Ignition System Testing - Polaris Outlaw 500 Service Manual

Ignition System Testing

Whenever troubleshooting an electrical problem you should first check all terminal connections to be sure they are clean and tight.
Also be sure that colors match when wires are connected. Use the following pages as a guide for troubleshooting. The resistance
values are also given on the specification pages.
Condition: No spark or intermittent spark.
Verify 12 Volt DC power is present on the red wire to CDI. Replace Spark Plug.
Disconnect the black wire from the 4 wire connector
attached to the CDI module to isolate the ignition
from the kill system. Verify the CDI has a good
ground path (brown) for operation.
Does it have spark?
Disconnect the pulse (trigger) coil connector from
the CDI module. Measure the resistance of the
trigger coil. Check reverse signal coil. Refer to the
exploded view or the wiring schematic for meter
connections and specifications.
Compare results to the specifications.
Is it within specification?
Check coil ground connection between engine and coil
mount using an ohmmeter. The coil mount should
have good continuity to ground on the engine (0 - .3 Ω
Disconnect and check the secondary coil.
Resistance values should be:
Primary Side - Primary wire tab to engine ground
(on coil mount or engine): .3 to .5 Ohms
Secondary Side High Tension wire to engine ground
Cap installed - 11,300Ω
Cap removed - 6300Ω
Are these values within specs?
If all of the above tests are within specifications, and all grounds, connections, and wire color coding
have been inspected, perform voltage output tests on following page or replace the CDI module.
