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 54.
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 batter-
ies 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 dis-
charged 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 vehi-
cle away from battery. Do not lean over batteries.
8. Start the engine of the vehicle with the booster bat-
tery. 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 sec-
onds seldom starts the engine unless some mechani-
cal 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 dis-
charged battery first and then disconnect the oppo-
site end from the booster battery.
12. Discard the damp cloths that were placed over the
battery vent caps.
