17. BATTERY/CHARGING SYSTEM                        MXU 500 IRS


 BATTERY CHARGING

 Remove the battery (see page 17-5).

 Connect the charger positive (+) cable to the
 battery positive (+) terminal.
 Connect the charger negative (-) cable to the
 battery negative (-) terminal.
 Turn the power ON/OFF at the charger,
   not at the battery terminals.
 Charging current time:
        Standard:    1.8 A/510 hours
        Quick:       9 A/1 hours

 Quick charging should only be done in an
 emergency; slow charging is preferred.
 For battery charging, do not exceed the
 charging current and time specified on the
 battery. Using excessive current or extending
 the charging time may damage the battery.

 CHARGING SYSTEM
 INSPECTION

 CURRENT LEAKAGE TEST
 Turn the ignition switch OFF, disconnect the
 negative (-) cable from the battery.
 Connect the ammeter (+) probe to the
 negative (-) cable and the ammeter (-) probe
 to the battery (-) terminal.
 With the ignition switch OFF, check for
 current leakage.
 When measuring current using a tester, set it
 to a high range, and then bring the range
 down to an appropriate level. Current flow
 higher than the range selected may blow out
 the fuse in the tester.
 While measuring current, do not turn the
 ignition switch ON. A sudden surge of
 current may blow out the fuse in the tester.
 Specified current leakage: 0.5 Ma max.

 If current leakage exceeds the specified value,
 a shorted circuit is likely.
 Locate the short by disconnecting
 connections one by one and measuring the
 current.
