BATTERY IS
DAMAGED
OR WEAK
1.
SA TTERY TEST
Remove
the
battery (page 17-6),
Check
the
battery cond
ition
using the recommended batte
ry
tester.
RECOMMENDED BATTERY TESTER:
Micro
404XL
(U
.S.A. only), BM·210
or
equivalent
Is
the
battBry in
good
condition?
NO
- Faulty battery.
YES

NO -
GO
TO STEP 3.
3. CURRENT LEAKAGE TEST
WITHOUT
REGULATOR/ RECTIFIER CONNECTED
Disconnect the regulator/rectifier
connector
and recheck
the
battery current leakage.
Is
the
current
leakage
below
O. 1 rnA?
YES
- Faulty regulator/rectifier.
NO
- Shorted wire ha
rn
ess.
4. ALTERNATOR CHARGING
COil
INSPECTION
Check
the
al
ternator charging coil !page
17
-8).
Check
for
contin
u
ity
between
Yellow
terminal
and Ground, White termi
nal
and
Gr
ound.
Is there
continuity
?
NO
- Faulty charging coil.
YES - GO TO S
TE

5. CHARGING VOLTAGE INSPECTION
Measure and record the
banery
voltage using a digital
mul
t
ime
ter !page 17-6).
Start the en
gi

e.
Measure
the
charging voltage (page 17-7).
Compare the measurements to the results
of
the
fo
ll
owing
calculation.
STANDARD:
Measured BV < Measured CV < 15.5 V
• BV =
Batt

6. REGULATOR/RECTIFIER SYSTEM INSPECTION
Check the voltage and resistance at the regulator/rectifier
connector
(page
