Ignition Wire Resistance
- Set ohmmeter to x1000 range and attach leads to each end of high tension wire. On Isuzu I-Mark (RWD) and P'UP, resistance should be 3150-73,500 ohms per foot.
- On Isuzu I-Mark (FWD), see IGNITION WIRE RESISTANCE table. On all other models, resistance should not exceed 25,000 ohms per wire. If it does, replace wires.
