John,
First check you have power to the coil by measuring voltage between either CB or SW and earth, should be something in the region of 6V (OK so far).
Then check continuity of the coil by measuring resistance
- between SW and CB should be 0.4 - 2 ohms
- between either contact and the HT terminal should be 6000 - 15000 ohms (mine was 8570 last week).
