Testing Ignition Coil

Ignition coil is located in distributor. Disconnect distributor 2-pin harness connector. Remove distributor cap. To check primary coil, measure resistance between distributor 2-pin connector terminals. To check secondary coil, measure resistance between ignition coil tower and distributor 2-pin connector terminal No. 8. See Fig 1. See IGNITION COIL RESISTANCE (G20) table.

IGNITION COIL RESISTANCE (G20)

Application

Resistance @ 77°F (25°C)

Primary ⁽¹⁾

About 0.8 Ohm

Secondary ⁽²⁾

About 16K/Ohms

⁽¹⁾	Measured between distributor 2-pin connector terminals.
