Ignition System

ELECTRICAL SYSTEM

OThe hand tester cannot detect layer shorts and shorts resulting from insulation breakdown under high voltage.

• Disconnect the primary leads from the coil terminals.

• Measure the primary winding resistance [A] as follows: OConnect the hand tester between the coil terminals. OSet the tester to the × 1Qrange, and read the tester.

• Measure the secondary winding resistance [B] as follows: OPull the spark plug cap off the lead.

OConnect the hand tester between the spark plug lead and

black or green lead terminal. OSet the tester to the × 1 kQrange, and read the tester.

Ignition Coil Winding Resistance Primary windings: 2.6 ~ 3.1 П

Secondary windings: 13.5-16.5 kQ

• If the tester does not read as specified, replace the coil [C].

• If the tester reads as specified, the ignition coil windings are probably good. However, if the ignition system still does not perform as it should after all other components have been checked, test replace the coil with one known to be good.

• Check the spark plug leads for visible damage.

• If any spark plug lead is damaged, replace the coil.

Ignition Timing Inspection

• Remove the ignition timing inspection plug.

• Attach the timing light [A] in the manner prescribed by the manufacturer.

Special Tool - Timing Light: 57001-1241

Filler Cap Driver: 57001-1454

• Start the engine and aim the timing light at the ignition timing mark on the alternator rotor.

• Run the engine at the speeds specified and note the align­ment of the ignition timing marks.

Engine speed r/min (rpm) Notch [A] aligns with:
1500 and below F mark [B] on alternator rotor
