Bosch Hall Effect Ignition on a V8 Engine. The Controller has alloy fins and a Power Transistor mounted in its centre. The Rotor Button has a Reluctor attached to its lower part. Photo by Energy4anarchy. Click to enlargen.

Hall Effect Ignition Triggering:

Traditional Breaker Point Ignitions can be improved by fitting an Hall Effect Kit. This involves removing the Breaker Points and Rotor Button, fitting a rotating Magnet to the Distributor Shaft, and replacing the Points with an Hall Effect Transistor Device. The Rotor Button is refitted as part of reassembly. The Hall Effect Transistor triggers the Coil every time the Magnetic field of the rotating Magnet passes it. 


1. There are no Breaker Points to burn, pit or have their Rubbing Block or Pivot wear out.

2. Transistor switching is faster than Points Switching, meaning the Coil produces more Voltage.

3. It's easy to make these Devices Dwell extend resulting in even further Coil output Voltage than simple Transistor Switching.

4. These are a good option for Starfire and Grey Motor Holdens because Bosch HEI was never available for them.

Bosch HEI:

For red/blue/black Holden 6's and V8's, Bosch HEI is a better option because it provides even better advantages than those listed above. Some of those advantages are a much stronger Spark because the Coil has a higher output and dynamic Dwell which optimises the Coil output by increasing the Dwell proportionately with RPM to mainain high Spark Voltage.
