Rotor/Reluctor Phasing Question

The picture of the distributor shows perhaps an advance of 40 degrees based on the reluctor. A better guess if the picture was taken over the rotor shaft.

I think you have a phasing problem related to a swap of the pickup coil connections. I think the pictures shows a splice at the 2-wire connector. If the connections are reversed, both the timing and rotor phasing will be off in a way, that cannot be corrected by just setting distributor.

Reverse the connections, significantly re-time and you should be good.

Attached is a picture of a VR sensor signal (top) and ignition trigger(falling edge on bottom). The VR signal needs to go low then high, in your case the signal is flipped, creating a significant problem.

The other problem in phasing is often caused by the reluctor being installed wrong, one position for SB, the other for BB that has reverse rotation.


OK, now we're getting somewhere.... Is it possible to tell whether the timing would need to be advanced or retarded once I swap the wire connections..? Or do I just have to swap the connections and try to start the car and take it from there...
