Battery Removal (Fig. 36)
IMPORTANT: Be careful to not damage terminal
posts or cable connectors when removing the bat -
tery cables.
1. Disconnectthegroundcable(--)firsttopreventshort
circuitingthebattery,o thercomponentsortheoperators
hands. Then, disconnect the positive (+) cable.
2. Removetwo(2)wingnutsandbatteryholddownrod.
3. Make sure that the battery filler caps are on tightly.
4. Remove battery from the battery compartment to a
service area. This will minimize possible battery dam-
age and allow better access for inspection and service.
Battery Installation (Fig. 36)
IMPORTANT: To prevent possible electrical prob-
lems, install only a fully charged battery.
1. Makesuretheignitionswitchandallaccessoriesare
off.
2. Make sure the battery compartment is clean and re-
painted if necessary.
3. Make sure battery cables and battery retainer are in
good condition.
4. Place thebatteryinto batterytray.Make surebattery
is level and flat. Push the positive (+) cable connector
onto positive battery post. Do not hammer as this will
damage thebattery. Tighten cableclamp fasteners with
two (2) wrenches.
5. Install and securebattery hold downr od with two (2)
wingnuts.Do notovertightentopreventcracking ordis-
torting the battery case.
6. Connect a digital multimeter (set to amps) between
thenegativebatterypostandthenegative(--)cablecon-
nector. The reading should be less than 0.1 amp. If the
reading is 0.1 amp or more, the unit’s electrical system
should be tested and repaired.
7. Connect the negative (ground) cable connector to
thenegativebatterypost.Tightencableclampfasteners
with two (2) wrenches.
8. Coat terminals with battery terminal protector (see
Special Tools in this chapter) or a light coat of greaseto
reduce corrosion after connections are made.
