CHECK

Voltage Check

1.

Disconnect the negative battery cable.

2.

Disconnect the ignition coil conntector.

3.

Turn the ignition switch to “ON"

4.

Measure voltage "B" at both of the white and the red wires at the ignition coil connector.

Voltage : approximately 12Volts

Resistance Check

1.

Using an ohmmeter, check the primary coil's resistance. If not with specification, replace coil.

Remember that the unit has two coil assembles, so there are two primaries to check. Connect one lead of the ohmmeter to the positive (＋) terminal and the other lead to each negative (-) terminal.

Primary coil resistance : 0.55 - 0.60Ω @ 68°F(20°C)

2.

Using an ohmmeter, check the secondary coil's resistance. If not within specification, replace coil.

Remember that you must check both the top and the bottem secondary coil's resistance. If one is out of specification replace whole unit.

Secondary coil resistance : 13―15kΩ @ 68°F(20°C)

Removal

1.

Disconnect the negative cable.

2.

Disconnect the high tension leads (4 each for SOHC ; 2 each for DOHC).

3.

Disconnect the ignition coil connector (1 each for SOHC; 2 each for DOCH).

4.

Remove the four ignition coil mounting bolts.

5.

Remove the ignition coils.

Installation

1.

Position the ignition coils

SOHC : Locate the coil so that the connector faces forward.

Locate the two coils above the #2 and #4 spark plugs, and firmly push down to connect.

2.

Insert and tighten the four coil mounting bolts.

Tighten bolts : 14-22lb·ft(19-30N·m)

3.

Reconnect the ignition coil connectors (1 each for SOHC; 2 each for DOHC).

4.

Reattach the high tension leads (1 each for SOHC; 2 each for DOHC). Be certain to make connections correctly; leads are marked.

5.

Reconnect battery cable.
