SECTION 3

IN CASE OF DRIVING EMERGENCY

JUMP STARTING

If your coach will not start from the automo-

tive batteries, try using the aux. start switch to

divert power from the coach batteries to the

starter. (See Aux. Start Switch on page 2-14.) If

you wish to try jump starting the engine using

another vehicle or booster system, here are basic

guidelines for connecting jumper cables to auto-

motive electrical systems.

CONNECTING JUMPER

CABLES

1. Make sure that the other vehicle has a 12-

volt battery and negative ground compatible

with your vehicle’s electrical system.

2. Position the vehicle with the good battery so

that the jumper cables will reach, but do not

allow the vehicles to touch.

3. Turn off all electrical accessories, motors,

and lights except those needed for safety or

to light up the work area. Place automatic

transmission in N (Neutral) and apply park-

ing brake. Be sure parking brakes are

engaged in both vehicles.

4. If the weak battery has filler caps, make sure

the electrolyte is at proper level. Add dis-

tilled water if fluid is low. If electrolyte is not

visible or appears to be frozen - do not

attempt jump starting! A battery may rup-

ture or explode if the electrolyte is frozen or

not filled to the proper level.

5. Connect one end of the positive “+” (red)

jumper cable to the positive “+” terminal of

the weak battery. Connect the other end to

the positive “+” terminal of the charged bat-

tery.

6. Connect one end of the negative “-” (black)

jumper cable to the negative “-” terminal of

the charged battery.

7. Finally, connect the remaining end of the

negative “-” (black) cable to a solid, metal

grounded location on the engine of the vehi-

cle with the weak battery, at a point at least

18 inches from the battery. Do not connect to

any moving parts. THE MAIN SAFETY

PRECAUTION IS TO MAKE THE FINAL

GROUND CONNECTION ON THE

ENGINE AT A SAFE DISTANCE FROM

THE BATTERY. THIS HELPS TO

REDUCE THE CHANCE OF EXPLO-

SION DUE TO SPARKS.

8. Start the engine of the vehicle with the

charged battery, and allow it to run for a few

minutes at moderate r.p.m. Then start the

engine of the vehicle with the discharged

battery.

9. Reverse the above sequence EXACTLY

when removing the jumper cables. Start by

removing the cable from the ground location

on the engine first, then continue in reverse

sequence.

WARNING

Automotive batteries produce caustic

acid, explosive gases, and electrical

current which may cause burns. It is

important that the instructions below

are followed exactly, or personal

injury (particularly to eyes) or prop-

erty damage may result due to battery

explosion, battery acid, or electrical

(short circuit) burns.

• NEVER smoke near the battery or

expose it to open flame or electri-

cal sparks.

• Wear eye protection or shield

your eyes while working near bat-

tery, in case an explosion does

occur. NEVER lean over a bat-

tery.

• Do not allow battery fluid to con-

tact eyes, skin, clothing, or

painted surfaces. Immediately

flush any contacted area with

water. If eyes are affected, seek

medical help after flushing.

• Remove all metal jewelry to

lessen the risk of a short circuit

occurring.
