Check the cap and outer shell for cracks.
Measure the resistance.
Spark plug cable | ||||
CYLINDER | No.1 | No.2 | No.3 | No.4 |
LENGTH | 560 | 440 | 360 | 310 |
RESISTANCE (BOUGI) Ω | 2.51~3.76 | 1.97~2.96 | 1.61~2.42 | 1.39~2.08 |
RESISTANCE (R16AIPS) Ω | 5.60~11.76 | 4.40~9.24 | 3.60~7.56 | 3.10~6.51 |
Resistance should not be higher than 10,000 Ω per foot of cable. If resistance is higher, replace the cable.
