TESTING
Test battery voltage as follows:
1. Set the multimeter to 20 DC volts.
2. Connect multimeter leads to battery terminals, red
(+ POS) lead to positive terminal and black
(- NEG) lead to negative terminal (Figure 10D-1).
3. Crank the engine – if battery voltage falls below 9
volts while cranking, the battery is run down or
faulty. Charge and perform test again.
4. After charging, if battery still falls below 9 volts
when the engine is cranked, the battery is proba-
bly faulty and should be load tested and replaced
if necessary.
