8. Verify if heating grips installation overloads the magneto / generator capacity
(ex: Élan).
a. Excessive electrical load to magneto / generator.
Reduce the electrical load by removing accessories.
SYMPTOM FALSE FUEL AND / OR TEMPERATURE GAUGE READINGS.
CONDITION NORMAL USE.
Test / Inspection 1. Verify if gauge was connected on DC current by mistake (in case of optional
installation).
a. Faulty installation of optional equipment.
Find optional wires connected directly to DC ground (BK wire to chassis) or to any DC hot
wire (RD, RD / BL). Disconnect and reconnect to AC current (YL and YL / BK wires).
2. Verify sender unit for free movement and / or correct arm position.
a. Defective or damaged part.
Correct or replace sender unit.
3. Verify sender unit / gauge wiring harness condition.
a. Heating, rotating or sharp part in contact with harness. Improper harness routing.
Replace or repair damaged wires. Reroute where necessary.
SYMPTOM ENGINES DOES NOT START – NO SPARK AT SPARK PLUG.
CONDITION AT ENGINE CRANKING.
Test / Inspection 1. Verify spark plug condition.
a. Defective, improperly set, worn-out, fouled.
Identify source of problem and correct. Replace spark plug.
2. Verify spark plug cap resistance with an ohmmeter.
a. Defective part.
Replace cap.
3. Verify if problem originated from electrical system wiring harness and / or ac-
cessories and / or ignition cut-out switches by unplugging the 4-wire connec-
tors between the magneto / generator and the vehicle wiring harness. Check
condition of connectors.
a. Heating, rotating or sharp part in contact with harness. Improper harness routing.
Defective switch(es). Corroded connector terminals.
Replace or repair damaged wires. Reroute where necessary. Replace defective
switch(es). Clean terminals and apply silicone dielectric grease.
4. Verify trigger coil resistance with an ohmmeter and connector condition.
a. Defective coil. Corroded connector terminals.
Replace defective coil. Clean terminals and apply silicone dielectric grease.
5. Verify condition of ignition coil.
a. Mechanically damaged part. Vibration problem. Electrically damaged part.
Tighten mounting screws. Replace ignition coil.
6. Verify condition of ignition generator coils.
a. Mechanically damaged part. Vibration problem. Electrically damaged part.
Tighten mounting screws. Replace coils.
7. Verify CDI (Capacitor discharge ignition) module.
a. Mechanically damaged part. Vibration problem. Electrically damaged part.
Tighten mounting screws. Replace CDI module, retest and verify ignition timing.
