Jump Starting With An Auxiliary (Booster) Battery - Simplicity Baron Operator's Manual

Jump starting with an auxiliary (booster) battery

Jump starting is not recommended. However, if it must be
done, follow these directions. Both booster and discharged
batteries should be treated carefully when using jumper cables.
Follow the steps below EXACTLY, being careful not to cause
sparks. Refer to the illustration.
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.
Any procedure other than the preceding could
result in:
(1) personal injury caused by electrolyte squirting out
the battery vents,
(2) personal injury or property damage due to battery
explosion,
(3) damage to the charging system of the booster
vehicle or of the immobilized vehicle.
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.
When removing or installing battery cables, disconnect the
negative cable FIRST and reconnect it LAST. If not done in
this order, the positive terminal can be shorted to the frame
by a tool.
To avoid engine damage, do not disconnect battery while
engine is running. Be sure terminal connections are tight
before starting.
