Jump Starting - PREVOST Le Mirage XL Owner's Manual

Jump Starting

Whenever it becomes necessary to start the
engine while batteries are discharged, use
another power source of the same voltage (24
volt DC), negative grounded and proper jumper
cables.
Warning:
Procedures other than the one
outlined could cause injury or damage from
battery acid spray, explosion, or charging
system overload.
- Never connect to the negative post of the
discharged battery.
- Never allow the two vehicles or the jumper
cable clamps to touch each other.
- Never attempt to jump start a vehicle if the
discharged battery fluid is frozen or if the
battery fluid level is low, as the battery may
rupture or explode.
- Do not jump start vehicles equipped with
maintenance-free batteries if the test indicator
is light yellow.
- Turn off all lights, heaters and other electrical
accessories. Make sure the parking brake is
applied and the transmission is set to
"NEUTRAL" before attempting to jump start
the engine.
- Wear eye protection and remove rings,
watches with metal bands and other metal
jewelry.
1. Connect one end of the red jumper cable to
the positive (+) post of the booster power
source.
2. On XL-40 & 45E vehicles, remove the gray
protective sealant from the 24 volt battery
disconnect switch post, then connect the other
end of the red jumper cable to this post
according to the illustration on page 4-18 (it
may be necessary to also remove the
insulating varnish on the battery switch
disconnect post).
2. On XL-45 vehicles, remove the red protective
cap from Booster Block's Positive Stud, then
connect the other end of the red jumper cable
to this stud (see illustration on this page).

overheating and will allow time delay relay to cool.
6. To remove the cables, perform the above
procedure in reverse order, then replace the
protective sealant, if possible.
Note:
Jumper cables must withstand 500
cranking amperes. If cable length is 20 feet (6
m) or less, use 2/0 (AWG) gage wires. If cable
length is between 20-30 feet (6-9 m), use 3/0
(AWG) gauge wires.
Note:
If, after doing this procedure, Starter
turns but Engine still doesn't run; (with Jumper
Cables in place) wait approximately 15 minutes
(to give battery equalizers time to balance 12V
and 24V charges), then try again. If engine still
doesn't run, repeat procedure once again.
