LOW MAINTENANCE
BATTERY INSPECTION/
REMOVAL
The battery is located under the seat.
1. Remove the seat and Disconnect holder strap.
2. Disconnect battery negative (-) (black) cable first,
followed by the positive (+) (red) cable.
CAUTION
Whenever removing or reinstalling the battery,
disconnect the negative (black) cable first and
reinstall the negative cable last!
3. Remove the battery.
LOW MAINTENANCE
BATTERY INSTALLATION
1. Clean battery cables and terminals with a stiff wire
brush. Corrosion can be removed using a
solution of one cup water and one tablespoon
baking soda. Rinse well with clean water and dry
thoroughly.
2. Route the cables correctly.
3. Reinstall battery, attaching positive (+) (red) cable
first and then the negative (-) (black) cable. Coat
terminals and bolt threads with Nyogelt Grease

BATTERY TESTING

Whenever a service complaint is related to either the
starting or charging systems, the battery should be
checked first.
Following are three tests which can easily be made on
a battery to determine its condition:
Specific Gravity Test and Load Test.
LOW MAINTENANCE
BATTERY - - OCV - OPEN
CIRCUIT VOLTAGE TEST
Battery voltage should be checked with a digital
multitester. Readings of 12.8 volts or less require
further battery testing and charging. See charts and
Load Test.
NOTE: Lead-acid batteries should be kept at or near
a full charge as possible. If the battery is stored or
used in a partially charged condition, or with low
electrolyte levels, hard crystal sulfation will form on
the plates, reducing the efficiency and service life of
the battery.
NOTE: Use a voltmeter or multimeter to test batter
voltage.
