NOTE
Material can be obtained through regular channels.

PROCEDURE

DANGER
Park vehicle safely, apply parking brake, stop the 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.

NOTE
YOUR VEHICLE MAY ALREADY HAS THE APPROPRIATE STUD ADAPTER.

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.

DANGER
Using a multimeter, probe the alternator B1+
terminal B1+ and the ground terminal. Make
sure that the voltage reading is 0 volt prior
disconnecting the alternator cables.

INSPECTION
1. Remove existing hexagonal locknut E, flat
washer D and power cable A from the stud
adapter.

NOTE
The existing locknut must be replaced as it
is one-time use only.
The existing M8 nut « E » #5001787 is
canceled and replace by nut #5001983.

2. Discard old locknut E.

FIGURE 2

3. Clean the anti-corrosion compound that was
applied on the stud adapter B especially
between flats.

Figure 3
4. Inspect the distance between flats on the stud
adapter. There are only two possibilities; 1/2’’
or 5/8’’.
5. First, use a 1/2’’ open wrench and check if
you can engage the wrench between the flats
of the stud. If you cannot engage the 1/2’’
open wrench on the stud, try a 5/8’’ open
wrench and check if you can engage this
second wrench between the flats of the stud
and if it fits tight.

Figure 4

NOTE
Ensure step 5 is done properly as it will
impact the following steps.

6. If the distance between flats is 5/8’’, you have
the correct stud. Move to step 7.
If the distance between flats is 1/2’’, you have
the wrong stud and you need to change it.
Move to step 10.
