A voltmeter can be used to determine condition of battery. 
When engine is off, the voltmeter shows battery voltage, 
which should be 12 volts. When engine is running, the 
voltmeter shows voltage of charging circuit which normally 
is 13 to 14 volts.

A dead battery or one too weak to start the engine may not 
mean the battery needs to be replaced. For example, it may 
mean that the alternator is not charging the battery properly. 
If there is any doubt about the cause of the problem, see 
your dealer. If you need to replace the battery, follow the 
steps under Cleaning the Battery & Cables in the Regular 
Maintenance Section.

 1.  Be aware of all the safety precautions you should 

observe during the charging operation. If you are 
unfamiliar with the use of a battery charger and 
hydrometer, have the battery serviced by your dealer.

 2.  Add distilled water sufficient to cover the plate (fill to the 

proper level near the end of the charge). If the battery 
is extremely cold, allow it to warm before adding water 
because the water level will rise as it warms. Also, an 
extremely cold battery will not accept a normal charge 
until it becomes warm.

 3.  Always unplug or turn the charger off before attaching 

or removing the clamp connections.

 4.  Carefully attach the clamps to the battery in proper 

polarity (usually red to [+] positive and black to [-] 
negative).

 5.  While charging, periodically measure the temperature of 

the electrolyte. If the temperature exceeds 125° F (51.6° 
C), or if violent gassing or spewing of electrolyte occurs, 
the charging rate must be reduced or temporarily halted 
to prevent battery damage.

 6.  Charge the battery until fully charged (until the specific 

gravity of the electrolyte is 1.250 or higher and the 
electrolyte temperature is at least 60° F). The best 
method of making certain a battery is fully charged, but 
not over charged, is to measure the specific gravity of 
a cell once per hour. The battery is fully charged when 
the cells are gassing freely at low charging rate and less 
than 0.003 change in specific gravity occurs over a three 
hour period.

Jump starting is not recommended. However, if it must be 
done, follow these directions. Both booster and dis-charged 
batteries should be treated carefully when using jumper 
cables. Follow the steps below EXACTLY, being careful not 
to cause sparks. Refer to Figure 49.

 1.  Both batteries must be of the same voltage.

 2.  Position the vehicle with the booster battery adjacent to 

the vehicle with the discharged battery so that booster 
cables can be connected easily to the batteries in both 
vehicles. Make certain vehicles do not touch each other.

 3.  Wear safety glasses and shield eyes and face from 

batteries at all times. Be sure vent caps are tight. Place 
damp cloth over vent caps on both batteries.

 4.  Connect positive (+) cable to positive post of discharged 

battery (wired to starter or solenoid).

 5.  Connect the other end of same cable to same post 

marked positive (+) on booster battery.

 6.  Connect the second cable negative (-) to other post of 

booster battery.

 7.  Make final connection on engine block of stalled vehicle 

away from battery. Do not lean over batteries.

 8.  Start the engine of the vehicle with the booster battery. 

Wait a few minutes, then attempt to start the engine of 
the vehicle with the discharged battery.

 9.  If the vehicle does not start after cranking for thirty 

seconds, STOP PROCEDURE. More than thirty seconds 
seldom starts the engine unless some mechanical 
adjustment is made.

 10. After starting, allow the engine to return to idle speed. 

Remove the cable connection at the engine or frame. 
Then remove the other end of the same cable from the 
booster battery.

 11. Remove the other cable by disconnecting at the 

discharged battery first and then disconnect the opposite 
end from the booster battery.

 12. Discard the damp cloths that were placed over the 

battery vent caps
