Generator Test (Overcharged Battery Check); Repair Instructions; Jump Starting In Case Of Emergency - Suzuki 2006 SX4 Service Manual

1J-6 Charging System:
3) Ground "F" terminal and start engine, then measure
voltage at "B" terminal as shown in figure.
• Voltage is higher than standard value. It is
considered that generator itself is good but IC
regulator has been damaged, replace IC
regulator.
• Voltage is lower than standard value. It is
considered that generator itself has problem,
check the generator.
Load Check
1) Run engine at 2,000 rpm and turn on head light and
heater motor.
2) Measure current and if it is less than 20 A, repair or
replace generator.

Jump Starting in Case of Emergency

With Auxiliary (Booster) Battery
CAUTION
!
If vehicle is manual transaxle model and has
a catalytic converter, do not push or tow it to
start. Damage to its emission system and/or
to other parts may result.
Both booster and discharged battery should be treated
carefully when using jumper cables. Follow the
procedure outlined as follows, being careful not to cause
sparks.

Generator Test (Overcharged Battery Check)

1) To determine battery condition, refer to "Battery
Description".
2) If obvious overcharged condition exists as evidenced
by excessive spewing of electrolyte, measure
generator "B" terminal voltage at engine 2000 rpm.
3) If measured voltage is higher than upper limit value,
disassemble generator.
4) Check ground of brushes. If brushes are not
grounded, replace IC regulator. Then check field coil
for grounds and shorts.
