BATTERY INSPECTION

MZR-CD (RF Turbo)
Battery
1. Inspect the battery with the following procedure.
Step Inspection
Measure open circuit
1
voltage of battery.
Quick-charge for 30 min.
2
and recheck voltage.
Apply load test (see load
test chart) to battery using a
battery load tester and
3
record battery voltage after
15 s. Is voltage more than
specification?

Back-up Current
1. Verify that the engine switch is off and that the engine key has been removed.
2. Disconnect the negative battery cable.
Caution
• Operating electrical loads while measuring the back-up current can damage the circuit tester.
3. Measure the back-up current between the negative battery terminal and the negative battery cable.
(1) If the current exceeds the maximum, remove the fuses in the main fuse block and the fuse block one by
one while measuring the back-up current.
(2) Inspect and repair harnesses and connectors on the fuse where the current has been reduced.
Back-up current
20 mA max.
