I'm having a problem getting my engine to keep on running when I disengage the starter motor. When I turn the key and the starter starts, the engine runs but as soon as I let go it stops
I know there is 12v going to the coil when the starter is engaged (because theres a feed from the solenoid) and there is another feed though a 'resisting' wire, what should the voltage be through this wire?
Any idea's?

Does it run well when the starter is engaged or does it sound like the starter is all that keeps it going? You probably know about the ballast stuff to keep coil voltage similar during starting, if the engine does run well then i guess its something to do with this. Maybe something wrong with the 9v supply when the starter isnt engaged? Just guess work anyway, you almost certainly know more about engines then me anyway!

just reread your question and thats actually what you asked, i think it is 9v when the starter isnt cranking. all hearsay though...

yo lee there should be 9v to the coil with key in run position,you got the right coil?should say resisted on it

I have had the engine running The only way I can get it to run is to pull the black/yellow wire (photo) from the solenoid as I disengage the starter.



It seems to be earthing through the solenoid as when I have the ignition on, there is 0v to the coil but it I pull the black/yellow wire (photo) from the solenoid, the voltage at the coil is 10v.

I bought the solenoid from HERE Reference CLS102 is the one I bought, I wonder if I should have bought Reference CLS103 as it has an extra terminal to supply the full 12v momentarily to ballast resistor ignition systems.

All suggestions gratefully received

yup you got wrong solenoid,ign juice is going to starter brushes then earth

The black and yellow wire goes to the same terminal as the black and red one is what he means Lee. Piggy back it on and it should work.

yours, Pete.

What you mean is I need to get one of those piggy back spade connectors to connect it to the ignition 'key' (black/red wire) ... or just crimp both wires into one?

Either will work....
