Low Maintenance Battery Load Test

To prevent shock or component damage, remove spark
plug high tension leads and connect securely to engine
ground before proceeding.
NOTE: This test can only be performed on machines
with electric starters. This test cannot be performed
with an engine or starting system that is not working
properly.
A battery may indicate a full charge condition in the OCV
test and the specific gravity test, but still may not have
the storage capacity necessary to properly function in the
electrical system. For this reason, a battery capacity or
load test should be conducted whenever poor battery
performance is encountered. To perform this test:
1. Hook a multitester to the battery in the same manner
as was done in the OCV test. The reading should be
12.8 volts or greater.
2. Engage the starter and observe the battery voltage
while cranking the engine. Continue the test for 15
seconds.
3. During cranking the observed voltage should not
drop below 9.5 volts.
4. If the beginning voltage is 12.8 volts or higher and
the cranking voltage drops below 9.5 volts during the
test, replace the battery.

Low Maintenance Battery Charging
Procedure
1. Remove the battery from the ATV to prevent damage
from leaking or spilled acid during charging.
2. Charge the battery with a variable rate charging
output. Charge as needed to raise the specific
gravity to 1.270 or greater.
3. Install battery in vehicle with positive terminal toward
the front. Coat threads of battery bolt with a corrosion
resistant Nyogel® Grease (PN 2871329).
4. Route cables so they are tucked away in front and
behind battery.
5. Connect battery cables.
WARNING
To avoid the possibility of sparks and explosion,
connect positive (red) cable first and negative (black)
cable last.
6. After connecting the battery cables, install the cover
on the battery and attach the hold down strap.
