Pick-Up Coil: Testing and Inspection

Inspecting Air Gap:

Inspect Air Gap
- Using a thickness gauge, measure the air gap between the signal rotor and pickup coil projection.

Air gap: 0.2 - 0.4 mm (0.008 - 0.016 in.)

- If the air gap is not as specified. replace the distributor housing assembly.





Inspect Signal Generator (pickup Coil) Resistance
- Using an ohmmeter, measure the resistance between the terminals (G+ and G-, NE+ and NE-).

Pickup coil resistance (Cold):
G+ and G-
185 - 265 ohms at -10 - 40°C (14 - 104°F)
NE+ and NE-
370 - 530 ohms -10 - 40°C (14 - 104°F)

- If the resistance is not as specified, replace the distributor housing assembly.
