TESTING BATTERY

The specific gravity check method is listed in chart 2405. If alternator output is known to be correct, the
question of battery capability can be more accurately determined with a load type tester.

CHARGING BATTERY

If battery is not up to normal charge, remove and recharge it starting with a charging rate of 4 amps and
finishing with 2 amps. A fast charge is not recommended.
