G pickup coil resistance:

G -> G-   

140 - 180 Ohms

Ne pickup coil resistance:

Ne -> G-   

140 - 180 Ohms

If the resistance is not correct, replace the distributor.

INSPECT AIR GAP

Using a thickness gauge, measure the gap between the signal rotor and the signal generators (pickup coils) projection.

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

If not, replace the distributor.
