9/10 9000-0700 1 1 INSTALLATION INSTRUCTIONS for XR700 and XR3000 OPTICALLY TRIGGERED IGNITION SYSTEM Part Numbers 700-0226, 700-0231, 700-0292, 700-0300, 700-0309, 3000-0226, 3000-0231, and 3000-0292 For more information, see www.cranecams.com CAUTION: READ INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION. OVERVIEW XR700 and XR3000 electronic ignition modules use an opti- cal trigger assembly to replace conventional breaker points and original equipment (OE) magnetic and Hall Effect pickup systems. The XR700 requires ballast resistance to limit coil current. The XR3000 is a high performance version with a com- puter chip that controls coil current and dwell. When installing an XR3000, all OE ballast resistance must be bypassed. New XR700 and XR3000 modules have a diagnostic LED. All new XR700 units with the LED may be used for both negative or positive ground systems. These new XR700 units are not compatible with 6 volt systems. IGNITION INSPECTION The XR700/XR3000 optical trigger assembly requires an OE specification distributor cap and rotor to avoid clearance prob- lems and arcing. You should replace the rotor and cap when installing the new ignition system. For best results, you should also replace the spark plugs, spark plug wires, and ignition coil. Carefully inspect wiring to the coil and replace any worn or frayed sections. For maximum performance, use Crane coils and FireWire spark plug wires.

Mark distributor below number one spark plug terminal as shown in Figure 1. Remove distributor cap. Crank engine and note direction of distributor shaft rotation. 4. Align engine timing marks as specified in shop manual. If rotor is pointing opposite direction from mark, rotate engine one more complete revolution and align timing marks again. Timing marks must remain aligned throughout the installa- tion process. 5. Verify that rotor tip now points to the mark as shown in Figure 2. If not, loosen distributor tie down bolt and rotate distributor to align rotor tip to mark. Remember to tighten bolt when done. Note: Removal of distributor is not required, but may improve access. Follow instructions in shop manual. Mark engine where rotor tip is pointing. Do not crank engine with distributor removed. 6. Remove rotor and plastic dust shield (if used). Breaker point applications: remove breaker points, breaker post/stud, con- denser, and any wires from breaker points to coil or ground. Lucas only. If the distributor has a 3 terminal connector, it is an OPUS system and you can proceed. If the distributor has a 2 terminal connector, it is not an OPUS system and you must use Crane HI-6R part number 6000-6400.

    Study the ballast resistance sections carefully. Most installation problems result from improper ballast resistance.

    Quick Test for Ballast Resistance

    You can determine if your vehicle has external ballast resistance with this simple test. Disconnect any wires going to COIL-. Reconnect battery. Turn the ignition key on but do not start the engine. Use a volt meter as shown in Figure 23 and read voltage between COIL+ terminal and ground. It should be about 12 volts. Then momentarily jumper the COIL- terminal to ground. If voltage at COIL+ terminal drops below 8 volts, there is ballast resistance between the ignition key and COIL+ terminal. To determine if your coil has internal ballast resistance, use an ohm meter as shown in Figure 24. Coils with internal resistance will read 3 to 4 ohms from COIL- to COIL+ terminals.

    Figure 23. External Ballast Resistance Test

    Figure 24. Coil Resistance Test

    Figure 22. Terminal Removal

    If the XR700 runs very hot to the touch after 15 minutes of operation, you must add a ballast resistor.

    For maximum performance, any external ballast resistance must be bypassed. Refer to Figure 19. Locate external ceramic ballast resistor or resistance wire. Bypass it with heavy 14 AWG stranded wire. If this is not practical, refer to the Ignition Power Relay Tech Note in the Appendix on page 17.
