3-4 Replacing spark plug cap and coil
1. Disconnect spark plug cap from spark plug.
Remove spark plug cap cover from spark plug cap.
2. Apply some oil in spark plug cap (A) to aid in
removing spark plug cap from high tension lead (B).
3. Pull spark plug cap away from high tension lead.
4. Check spark plug cap coil (C) for correct
connection and corrosion. Check spark plug cap for
cracks. Replace as required.
NOTE: Make sure that spark plug cap coil contacts
conductor core of high tension lead when re-
installing it.
5. Apply oil to spark plug cap and insert high tension
lead as shown until spark plug cap coil is properly
seated in the cap.
3-5 Checking coil resistance
1. Connect one probe of an ohm-meter or a
multimeter to spark plug cap coil and the other end
to some part of cylinder.
2. Measure secondary coil resistance. Resistance
should be in the range of 2.5 to 3.2 kΩ; if the value
is not in the range, replace with a new ignition coil.
