TIM-6 (6 volt) Electronic Ignition Module
These ignition modules are designed to work with small model or hobby engines. You build it yourself from a kit!
These ignition modules are used on all J.E. Howell IC (internal combustion) engines, and may be used on most any other single or multi cylinder engines if using with model ignition coils such as the Exciter, Modelectric or Gettig and having a primary winding resistance of not less than 1 ohm.
This ignition module is triggered with a Hall effect device and magnet (included). The small magnet is attached to the cam gear, and when the magnet passes by the Hall sensor, a signal is sent to the ignition module, which amplifies the signal and sends voltage to the coil. When the Hall sensor no longer "sees" the magnet, the signal stops, which stops coil voltage, thus causing a collapsing magnetic field in the coil secondary winding to generate the spark plug spark.
To run an engine with electronic ignition you will need: TIM-6 module, a suitable 6 volt ignition coil, spark plug and a good 6 volt battery that can supply at least 4 amps.
If you want to use automobile or motorcycle ignition coils with a primary winding resistance less than 1 ohm, use a proper ballast resistor in series with the coil so the current draw is not over 4.5 amps.
For use with 6 volt batteries (or 4.8 minimum to 7 volts maximum) on most any engine type.
Kit contains: (1) TIP42C Transistor, (1) 2N2907A Transistor, (4) Resistors, (1) LED Timing Light, (1) 3 Amp. 40 volt reverse polarity protection diode, (1) Hall Effect Magnetic Sensor, (1) Length of Heat small plastic tubing to insulate the Hall Sensor leads, (1) Rare Earth Magnet, (1) Drilled Printed Circuit Board, Circuit Diagrams and Construction Notes. Also includes a PCB Screw Type Terminal Strip for ease of connecting or removing your battery, coil, and other wires.
Note: Due to component changes, some PCB holes WILL need to be drilled slightly larger.
The circuit board is approximately 1.35" wide by 1.70" long. Just to the left of the circuit board is the Hall Effect sensor and the dot just above it is the rare earth magnet which is just 1/8" in diameter and 1/16" thick (3.2mm x 1.6mm).
The Emgo Universal ATV Coil, #24-71532 works well with this ignition module.
