NO SPARK OR INTERMITTENT ON ONE CYLINDER:
1. Check the DVA output on the green wires from the switch box while connected to the ignition coils. Check the reading on
the switch box terminal AND on the ignition coil terminal. You should have a reading of at least 150V or more at both
places. If the reading is low on one cylinder, disconnect the green wire from the ignition coil for that cylinder and reconnect
it to a load resistor. Retest. If the reading is now good, the ignition coil is likely bad. A continued low reading indicates a
bad switch box.
2. Check the trigger resistance and DVA output as shown below:
Wire Color Check To (Wire Color) Resistance DVA Reading
Brown wire White wire 800-1400 4V or more Connected
Brown wire Engine GND Open 1V or more (*)
White wire Engine GND Open 1V or more (*)
(*) This reading can be used to determine if a pack has a problem in the triggering circuit. For instance, if you have no fire on
one cylinder and the DVA trigger reading for that cylinder is low – disconnect the trigger wire and recheck the DVA output
to ground from the trigger wire. If the reading stays low – the trigger is bad.
3. Connect a inductive tach to each cylinder and compare the RPM readings at the RPM where the problem is occurring. If
only one cylinder is dropping out, swap the ignition coil locations and retest. If the problem follows a coil, replace the coil.
If it stays on the same spark plug, replace the switch box.
4. Check the flywheel magnets to see if one has come loose and moved."
