Sparking; Electrical Connector Testing; Ignition Switch, Tether Cord Switch And Engine Cut-Out Switch Testing - BOMBARDIER ski-doo Tundra Scandic 2004 Series Shop Manual

Section 06 ELECTRICAL
Subsection 06 (TESTING PROCEDURE)

1. SPARKING

During this operation, it is important to use the
snowmobile spark plug and not a new one. Bring
the plug in contact with the engine. If no spark is
produced, replace the spark plug with a new one
and do the test again.
2. ELECTRICAL CONNECTOR
TESTING
Make sure that none of the connectors are discon-
nected.
3. IGNITION SWITCH, TETHER
CORD SWITCH AND ENGINE
CUT-OUT SWITCH TESTING
Disconnect connector housing from engine, and
using a multimeter, check resistance as indicated
in IGNITION table.
If readings are acceptable, go on to next step.
If readings are inadequate, individually check each
switch as follows.
Ignition Switch (key)
Disconnect switch housing. Using a multimeter,
check between MAG and GRD terminals if the cir-
cuit is open (0.L ) in operating position and if the
MΩ
circuit is closed (0 ) in off position.

TYPICAL
If readings do not correspond to the above-
mentioned indications, replace switch.
If readings are acceptable, check other switches.
Engine Cut-Out Switch
Unplug switch block connected to main wiring har-
ness. Check using a multimeter. Connect probes
to terminals. The multimeter should indicate an
open circuit (0.L ) in operating position and a
MΩ
closed circuit (0 ) in off position.

If readings do not correspond to the above-
mentioned indications, replace switch.
If readings are acceptable, check other switches.
