1. All connections must be of the highest quality, use crimped or soldered connections; twisted wires will not give a satisfactory operation. 2. Remove the petrol tank and/or seat to gain access to the ignition coils, condensors and wiring. 3. For safety, disconnect the battery (preferably both terminals). 4. Remove timing cover. (The Atlas engine has the points housing behind the cylinder head). 5. Disconnect the two wires (usually black-white & black-yellow) and remove the contact-breaker plate. At the other end, these two wires must be disconnected from the ignition coils & condensors. The condensors are no longer required and can be removed. They should not be connected to the electronic ignition system. 6. Remove auto-advance unit. 7. Disconnect the remaining wires from the ignition coils. These come from the ignition switch supply. On the Norton Commando, remove the white-blue wire from the ballast resistor between the two ignition coils; the ballast resistor is no longer required. The colour of this ignition supply wire may be different on some machines; if so check using a test lamp or meter to find the live wire when the ignition is switched on. 8. Find a suitable place for the ignition module, preferably near to the ignition coils. Secure the ignition module to the frame using one or more large cable ties. An adhesive mounting base is provided; this can be affixed to the underside of the module and the cable tie passed through and around the module and frame. Do not completely wrap the module in foam rubber. 9. Using the black coil link wire, connect the negative (—) terminal of one ignition coil to the positive (+) terminal of the other ignition coil. See figs. 1/2 on page 7. 10. Take the black wire from the ignition module, cut to length and fit an insulator and female spade connector to the end. Connect to the negative (—) terminal on ignition coil #2. See figs. 1/2 on page 7. 11. Take the red wire from the ignition module, cut to length and fit an insulator and female spade connector to the end. Connect to the positive (+) terminal on ignition • BLACK COIL LINK WIRE • RED EARTHING WIRE • CRIMP CONNECTORS & INSULATORS • LARGE & SMALL CABLE TIES • CABLE TIE ADHESIVE MOUNTING BASE 3 coil #1. See figs. 1/2 on page 7. 12. For NEGATIVE EARTH electrics go to step 15. 13. For POSITIVE EARTH electrics (standard): Take the white wire from the ignition module, cut to length and fit an insulator and male spade connector to the end. Connect to one of the negative ignition feed wires previously removed in step 7 (white-blue wire for Norton Commando). The other wire (if fitted) is spare and should be covered with insulation to prevent shorting to the frame etc. 14. Take the red earthing wire, fit an insulator and female spade connector on one end and connect to the positive (+) terminal on ignition coil #1. Cut to length and fit a ring terminal on the other end and connect to a good earth point on the frame, ideally the battery positive (+) terminal. For the Norton Commando, the earth tag on the end of the condensor pack can be used (fit a female spade connector to the end of the red earthing wire). See fig.1 GOTO STEP 17
