EP-22 Installation Instructions

General Information

The Indian  Electronic Ignition is a precisely engineered solid state breakerless ignition system. Permanent magnets are mounted in a sleeve that fits over the distributor point camshaft.  As the sleeve rotates, these magnets trigger an electronic chip (Hall Cell) which is embedded in the switching module.  The entire Module system is immune to dirt, oil, heat, and moisture.  Firing down to zero RPM it switches twice the energy of conventional systems. Installation is fast and simple.  The Module requires no "black boxes" or complicated wiring, and can be installed in the time required to change a set of points.
In the unlikely event that the Module fails, you can reinstall the old point system in minutes.

Important Information

(please read before installing your Electronic Ignition)

  • The Module is designed to be a bolt on part.  If the Module does not fit properly. or if the magnet sleeve appears to be loose on the distributor shaft, please call 281 360 8657 before proceeding with the installation.
  • The Module is compatible with any "Point Type" after-market or OEM coil regardless of coil voltage.
  • For 6 Volt systems use a coil with a minimum of 1.5 OHMS resistance across the "+" and "-" of the coil.  These usually DO NOT HAVE an internal resistor.  NAPA:  IC10, IC10SB, IC12 or IC12SB.
  • For 12 Volt systems use a coil with a minimum of 3.0 OHMS resistance across the "+" and "-" of the coil.  These usually HAVE an internal resistor.  NAPA:  IC14 or IC14SB.
  • Caution:  NEVER  use an "HEI" type coil with the Module.  This type of coil will provide too much current to the Module, causing it to eventually "burn out" and fail, which will void your warranty.
  • Many times engine problems are caused by poor electrical grounds.
  • Before starting up your new Electronic Ignition, use a digital VOM (Volt/Ohm Meter) to do the following checks:
    • Measure the resistance in the test leads. With the meter set to Ohms, touch the leads together for 10 seconds and note the resistance reading (remember this number).  This reading should be between O (zero) and 0.1 Ohms.
    • Touch or connect one lead to the negative battery post and touch the other lead to the  generator body; read the resistance (in Ohms) and subtract the test lead resistance (determined in  the previous step).  If the resistance is greater than 0.2 Ohm, there is a grounding problem.  Find  it and fix it.
    • Repeat the "ground test" on the voltage regulator  (check resistance between battery (-) and  voltage regulator body)
    • After installing the Electronic Ignition, repeat the "ground test" on the electronic module plate (check resistance between battery(-) and the aluminum base plate on the Electronic Ignition module mounted in the distributor).  Wiggle the distributor to make sure there is a good ground.

INDIAN ELECTRONIC IGNITION

INSTALLATION INSTRUCTIONS

Electronic Ignitions are available for 2 and 4 cylinder Indians.  The same ignition module will work on both 6 and 12 volt systems.
  1. Disconnect battery or make sure ignition switch is off.
  2. Remove distributor cap from distributor.  Leave the spark plug wires connected to the distributor cap.
  3. Remove rotor.  Examine rotor and replace it if the electrode shows excessive pitting or  burning.
  4. Remove points and condenser from distributor.  Remove the point wire that runs from the distributor to the negative(-) or "dist." post on the coil.
  5. Place the Module plate in the distributor.  Large hole in Module plate slides over brass post.  It will fit only one way.  Fasten it in place with the 6-32 x 5/16 pan head screw provided.
  6. Install the magnet sleeve.  Align the mark on top of the magnet sleeve with the slot in the distributor shaft.  When you feel the magnet sleeve line up with the lobes of the distributor cam, press down.  The magnet sleeve should press on by hand.  Some patience is required to get the sleeve aligned on the cam.  It's a tight fit.  Do Not attempt to tap it on. Push magnet sleeve all of the way on.  Top of magnet sleeve should be flush with bottom of notch in distributor cam.  If the sleeve won't go on, apply a light coat of paint, line up and push down to identify the high spot on the magnet sleeve.  The high spot can be carefully removed with a Dremel tool or an exacto knife. If the sleeve is loose, it's probably due to a worn distributor cam.  Try another distributor cam.
  7. Pull the Module wires through the hole in the distributor housing.  Make sure the grommet locks into the distributor body.  Pull the wire through the grommet so there is no excess wire left inside the distributor.
  8. Make sure the Module wires are not touching the magnet sleeve.  If necessary, adjust the wire length (by pulling wire back through grommet) to insure ample clearance.  Wire should conform to distributor wall.  To be extra safe, installer can use a few dabs of glue to hold the wires against the distributor wall.
  9. Replace rotor and distributor cap , making sure all spark plug wires are securely seated in cap.
  10. Decide on how to route wires to coil.
    1.  On two cylinder engines, you can route wires directly to the coil by feeding them between the front cylinder push rods or around the front push rod. A piece of cloth loom (used to protect throttle cable) can be used to protect wires. (Not supplied).
    2. Wires can also be routed through spark plug wire tube to the ignition panel, with red wire connected to ignition terminal and black wire routed down the left front frame to the coil.
  11. Cut wires to fit and install end connectors.
  12. Be certain to connect the correct Module wire to the proper side of the coil.  The Black lgnitor wire should always be connected to the same side of the coil as the "points" wire.  This  should be the "-" negative side of the coil (sometimes marked Dist.). The Red Igniter wire should be connected to  the "+" positive side of the coil (sometimes marked Batt.) or the ignition terminal at the switch. There should be an existing wire that runs from the ignition terminal at the switch to the "+" positive coil terminal (sometimes marked Batt).
  13. The engine can now be started.  Let the engine run for a few minutes and then set the timing by ear/performance or with a timing light and a clear acrylic sight plug installed in the primary inspection hole.  With the plug removed, the $ timing mark on the flywheel can be located and painted (bright orange works well).  Install acrylic plug thumb tight and put bike on center stand. This facilitates timing the engine with a timing light triggered off of the front cylinder while viewing the $ timing mark thru the acrylic plug.
  14. If you want to remove the electronic ignition system, the magnet sleeve can be removed by inserting a small screwdriver through the hole in the side of the distributor (after the grommet and wires are pulled back thru) and prying from underneath the magnet sleeve.

WARNING:

A POORLY GROUNDED GENERATOR AND/OR VOLTAGE REGULATOR WILL " BURN OUT" YOUR ELECTRONIC IGNITION.
