I was working on my 67 negative earth mgb and suspected a faulty ignition coil. Took the one from the rover, hooked it up and sure enough I was right. I put the coil back into the rover and now I'm not getting any spark from it. I borrowed another coil from another car and no luck with that either. I suspect that I have goofed up the wiring.

I had 5 wires hooked up the ignition coil. Black ground, white wire, white wire with green tracer, and two white wires with black tracers. Can somebody tell me which post to hook each of these up to.

 

The red and blue wires from the distributor pass through the ignition control module and turn into the white and white with black tracer wires. I was using a multimeter on the control module to identify which is which and I don't get flow through either wire. Is this a sign of a bad module or is there something else I'm missing?

 

The WB wires both connect to the Coil (-), the white and white/blue wires connect to the coil (+).

The black ground wire... if you have a condenser attached (little cylinder with 1 wire), it should connect to that. If not, run that wire to the coil bracket itself.

Best of luck.
