System Specifications

If the resistance of any spark plug wire exceeds following ranges, replace the spark plug wire being tested:
^ 0 - 380 mm (0 to 15 in) long wire = 0 - 750 Ohms.

^ 380 - 635 mm (15 to 25 in) long wire = 0 - 1,250 Ohms.

^ 635 - 889 mm (25 to 35 in) long wire = 0 - 1,750 Ohms.

For longer wires, the measured resistance should not exceed approximately 1,968 Ohms per meter (600 Ohms per foot).

If the ohmmeter reads above 2,400 Ohms, no matter how long the wire is, or fluctuates from infinity to any value, replace the spark plug wire.
