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 With Auxiliary (Booster) Battery
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 60.
WARNING
For your personal safety, use extreme care when jump starting.
Never expose battery to open flame or electric spark – battery
action generates hydrogen gas which is flammable and
explosive. Do not allow battery acid to contact skin, eyes,
fabrics, or painted surfaces. Batteries contain a sulfuric acid
solution which can cause serious personal injury or property
damage.
To avoid engine damage, do not disconnect battery while
engine is running. Be sure terminal connections are tight before
starting.

Make sure vehicles do not touch.
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.
