Charging Procedure
1. Remove the battery to prevent damage from leaking
or spilled acid during charging.
2. Charge the battery with a ch arging output no la rger
th
an 1/10 of the ba ttery’s am p/hr ra ting. Charge as
needed to raise the specific gravity to 1.270 or greater.
3. Install battery in vehicle. Coat threads of battery bolt
with a co
rrosion resistant dielectric grease.
4. Connect battery cables.
5. After connecting the battery cables, install the cover
o
n the battery and attach the hold down strap.
6. Install clear battery vent tube from vehicle to battery
vent
. WARNING: Vent tube must be free from
obstructions and kinks and securely installed. If n ot,
battery gases co uld accumu late an d ca use an
explosion. Ve nt sho uld be routed away fro m fr ame
and bod y to prevent contact with e lectrolyte. Avoid
skin contact with e lectrolyte, a s severe burns could
result. If e lectrolyte contacts the veh icle frame,
corrosion will occur.
7. Route ca bles so th ey ar e tu cked awa y in fro nt an d
b
ehind battery.
STARTING SYSTEM
Troubleshooting
Starter Motor Does Not Run
• Battery discharged
• Loose or faulty battery cables or corroded
conn
ections (see Voltage Drop Tests)
• Related wiring loose, disconnected, or corroded
• Poor ground connections at battery cable, starter
moto
r or starter solenoid (see Voltage Drop Tests)
• Faulty key switch
• Faulty starter solenoid
or starter motor
• Engine problem - seized or binding (can engine be
r
otated easily)
Starter Motor Turns Over Slowly
• Battery discharged
• Excessive circuit resistance - poor connections
(see
Voltage Drop Test)
• Engine problem - seized or binding (can engine be
r
otated easily)
• Faulty or worn brushes in starter motor
Starter Motor Turns - Engine Does Not Rotate
• Faulty starter drive
• Faulty starter drive gears or starter motor gear
• Faulty flywheel gear or loose flywheel
Voltage Drop Test
The Voltage Drop Test is used to test for bad connections.
When performing the test, you are testing the amount of
voltage drop through the connection. A poor or corroded
connection will appear as a high voltage reading. Voltage
shown on the meter when testing connections should not
exceed 0.1 VDC per connection or component.
To perform the test, place the meter on DC volts and place
th
e meter leads across the connection to be tested. Refer
to th e volt age dr op te sts o n the starter system in this
chapter.
Dielectric Grease
(PN 2871329)
To avoid the possibility of explosion, connect
positive (+) cable first and negative (-) cable last.
Voltage should not exceed
.1 DC volts per connection
