FUSES

The snowplow electrical and hydraulic systems

contain several blade-style automotive fuses. If

a problem should occur and fuse replacement is

necessary, the replacement fuse must be of the same

type and amperage rating as the original. Installing a

fuse with a higher rating can damage the system and

could start a fire. Fuse Replacement, including fuse

ratings and locations, is located in the Maintenance

section of the Owner's Manual.

PERSONAL SAFETY

• Remove ignition key and put the vehicle in park or

in gear to prevent others from starting the vehicle

during installation or service.

• Wear only snug-fitting clothing while working on

your vehicle or snowplow.

• Do not wear jewelry or a necktie, and secure long

hair.

• Wear safety goggles to protect your eyes from

battery acid, gasoline, dirt and dust.

• Avoid touching hot surfaces such as the engine,

radiator, hoses and exhaust pipes.

• Always have a fire extinguisher rated BC handy,

for flammable liquids and electrical fires.

BATTERY SAFETY

CAUTION

Batteries normally produce explosive gases,

which can cause personal injury. Therefore,

do not allow flames, sparks or lit tobacco

to come near the battery. When charging or

working near a battery, always cover your

face and protect your eyes, and also provide

ventilation.

• Batteries contain sulfuric acid, which burns

skin, eyes and clothing.

• Disconnect the battery before removing or

replacing any electrical components.

OVERVIEW

The Isolation Module Tester performs continuity tests

on the 29070-1 and 29760-1 three-port isolation

modules for snowplow lighting systems.

SERVICEABLE PARTS

The tester simulates vehicle and snowplow low/high

beam, left/right turn signal, parking light, and control

power functions but does not simulate any load

conditions.

When the tester detects a continuity failure, the screen

display will identify the module component that is not

functioning. Record that information on your warranty

claim form and RMA tag.

The Isolation Module Tester is protected by internal

fuses. In the event of a short circuit or too much

current being drawn by the isolation module, the tester

will reset itself. There are no user-serviceable parts in

the Isolation Module Tester.
