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.
