Two plugs don't spark

[Tackster]

If the top two plugs of four do not work and the coils check out all right. Does that mean for sure that it is the switch box.

How do I check the trigger.

Re: Two plugs don't spark

if you don't have a manual and a DVA adapter, the easiest way would be to swap the trigger leads on the switch box and see if the dead cylinders follow. Then try swapping the charge leads. Don't attempt to start it, just check for spark....<br /><br />You should have a manual to guide you...

swap the trigger wires from the 3@4 to the 1@2 on the switch box.if still no spark,it not the triggers.check the stator.
