I started looking at something like that but now I'm looking at a self latching relay on starter press that starts an electronic delay on make timer relay. - just two components. The timer relay can handle 30 amps and can be adjusted from 0.1 to 10 seconds. Just have to find an Australian supplier
You'll hardly need 30 amps as what you are timing here is the coil (ignition) circuit. The starter circuit only becomes high amperage b/w the starter solenoid and the starter motor.
You will have a problem timing it because when switching your ignition switch to the "on" position your coil +12v goes live. Then switching to the cranking position the coil circuit remains unchanged (at +12v) and the starter circuit goes live. So if you hook up the timer to the coil circuit the best you'll get is a delay from the time you switch the ignition on not from the time you start cranking.
Connecting the timer to the cranking position on the ignition switch won't do you any good either as as soon as you stop cranking up the engine the coil circuit will go off.
Connecting the timer to both the "on" position (where the coil would have normaly been fed from) and the cranking position (where the starter solenoid is activated from) wont work either as say you switch the ignition switch to the on positon and let the fuel pump build up some pressure for a few seconds and then crank up the engine - your timer would have started counting when you switched to "on" and then when switching to "cranking" changes nothing as it is still fed by the original connection for the coil (which remains live when cranking).
Am I making any sense at all? Basicaly it will be a rather complicated task to make the timer work I reckon.
) will allow the engine to start.
