11.1 SAFETY INTERLOCK SYSTEM

Check the safety interlock system to make sure that it

is functioning properly. Rider must not start unless

speed selector is in neutral (N) and mower clutch is

disengaged (OUT). Engine MUST stop if operator

leaves seat when speed selector is in any drive

position or with mower clutch engaged (IN).

Interlock module grounds engine ignition if speed

selector and mower clutch switches are not closed.

Also, module will ground ignition if seat switch is not

closed when opening speed selector and mower clutch

switches.

11.2 TROUBLESHOOTING

Check that connections to switches are secure and that

switches are being activated properly before

performing electrical tests. (Safety switches on speed

selector and mower clutch levers may be out of

adjustment, not activating properly).

Check engine electrical function by disconnecting

Yellow wire (and Green wire on electric start models)

from engine. If engine has no spark, problem is in

engine (refer to engine repair manual).

If engine electrical system functions properly (has

spark) with wires disconnected, connect Yellow wire

(and Green wire on electric start model) to engine and

check that all wires of units electrical system are

connected properly (refer to electrical schematic).

IMPORTANT:

When checking switches electrically,

remove them from their respective circuits by

disconnecting the wires from the switch at the

connector(s) before testing or damage could result to

meter or interlock module.

To test a normally open key (recoil start models), safety

or seat switch, connect an ohmmeter across switch

terminals. Meter should indicate high resistance (open

circuit). Activate the switch. Meter should read up scale

to zero resistance (Closed Circuit) indicating switch is

operating properly. Check from each terminal to switch

case (if case is metal), reading should show high

resistance indicating no short to ground.

The ignition switch (on electrical start models) has

three positions; OFF, RUN and a momentary START

position.

In the OFF position, there should be continuity between

contacts "M" and "G".

In the RUN position, there should be no continuity

between contacts "B" and "S".

If after performing the above checks the engine does

not start, check interlock module by disconnecting it at

connector. This removes the module from electronic

ignition circuit, If engine starts, module is defective and

must be replaced.

11.3 BATTERY (ELECTRIC START

MODELS)

Every 25 hours or each week check electrolyte level of

each cell by removing caps one at a time. The

electrolyte level should be at level indicator. Use

distilled water to fill each cell if needed. Install and

tighten each cap after checking.

IMPORTANT:

When distilled water is added to battery

during freezing weather, it must be charged to mix

water with electrolyte or water will remain at top and

freeze.

Keep battery and its terminals clean. Inspect monthly

to be sure of obtaining best performance.

To clean terminals remove battery from unit by

removing cables. Remove battery strap and hooks and

lift battery out. Clean or service away from unit.

Remove corrosion from battery terminals and cable

connections with a wire brush, then wash with a weak

baking soda solution.

SECTION 11 - ELECTRICAL

DANGER:

Failure of interlock, together with

improper operation of unit, could result in

severe personal injury.

WARNING:

Batteries produce explosive

gases which can cause personal injury. DO

NOT allow flames, sparks or any ignited

object to come near battery. When charging

or working near a battery, always shield your

eyes and provide ventilation.

WARNING:

Keep batteries out of reach of

children. Batteries contain sulfuric acid. Avoid

contact with skin, eyes or clothing. In case of

acid contact with skin, eyes or clothing, flush

immediately with water for a minimum of 15

minutes. If acid is swallowed, drink large

quantities of milk or egg or vegetable oil. Call

a physician immediately.

WARNING:

DO NOT allow tools or other

objects to come into contact with both

terminals at same time. When removing

battery from unit, remove negative (-) cable

first to reduce risk of sparks.
