Here I will show you what parts are fitted in side and out side of you Honda distributor; I will show you how to test your unit and how to repair it.
Before all we need to know what the distributor does, an engine needs to have a spark to ignite the fuel to push the pistons down which in turn, moves the crankshaft around which is attach to the gearbox which in turn is attached to the wheels. The Distributor produces the spark by amplifying an electric current, from 12volts to 30,000 - 40,000 volts, this spark only last for a fraction of a second, so has to be fired at the precise time, this is called timing the ignition, and the timing is set from a point called top dead centre (TDC) |

This diagram shows how a piston works
As you can see the spark is ignited when the piston reaches the top (TDC)
As the engine goes faster the fuel has to be ignited earlier this is called advancing the timing this is controlled by an ECU or on earlier Honda cars fitted with a carburettor a vacuum advance unit on the side of the distributor.
The Ecu knows the speed of the engine by getting a electric pulse from the magnetic pick up sensors inside the distributor. These magnetic sensors are triggered when the shaft is being turned by the engine. |
