Ski-Doo Ski Doo GTX 2005 [677/1429] Warning

Section 04 ENGINE MANAGEMENT (SDI)

Subsection 03 (COMPONENT INSPECTION, REPLACEMENT AND ADJUSTMENT)

Voltage Test

WARNING

When disconnecting coil from spark plug, al-

ways disconnect coil from main harness first.

Never check for engine ignition spark from

an open coil and/or spark plug in the engine

compartment as spark may cause fuel vapor

to ignite.

Disconnect the plug connector from the ignition

coil and check the voltage supplied by the battery.

A32CA5A

Install tether cord cap on the DESS post and push

the START/RER button momentarily to activate

the ECM.

Check voltage between terminal 2 of ignition

coil connector on the wiring harness and battery

ground.

Battery voltage should be present (approx. 12 V).

If 12 V is NOT read, check continuity between ter-

minal 2 of ignition coil and the corresponding fuse.

Otherwise repair wiring harness.

If 12 V is read, disconnect the connector A from

the ECM and check the continuity of appropriate

circuit 41 (cylinder 1) or 1 (cylinder 2) and of igni-

tion coil connector, terminal 3 and terminal 1 re-

spectively.

If wiring harness is defective, repair the connector

or replace the wiring harness between ECM con-

nector and the ignition coil.

If wiring harness is good, test resistance of prima-

ry winding of ignition coil.

Resistance Test

Remove spark plug cables from ignition coil.

Using a multimeter, check the resistance of prima-

ry winding.

NOTE: The secondary winding can not be mea-

sured with an ohmmeter. Try a new double igni-

tion coil if necessary.

A32CCRA

1. Terminal 1a

2. Terminal 15

3. Terminal 1b

For primary winding, check the resistance be-

tween terminal 15 and terminal 1a (cylinder 1)

of the ignition coil and between terminal 15 and

terminal 1b (cylinder 2) respectively.

The resistance should be between 0.40 and

1.15

at 20°C(68°F).

If the resistance of one of both windings is not

good, replace the ignition coil.

If the windings test good, try a new ECM.



WARNING

Always reconnect ignition coil cables at the

same spark plugs where they come from.

Otherwise, severe backfire may occur with

possible damage to exhaust system compo-

nents.
