Installation Instructions
Page 1 of 1 II164B
To install filter assembly:
1. Disconnect battery wiring:
a. Disconnect vehicle battery master switch
and vehicle battery ground cable(s).
b. Remove cable from alternator B+ terminal
or affected component.
2. Set unit in mounting location on vehicle surface
already grounded in a location close to alternator
or affected component. Torque hardware to
8.5 Nm/75 lb. in.
Electromagnetic compatibility (EMC)/electromag-
netic interference (EMI) low and high frequencies
can interfere with the operation of electrical/
electronic systems, especially communication
equipment.
If diagnostic tests performed at system and
component level do not identify the source,
installing an EMC filter may help to reduce or
eliminate EMC condition.

NOTICE
EMC filter can be installed at
power supply of the affected
component or at the B+ terminal
on the alternator.
3. Connect red lead provided with kit.
NOTICE
The length of the cable
supplied with the filter has
been designed to reduce most
EMC conditions.
In severe EMC conditions,
shortening the cable may
optimize the filtering.
a. Larger terminal end to alternator B+ terminal
or component power terminal as shown in
stacking order. Torque terminal nut to torque
value specified by alternator model or compo-
nent manufacturer.
b. Smaller terminal end to terminal on filter.
Torque to 4.5 Nm/40 lb. in.
4. Reconnect vehicle battery master switch and
vehicle battery ground(s).
5. Operate engine and check alternator output or
component operation.
