PROCEDURE
DANGER
Park vehicle safely, apply parking brake, stop engine. Prior to working on the vehicle, set the ignition
switch to the OFF position and trip the main circuit breakers equipped with a trip button. On Commuter
type vehicles, set the battery master switch (master cut-out) to the OFF position.

MULTIPLEX SOFTWARE UPDATE
1. A Multiplex software update should be performed on the vehicle.
2. You must make an appointment at your nearest Prevost Service Center in order to receive the
software update. You can also contact your Prevost Service Representative for help.
2.
ELECTRICAL COMPONENTS – CORRECTIVE MEASURES
2.1
ALTERNATOR JUMPER CABLE INSPECTION / REPLACEMENT
RISK OF ELECTRICAL SHOCK
The alternator is connected to the batteries through master relay R1. If the ignition switch is in the OFF
position and the battery master switch (master cut-out) is set to the OFF position, there should not be
electrical power to the alternator terminals. However, a faulty master relay R1 could eventually leave the
battery power circuit closed, thus electrical power would be present at the alternator terminals.
Using a multimeter, probe the alternator B1+ terminal and the ground terminal. Make sure that the
voltage reading is 0 volt prior disconnecting the alternator cables.
1. Disconnect power cable A from the
upper alternator B1+ stud terminal.

2. Disconnect jumper cable B from the
upper alternator B1+ stud terminal.
To do so, unscrew and remove stud
adapter C and flat washer.
3. Disconnect jumper cable B from the
lower alternator B1+ stud terminal.
To do so, remove hex nut and
washer.

ADAPTER
4. Inspect the stud adapter that you
have just removed from the upper
alternator. The hex part of the stud
adapter must measure 1 inch long.
5. If the stud adapter hex part is too
short (about 13/16"), install stud
adapter #564590 included in kit
#7770176.
Using improper stud adapter leaves

6. Reinstall the jumper cable #067835 revision C included
in kit #7770176 (FIGURE 5, FIGURE 6).
Rev.C lug terminal through hole diameter= 5/16" CORRECT
Rev.B lug terminal through hole diameter= 13/32" INCORRECT
FIGURE 5
Rev.B diameter of the through hole is too large, reducing
contact surface with the stud and the nut thus reducing
electrical conductivity between the lug and the alternator
stud (FIGURE 7).

7. Reinstall appropriate jumper cable B
(i.e. rev.C) with appropriate stud
adapter. Refer to FIGURE 8.

1. Inside rear electrical compartment (rear
junction box), locate VECR module (FIGURE 10).
FIGURE 10 : VECR
2. Unplug connector no. 11 (green).
FIGURE 11
3. Using an extractor tool or a small flat blade
screwdriver, remove wire 24VDALT from cavity
H of connector no.11 (FIGURE 11 to FIGURE 14).
FIGURE- 12 : EXTRACTOR DELPHI 12094430
Remove the terminal by disengaging the flexible lock tab on the
terminal. Gently remove the terminal from the connector by
pulling on the wire.

4. Relocate wire 24VDALT to cavity C of
connector no.2 (red) on the harness.
Cavity C of connector no.2 should be available.
This branch of the circuit will be protected by 10A
fuse F64 (see FIGURE 16 below).
Should cavity C not be available, refer to your
vehicle wiring diagram page 5.1 to select
another free cavity protected by a 10A or 15A
fuse (see FIGURE 16 for reference).
IMPORTANT NOTE: If required, extend wire
24VDALT using 16 AWG red electrical wire in order
to reach connector no.2.
Cut and discard existing terminal. Extend wire
24VDALT by doing one soldered joint. Use the
included piece of heat shrinking sleeve to protect
the soldered joint. Place seal #12089679 at the end
of wire and crimp terminal #564055 (see FIGURE
15).
