Hey guys I have a 83 city and am swapping the engine out for an MG metro lump. Is there a wiring diagram for swapping the solenoid from the one of the wing to the one on the starter motor as we and Rusty doing it this even but seem to have some issues getting it to work.

 

Cheers.

You have pictures don't you? Use them!

Sure Rusty can explain whats going on better

[rusty789]

Anyone?

 

What wires need to go to the starter motor?

 

The wing mounted solenoid is working, but I think the starter also needs an exciter 12v feed as well? If so which connector does it need to go to?

Can't see why you need (2) solenoids when you are using a pre engaged starter why ?? and is that starter the right one for the flywheel they have different ring gears for inertia starters and pre engaged starters they work different way rounds.

I thought there was a red & white wire to the small terminal on the starter that comes from the ignition and in the picture you are bridging the wrong terminals.
With ignition on you should have feed to starter then you bridge the small terminal with the main cable.

The pre-engaged as its own solenoid fitted, the wing fitted is for an inertia one.

Leaky bought the right wiring loom for the car, but not the right loom for the engine, hence the loom going to the solenoid on the wing... I'm trying to get it working the tidiest way for him. As far as I'm aware it's the correct starter for the flywheel/engine (It's not my car...) but it is turning over now, just not firing, but fueling and other wiring may be the issue.

I tried that, that's what the red wire is doing, turns out you need to bridge the main incoming and larger spade for it to turn over... So really the wing mounted solenoid is still doing all the work.

 

The pre-engaged as its own solenoid fitted, the wing fitted is for an inertia one.

 

Correct, we know that, I was asking about how to wire the starter motor to the solenoid and what connections need to be made.

Where's the power from the battery going?

Steve... I like the "tip of the month".

 

+1 for Steve's pictures.  They show what I would do.

 

The deal is that wiring for the wing mounted solenoid does not include the starter relay found on later engines with the pre-engaged starter.  The pre-engaged starter solenoid draws a bit too much current to be powered directly from the ignition switch... hence the starter relay.

 

Lacking the starter relay, wire up the wing solenoid as "normal".  Take the large cable that used to go to the inertia starter and run it to the threaded post on the pre-engaged starter.  Make the little (red) jumper wire shown in Steve's pictures that goes between the small spade lug on the pre-engaged starter and the threaded post terminal there.  What this does is use the wing mounted solenoid as a starter relay and a main solenoid.  When you turn the key, current travels from the wing solenoid to the pre-engaged solenoid.  The jumper wire makes sure that the pre-engaged solenoid is powered so the new type starter will work.  It's easy and clean.

Lol, you're welcome!

Oddly I got those photos from a few threads on this forum by searching 'solenoid wiring'.

That's pretty much how I have it wired but looping to the bigger spade, it seems to be working, if I should be using the smaller spade what is the bigger one for?

[rusty789]

At current, it's wired like this, going to the big spade, but it should be going to the smaller one?

 

EDIT: It is turning over like this.

This is great....:)

So I am struggling with this as well. I bought the wrong loom with no starter relay provision....and of course I have a pre engaged starter with solenoid attached.....

Can I wire up a relay to simply take the place of the solenoid that would be mounted on wing....? As shown in Steve's tip of the month?
