ELECTRICAL SYSTEM A 12 volt electrical system is required. Check that the charging system is working properly and not producing over 16 volts. DISTRIBUTOR CLAMP A 1966-69 style distributor clamp (original or aftermarket) is required. MODULE This distributor uses an Accel Single/Dual Fire Ignition module part number 35496. See the enclosed form “Instruction Sheet Single/Dual Fire” for instructions on wiring, adjusting the rev limiter and selecting an advance curve. COIL(S) A coil(s) with a total primary resistance of 2 to 4 ohms is recommended. INSTALLATION Step 1 Turn the ignition switch to the off position. Rotate the engine until it is on the compression stroke for the front cylinder. Continue to rotate the engine until the TDC mark is visible through the timing hole. (see repair manual if necessary). Step 2 Remove the existing distributor if still in the engine. Step 3 Remove the two button head screws from the top of the Mallory distributor. Pull the top cover off the distributor. Remove the two hex standoffs and pull the module and upper housing off the distributor base assembly. Adjust the switches on the module for the desired advance curve and rev limit. FORM 1627 07/08 Step 4 Install the distributor base assembly in the engine with the screw holes and shutter wheel positioned as shown in Figures 1 and 2. It may be necessary to pull the distributor out, turn the shaft and reinstall to get the shutter wheel at the approximate angle shown. The slots should be at about the11 o’clock and 7 o’clock positions. The screw holes should be at the 9 o’clock and 3 o’clock positions. Step 5 Install the distributor clamp and tighten the clamp bolt lightly so the distributor can still be rotated. Step 6 Set the upper housing on the base assembly as shown in figure 3. (The upper housing will only install one way because of the locating screw) Rotate the base assembly slightly if necessary so that the slot in the shutter wheel lines up with the slot in the upper housing. Tighten the distributor clamp

Turn ignition switch to the OFF position. Disconnect the ground cable from the battery. 2) Disconnect the wire at the coil which runs down to the points. Remove the point cover plate. 3) Note the position of the slots in the point plate. When the Mallory UNILITEfi plate is installed, use the position of the slots to approximate the timing. 4) Remove the wire to the points. Remove the O.E. standoffs and washers. Remove the point plate assembly. 5) Remove the O.E. cam sleeve from the advance assembly. Place a small amount of oil on the advance shaft which supported the cam sleeve. 6) Slide the Mallory shutter wheel onto the advance shaft. Make sure the shutter wheel is all the way down into the advance assembly (it will only go one way due to the roll pin in the advance assembly). 7) Install the advance and shutter wheel into the nose cone. Make sure that the pin on the bottom of the advance engages the slot on the end of the camshaft. Apply Loctite to the threads and install the advance bolt. Torque to 25 in.lb. 8) Rotate the shutter wheel by hand (counter-clockwise) and release. It should rotate about 10 degrees and “snap” back when released. 9) Install the two Mallory standoffs. Place Loctite on the threads and torque to 16 in.lb. Do not use any washers with the standoffs. 10) Start the three wires of the Mallory UNILITEfi Module through the hole in the nose cone housing. (The module goes in towards the advance assembly with the flat plate outward). Pull on the three wires to remove any slack and prevent the wires from rubbing on the shutter wheel. 11) Rotate the UNILITEfi plate assembly until the slots in the plate are in the same position as the point plate was. This should make the timing close enough to start the engine. Slide the two Mallory 8-32 sleeve nuts (supplied) through the UNILITEfi plate and onto the male threads of the Mallory standoffs. Tighten the sleeve nuts just enough to prevent the plate from moving. 14) Route the wires from the UNILITEfi Module to the ignition coil, carefully avoiding the exhaust system. Connect the red wire to the positive (+) terminal (12 volts) on the coil. Connect the green wire to the negative (ñ) terminal on the coil (where the point wire was connected). Connect the brown wire to ground. The best place for the brown wire is the negative (ñ) post on the battery, however, any part of the frame or engine which is grounded to the battery will work

Programming the RPM The engine application and rpm activation points are easily selected through push buttons on the LED panel. This Switch can be programmed for a variety of engine and ignitions as shown below. 1-Cylinder This program is used for individual coil per cylinder systems (such as GM LS-1 engines, or ’99-Up Mustangs) 2-Cylinder This is for ignitions with coil packs that fire two cylinders at the same time (waste spark systems) 2-Cyl. Odd Use on coil pack ignitions that are on odd-fire engines such as a Viper V-10 or Harley-Davidson motorcycle. 4-Cylinder Typical 4-cylinder engines with a distributor. 6-Cylinder Typical 6-cylinder engines with a distributor. 6-Cyl. Odd Typical 6-cylinder odd-fire engines with a distributor. 8-Cylinder Typical 8-cylinder engines with a distributor. 1.2 Push Button LED Panel The rpm activation points and cylinder select are programmed through the push buttons on the LED panel (Figure 1) . Press the Mode button, and notice that the indicator point above the On RPM lights. When that point is on, you can scroll the rpm value up or down with the arrows on the left of the panel. Once your On rpm is set, push the Mode button until the Off RPM point lights, then set the off rpm point. Note that if the rpm point is not changed within 2-seconds, the screen returns to the current rpm reading (zero when the engine is not running). After setting the On and Off points, press the Mode button to program the Cylinder Select Valve (default is for 8-cyl.

Step 1: Apply a thin coat of silicone grease to the bottom of the module before mounting the module to its plate in the distributor. Step 2: Slide the three wires from the MODULE, through the grommet, to outside the distributor housing. Put the three wires from the MODULE in the TERMINAL PIN HOUSING: GREEN WIRE in hole #1, BROWN WIRE in hole #2, RED WIRE in hole #3. Plug the three wire harness (PN 29349, not supplied with this kit) into the TERMINAL PIN HOUSING. RED WIRE: Power/voltage for the MODULE. Connect to coil (+) terminal. GREEN WIRE: Ignition trigger. Connect to coil (-) terminal. BROWN WIRE: Ground for the MODULE. Connect to ENGINE BLOCK GROUND. Clean away any grease, oil, and paint from the mounting surface before the connection is made.

Harley Davidson has manufactured 9 types of engines from 1929 to the current model. Flathead (1929-1974), Knucklehead (1936-1947), Panhead (1948-1965), Shovelhead (1966-1984), Evolution (Blockhead) 1340 (1984-1999), Big Twins 1450 (2000 to current), Revolution/V-Rod (2001 to current) Ironhead Sport- sters (1957-1984) & Evolution Sportsters 1985 to current. Harley Davidson recommends SAE 50 or 60 for the engine oil in their Flathead, Knucklehead, Panhead, and Shovelhead. AMSOIL recommends AHR SAE 60 or MCV 20W-50 motorcycle oil for all these older models. Use AMSOIL SVG or SVO for the transmissions. Of these models only the Shovelhead has a chain case that is lubed, and is fed by the engine oil. In the Evolution 1340, Big Twins 1450, and V-Rods, AM- SOIL recommends MCV 20W-50 motorcycle oil in all 3 holes (engine, transmission, and primary chain case). AMSOIL recommends SVG as an alternative oil for the transmission, and SVO as an option for older transmissions. New seals are recommended where excessive leaking exists.
