ELECTROLYTE SPECIFIC GRAVITY
1. Measure the electrolyte specific gravity using a hydrometer.
z
If it is less than the specification, recharge the battery. (See
BATTERY RECHARGING [MZI-
3.5]
.)
Battery electrolyte specific gravity [20 °C {68 °F}]
1.22-1.29
BATTERY VOLTAGE
1. Inspect the battery as follows:
DIAGNOSIS PROCEDURE
Battery load test current
80D26L (55): 195 A
Standard specification
BATTERY SPECIFICATION
BACK-UP CURRENT
1. Verify that the ignition switch is off (key has been removed) and that all doors are closed.
Step
Inspection
Action
1 Measure the battery positive voltage.
12.4 V or
more
Go to Step 3.
Less than
12.4 V
Go to the
next step.
2 Quick charge for
30 min
and recheck voltage.
12.4 V or
more
Go to the
next step.
Less than
12.4 V
Replace the
battery.
3
Using the battery load tester, apply load current (80D26L (55): 195 A) and
record battery voltage after
15 s
. Is voltage more than the specification?
Yes
Normal
No
Replace the
battery.
