So, I have assembled two spark rails both with two gaps, outside of the chambers wired up and connected to 3 point electric ignitor all gaps spark very efficiently, however when inserted into chambers the sparker favors one rail over the other. There are no earthing issues I'm aware of.
Both rails do work just not in unison.
Is there a possibility that the orange cable conduit and black plastic irritigation I'm using are conductive? That's the only thing I can think of, I don't even need to complete the circuit for the rail to spark inside the chamber, that's blowing my mind.

When you say three-point igniter do you mean it has three terminals? Also can we get some pictures or a diagram of what you have? It could be a lot of things but these are usually simple. :p

It's all sorted, sorry for the late reply I don't get notifications for some reason and have to check my posts for additional comments.
And yes a three terminal igniter for a bbq but I managed to sort it out, due to the length of the rails and the fine lines between earthing and not it favored one rail over the other but I tamed it.
