Help: I've been trying to track down a no-spark condition. All the checks I've done show that the Ignition Control Module is shorted to ground via the white (coil #1 wire), but the replacement unit I got reads the same. White wire from Ignition Module to coil is OK.

Findings:
1. HT Coil #15 to #1 terminals reads 1.8 ohms
2. HT Coil HT Lead to either #15 or #1 terminals read 800 ohms (*)
3. Power to Coil #15 when key on, slight voltage rise when cranking.
4. Distributor coil reads 1074 ohms.
5. Green & Brown wires from Distributor to Module plug has continuity and no
shorts to ground (I checked from both ends).
6. Black wire at Module plug to ground OK & aluminum Module frame to ground OK.
7. No voltage at Coil #1 connection when engine cranking, however there's a
momentary dim glow when the key is shut off.

(*) Shouldn't there be infinate resistance between the HT Lead terminal and the windings?

Does anyone know of a way to test the Ignition Control Module (P/N 0 227 100 018) function?

Anyway, suggestions welcome - thanks,

Paul
