must be 30 amperes minimum. If
is okay, proceed to voltage regulator test below.
9. If output is low, defect may
in alternator or
regulator. To eliminate regulator, supply
rent direct to cause full
output. Unplug
three-way connector from regulator and plug in a
jumper between the red and black leads. See Figure
Retest as described in Steps 7 and 8. If output
is still low, generator is faulty and must be
:

Alternator
Check
10. If output (using field jumper) is now okay, defect
is in the regulator or wiring harness. Check all wiring
connections. If all wiring is okay, try
regulator; if output now tests okay (without
field jumper), you have found the trouble. Always
follow-up with a voltage regulator test.
Test and Adjust Voltage Regulator Setting
1. Always test alternator output first, as
subparagraph a above. Leave all test
connected, but make sure field
is removed; if
used.
2. With engine speed at
RPM, turn tester con-
trol
knob
to
OHM” position. Make sure
electrical accessories are turned off. After
reading stabilizes, any reading between 13.5 and 14.5
volts is okay.
3. If voltage reading is out of limits, remove regulator
cover and adjust voltage regulator armature spring
tension to obtain a middle reading of 14.0 volts. If
reading fluctuates, voltage contacts are dirty.
4. Replace regulator cover and recheck voltage set-
ting. A steady voltage reading between 13.5 and 14.5
volts means voltage regulator is okay.
5. Adjust engine speed to specified idle. Reseal volt-
age regulator cover carefully, using electrical tape.
