I have seen a few posts about this but I wondered if anyone could help me in particular as all of the descriptions of coloured wires to move don't match up with my loom as it was obviously messed around with by the previous owner causing me no end of headaches so far....

I need to wire in a pre engaged starter after swapping the engine of my 1983 mini to a 1994 engine after a big end failure... The image blow shows my starter solenoid, what do I have to move to where to get the car to fire up, keeping my solenoid as most suggest.

Thanks Rob

Just done this myself,

Put the large dia red wire on the same side as the one from the battery.

Put the other end of your red wire on the bolt type connector furthest forward on the new selanoid.

The small signal wire at the top of you picture (the one that flicks to 12v when you crank from the key)
Extend that so it goes to the large spade concector on the new selanoid.

Job done :)

Not really, the power required for the solenoid on pre-engaged is substantially higher - higher power = higher current.

 

What you can do is to either add a relay powered from the original start cable and fused off of the battery feed before heading off to the new starter or leave the old solenoid in place, join the two heavy cables together, take a fused supply off the spare big terminal straight down to the new starter.

 

The inrush may not be good for your ignition switch if you don't.

This as above.

Ok... Got it working the way I did this was to put the large red wire from the solenoid picture above onto the same side as the rest therefor bypassing the solenoid and attach the other end to nut terminal on the starter motor.

I then took the switched ignition live off, which is the only one not directly attached to the terminal, it was the wire in the middle of the two nut terminals kind of on its own, mine was a red and white wire and attaching it to the large spade on the starter motor.

I took the advice of moving the large spade which was wrong as the large spade was the power to my horn and lights. I found the right wire by using a light probe which lit up for all the cables bar the red and white which glowed when I switched the ignition on. Once I connected the red and white wire to the large spade on the starter it turned over perfectly!!

Thanks for all the input guys!!

You got it working but you may well knacker your ignition switch. As above, the inrush and hold in current is quite high.
