Voltage lower than 9.6 Volt
Voltage above 9.6 Volt
No waving
1. If the starting voltage is normal, press
2. Run the engine between 1200 and 1500 rpm.
3. One of the 3 results is displayed:
Result of the start voltage test
Examples
High starting voltage when the test is
performed with the engine at idle
Normal starting voltage when the test
is performed with the engine at idle
Low starting voltage when the test is
performed with the engine at idle
• Result of the load system test with consumables running
1. Turn on the heater to maximum (heat), headlights and taillights. Do not switch on cyclic loads such as air conditioning or
windshield wipers.
Examples
High starting voltage whenthe test is
performed with the consumers running
"Normal starting voltage
when the test is performed with the
consumers running"
"Low starting voltage when
the test is performed with the consu-
mers running"
2. Press to display the ripple intensity of the charging circuit. The display shows « RIPPLE & XX.XX V ».

The starting voltage is not correct. The battery must be
LO
replaced.
OK The starting voltage is normal.
"The starting voltage is not detected. Check the connec-
---- tions, cables and alternator.
Repeat the test."

Check that the connections are good. If every-
HI (= High)
thing is properly connected, replace the alterna-
tor.
No problem detected. Normal operation of the
OK
alternator.
The alternator does not provide enough power to
the battery. Check the alternator belts, and make
sure the alternator is running when the engine is
running. If the belts slip or are broken, replace
LO (= LOW)
them and re-test. Check the connection between
the alternator and the battery. If the connection
is bad, clean or replace the cable and re-test. If
the alternator belts and connection are in good
condition, replace the alternator.

"The output voltage of the alternator is abnormally
high. Check that there are no connection problems.
HI (= High)
If not, replace
the alternator."
No problem detected. Normal operation of the
OK
alternator.
The alternator does not provide enough current
for charging the electrical system and the battery.
Check the alternator belts, and make sure the alter-
nator is running when the engine is running. If the
timing belts slip or are broken, replace the timing
LO (= LOW)
belts and re-test. Check the connection between the
alternator and the battery. If the connection is bad,
clean or replace the cable and re-test. If the belts
and connection are in good condition, replace the
alternator.

The diodes work well in the alternator/starter
"One or more diodes do not
do not work or are
damaged. Make sure that the alternator
support is properly positioned and that the
belts are working properly. If so, replace the
alternator."
