Ford Big Block DIS8-BBF Distributorless Ignition System PDF Installation Manual


KIT CONTENTS VERIFY THE CONTENTS OF THE SYSTEM. It should contain the following:
1 DIS8-CHEVY Electronic Distributor
2 Four Terminal Coil Packs
8 Spark Plug Wires
8 Spark Plug Wire Terminals
8 Spark Plug Wire Boots
1 Mechanical Parts Bag
1 Electrical Parts Bag
1 Instruction Booklet W/Coil Pack Mounting Template

REMOVE EXISTING COMPONENTS
1. Remove the wire from the ignition coil primary negative (-) terminal.
CAUTION: MAKE SURE THE IGNITION SWITCH IS OFF!! The wire from the ignition switch to the ignition coil primary terminal is NOT fused in many applications. If this wire is allowed to touch vehicle or engine ground, with the ignition switch on, it can cause a direct short on the battery
possibly causing permanent damage to the vehicle wiring and a fire. Cypress Engineering assumes no liability for damage caused from this occurrence or due to any faults in the existing vehicle wiring.
2. Remove the ignition switch wire from the ignition coil primary positive (+) terminal. Make sure this wire does not come into contact with vehicle or engine ground.
3. Disconnect the coil to distributor high voltage wire and remove the ignition coil and mounting hardware.
4. Disconnect all high voltage spark plug wires from the spark plugs. Remove the distributor cap and set it aside.

INSTALL ELECTRONIC DISTRIBUTOR
1. Install the Compu-Tronix electronic distributor. Tighten the clamp just enough so that the distributor can still be turned by hand. Do not fully tighten down the clamp at this time.
SETTING INITIAL TIMING
1. DO NOT CONNECT THE WIRE HARNESS COIL PACK CONNECTORS TO EITHER COIL PACK AT THIS TIME! Connect the short red power lead from the Electronic Distributor to the +12 volt key-on ignition wire. Make sure the connection is solid and completely insulated. 2. Rotate the engine until the timing mark is about 12º BTDC.
3. Turn the ignition switch on. The red LED static timing light on top of the Electronic Distributor, may be ON or OFF.
If the LED is OFF: Slowly rotate the Electronic Distributor clockwise until the LED just turns on. This is the point at which cylinder #1 will fire. Tighten the clamp. If the LED is ON: Slowly rotate the Electronic Distributor counter clockwise until the LED turns off. The Electronic Distributor may need to be rotated up to 120° for the LED to turn off. Then rotate the Electronic Distributor clockwise until the LED just turns on. This is the point at which cylinder #1 will fire. Tighten the clamp.
4. TURN THE IGNITION SWITCH OFF. The timing is now set with 12° initial advance. This will allow for the engine to be started so the timing can be set.
