Installation with ballast resistor (or wire)

- Remove the points and the condenser and its wire from vehicle.  - Place the magnetring on the rotor shaft.
- Smear a little bit of the white paste on the bottom of the E-Spark plate.
- Place the E-Spark kit in the distributor where the breaker point used to be.
- Make sure that the ignition wires have enough slack and are not rubbing on moving parts.
- Warning: Reversing the red and black ignition wires will destroy the ignition module and void the warranty. 
- Connect the E-Spark module’s red wire to positive connection BEFORE the ballast resistor (Power during start and ignition). 
- Connect the E-Spark module’s black wire to negative ( - or 1 on Bosch coils). 
- Start the engine (one might need to rotate the distributor somewhat before starting). 
- Set the ignition timing using a stroboscopic timing light.

Installation Positive earth

- Remove the points and the condenser and its wire from vehicle.  - Place the magnetring on the rotor shaft.
- Smear a little bit of the white paste on the bottom of the E-Spark plate.
- Place the E-Spark kit in the distributor where the breaker point used to be.
- Make sure that the ignition wires have enough slack and are not rubbing on moving parts.
- Warning: Reversing the white and black ignition wires will destroy the ignition module and void the warranty. 
- Remove the wire on the - connector from the coil (originating from the ignition switch).
- Connect the E-Spark module’s white wire to the wire just removed (originating from the ignition switch).
- Connect the E-Spark module’s black wire to negative connection on coil.
- Connect the wire that original was connected to the breaker points to the chassis or + of the battery. 
- Start the engine (one might need to rotate the distributor somewhat before starting). 
- Set the ignition timing using a stroboscopic timing light.

Determing coil resistance

- Use a common digital multimeter in the 200 Ohm mode, cross the two leads of the multimeter.
- Allow a few seconds for the reading to stabilize and write down the reading. This is the multimeter's inherent resistance.
- Next, still in the 200 Ohm mode, measure between coil’s + and - terminals (all other wires disconnected).
- Allow again a few seconds for the reading to stabilize.
- Subtract the first reading (multimeter's inherent resistance) of the current displayed value.
- The answer is your coils resistance.
