Motor is a 1986 2.4 bridgeport Mod vp. Recently rebuilt and electronics updated. Original stator. Symptoms are hard starting. This condition existed before the rebuild. Sometimes starts right up and other times is very hard to start. A lot of firing with kicking the starter out. Checked the stator and found that the two red wires are okay and the blue/white wire is okay although the resistance is lower than specs. The other blue wire is an open circuit.
I understand the blue wires support the low speed windings and the red support the high speed. Since the motor runs perfectly at speed, I suspect the stator is the problem.
My question is why does the motor even run at low speeds (once it starts) if one bank is not getting spark?

It is running on one bank untill around 2200 rpms,when the high speed windings take over,Chris

Would it not be very obvious that the motor was running on one bank? The motor seems to idle okay. That is, it does not shake or sound rough in any way.

I agree...just don't be standing in the water when you pull the plug wires...ask me how I know.:eek::eek::eek::nonod:

Well I replaced the stator today. Motor started okay on the trailor but won't know if all is okay untill next week when I will be at the lake. Thanks for the replies.
