Page 2: Installation Notes
INSTALLATION NOTES (Pro-Drag 250mJ Series 3 systems) MOUNTING Do not mount the unit where it will be exposed to water or other liquids, ensure the bottom condensation slots are unobstructed and oriented to permit gravity drain. Select a location away from intense heat and if required provide a source of cooling air. -
Page 3: Power Supply
installation/removal (use of dielectric grease in main connector may also reduce water ingress). POWER SUPPLY Do not use voltage boosters or connect through a PDM. If wired to a power source shared with the ECU or its sensors erratic operation may be experienced! If running a total loss electrical system install a 16V or 18V battery to ensure supply voltage is maintained above 13V. -
Page 4: Tacho Output
250mJ Pro-Drag systems with a trigger edge selection input default to falling edge ignition. To select rising edge ignition install a jumper wire between inputs ‘Trigger Edge’ and ‘Edge Ground’ pins. Where the ECU contains an inbuilt igniter it may be necessary to use rising edge ignition. -
Page 5: Installation Precautions
A repeated double flash of the LED may indicate a possible faulty ignition coil, faulty wiring, low supply voltage or damage to the CDI. TESTING The CDI may be tested by momentarily grounding the trigger inputs causing the LED to flash and corresponding ignition coil to spark. Do not conduct this test without grounded spark plugs installed! SAFETY Application of power to ignition system in combination with an... -
Page 6: Ignition Coils
IGNITION COILS (Pro-Drag 250mJ systems) COIL SELECTION For ultimate ignition energy use coils specifically designed for CDI use such as the M&W #COI006. Ignition coils primarily designed for inductive ignition will significantly limit CDI output. COP COILS COP (coil on plug) coils were not designed for the energy levels and voltage potentials developed by M&W Pro-Drag systems. - Page 7 Coil B + Coil C & D - PRO-DRAG4 160/250mJ S3 Size Number Revision Coil A + Coil D + Coil A & B - (C) M&W Ignitions 17.07.18.1 Date: 17-Jul-2018 Sheet of File: D:\M&W\..\Pro-Drag4 250 S3 SW 1.sch Drawn By:...
