SINGLE FIRE IGNITION COIL

INSTALLATION INSTRUCTIONS for

SINGLE FIRE IGNITION COIL Part Number 8-3001

CAUTION: READ INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION.

INTRODUCTION

SPARK PLUG AND WIRE CONSIDERATIONS

The Crane Cams Single Fire Ignition Coil part number 8-3001 is intended for Harley-Davidson® applications with aftermarket single fire ignitions such as the Crane HI-4 series that require a 3 ohm resistance coil. The 8-3001 is molded in solid epoxy to eliminate vibration and arcing damage. The coil windings are computer designed to give increased energy, longer spark duration and higher current at the spark plug.

Crane FireWire spiral core spark plug wires or equivalent suppression wires are recommended for best performance. Do not use non-suppression solid core spark plug wires; they may cause interference with your ignition system and accessories. Use resistor (suppression type) spark plugs. Non-resistor spark plugs may cause interference with the computer in the ignition system.

WARNING: Do not perform any work or disconnect any part of the ignition system without first disconnecting the battery ground cable.

COIL MOUNTED UNDER FUEL TANK OR AT FRONT OF MOTOR ON FRAME DOWN TUBE 1. Refer to Figure 1 for coil mounted under fuel tank or Figure 2 for coil mounted on frame down tube.

WARNING: Do not come into contact with the coil primary wires or the secondary plug wires while the engine is running. Do not connect a timing light or other test equipment to any coil terminal while the engine is running. Never crank the engine with any coil high voltage terminal disconnected.

2. Disconnect the negative cable from the battery. 3. Refer to your shop manual for procedure to remove the fuel tank and any other accessories that may limit access to the coil. 4. Disconnect the original equipment (OE) wire harness going to the coil. Next, remove the OE coil. 5. Install the new coil as shown in Figure 1 or 2.
