NOTE
Secondary Test
The engine will misfire if the spark plug wires are
installed incorrectly. The spark plug wires are marked
with PTO and MAG from the factory and should be
installed to the corresponding cylinder and ignition coil
post.

1. Remove the seats and engine service panel to
access the ignition coil.
2. Disconnect the ignition coil harness and remove the
high tension leads from the coil.

3. Remove the fastener retaining the ignition coil and
remove it from the vehicle. If replacing the high
tension lead(s), remove the other end of the lead(s)
from the spark plug.
4. Install the new ignition coil and/or high tension lead
(s).
