Ignition System Wiring

The engine will not start if the plug wires are connected to the wrong spark plug, or if one of the ignition unit red or white wires is reversed with another of the same color,. These wires are clearly marked as to left, right or center cylinder connection.

If the spark appears to be grounding out some where, examine the high voltage wires and replace any that have broken or clacked insulation. If no cracks are visible, run the engine in a dark place to see where the spark is jumping.

CAUTION:
Don't run the engine inside a closed area.

Any time wiring mistakes are suspected, in the ignition system or otherwise, check the wiring against the H2 wiring diagram shown below or H2 Wiring Diagram pages.
