BATTERY TESTING
Voltmeter Test
See Table 7-21. The voltmeter test provides a general
indicator of battery condition. Check the voltage of the battery
to verify that it is in a 100% fully charged condition. If the
open circuit (disconnected) voltage reading is below 12.6V,
charge the battery and then recheck the voltage after the
battery has set for one to two hours. If the voltage reading is
12.7V or above, perform the load test.
Table 7-21. Battery Charge Conditions
Load Test
The load test measures battery performance under full
current load and is the best indicator of battery condition. To
load test the battery, proceed as follows:
IMPORTANT NOTE
Load testing a discharged battery can result in perma-
nent battery damage.
1. Always fully charge the battery before testing or test
readings will be incorrect. See BATTERY INSTALLA-
TION AND CONNECTION. Load testing a discharged
battery can also result in permanent battery damage.
2. After charging, allow battery to stand for at least one
hour before testing.
11WARNING1WARNING
Turn battery load tester OFF before connecting tester
cables to battery terminals. Connecting tester cables
with load tester ON can cause a spark and battery explo-
sion, which could result in death or serious injury.

3. See Figure 7-60. Connect tester leads to battery posts
and place induction pickup over negative (black) cable.
IMPORTANT NOTE
To avoid load tester and/or battery damage, do not leave
the load tester switch turned ON for more than 20 sec-
onds.
4. See Figure 7-60. Load battery at 50% of CCA rating
using the load tester. Voltage reading after 15 seconds
should be 9.6V or more at 70° F. (21° C).
Turn battery load tester OFF before disconnecting tester
cables to battery terminals. Disconnecting tester cables
with load tester ON can cause a spark and battery explo-
sion, which could result in death or serious injury.

5. Install the battery on the motorcycle. See BATTERY
INSTALLATION AND CONNECTION.
