Stator, Fact or fiction

[61fish]

1985 V4 120hp.
I understand the stator provides the voltage to the power pack.

Is it true...If the stator is bad, you will no spark on two cylinders or no spark on all cylinders?

If this is true, Then if you have no spark on one cylinder, and you have eliminated a faulty plug, wire and/or coil, it almost has to be the powerpack?

Re: Stator, Fact or fiction

A weak failing stator could provide exellent spark when cold but erratic spark when hot, just exactly how erratic is unpredictable. A failed stator, completely failed, would result in no spark.

Check all of the wiring connections at the pins/sockets..... wires broken away from the pins/sockets, pins or sockets pushed slightly back into the rubber plugs resulting in poor connections, etc. This includes the connections between the timer base and the powerpack, and between the powerpack and the coils.

To check the powerpack circuitry to that one cylinder..... temporarily switch the timer base sensor lead that connects to the power pack, one that you know is firing some other coil, from that location to the location that should fire that non firing coil (without changing the coil wire to powerpack locations).

If the coil will now fire, the powerpack is okay and the problem would be either in the timer base to powerpack connector, OR the timer base, OR possibly the cranking speed of the engine.

The engine must crank over at least 300 rpm in order for the ignition to be energized.
