I am very sorry to post another solenoid wiring post, But i can not find the answer im looking for.

I have done a auto to manual conversion the wiring in the car is for pre-engaged starter. The engine thats going in is inertia. I have a 4 terminal solenoid. Ballest ignition + coil.

Now i just cant figure out which wires go where? I have all the brown wires on the post with the spade connectors on, And some battery cable on the other post going to the starter.

Now i have a pink/white wire with a female spade connector which i think goes to the coil + side?

Yellow/white wire

Black wire from dizzy ( - side of coil? )

2 x white/black wires 1 with female spade connector and 1 male. (think ones rev counter?)

All the solenoid help topics i've looked at today all say they have a red and white wire but i dont?

Can anyone help me please? Spent hours scratching my head this afternoon.

Thanks

All what you say sounds right.

The white/yellow is the ballast byepass, one end attaches to one of the small spade terminals on the solenoid the other end goes to coil positive.

The solenoid energising wire from the key side is actually white/red

The short wire off the dizzy normally connects to a white/black this runs through the loom and attaches to coil negative

Do you know which spade connector the yellow/white wire goes onto? Is it the one that's directly under the brown cables? which means it would be permanently live? Thanks for your quick reply ;)

[lrostoke]

found this picture the right hand solenoid is yours...you can see the smaller spade I mentioned, the've labelled it yellow..

I've just noticed it says brown/red for the solenoid energiser...my mistake early white/red is wrong....look for a brown/red

neither of the smaller spades should be live , one will be live at the same time as the threaded terminal that connects to the starter is, thats the white/yellow connection..

They should have different size spade terminals...One is really small the other is a standard size.

sorry didnt see that picture.

AHA! so the brown/red wire currently has a large male spade connector that goes on the battery live side at the min, i need to change that for a smaller one! Ill give that ago mate thanks very much.

If you have a ballast coil its the right solenoid.

Is the solenoid earthed....it needs to be screwed/bolted to the bodywork or engine

Yes bolted it to inner wing after a good wire wheeling on the drill. Also got 2 new engine earth straps. Im going in the garage to try this out stand by. lol. Thanks for your help.

Still no good is it possible to blow a solenoid? Its just that i've been playing about with it for ages today trying different wires on different connectors to try and get it sorted.

Do you have a multimeter or can you borrow one?

You can perform a sanity check using the multimeter to check resistance (Ohms) between the mounting bracket of the solenoid and the two small terminals. When you make that measurement, you will find that one small terminal to bracket will have measurable resistance... probably something between 10 and 90 Ohms. The other small terminal will have infinite resistance (no conductivity). The meter will look like the probes are still not touching anything. The brown/red wire goes on the terminal where you measured resistance. The white/yellow goes on the small terminal with infinite resistance

Also keep in mind that the solenoid terminal where you attached the battery cable from the boot is the same terminal that gets all the brown wires. The starter motor (short big cable) goes between the starter motor and the remaining threaded post on the solenoid.

As Steve said, the solenoid MUST have a good earth connection through its mounting bracket.

Ok nothing across spade terminals at all. But i have just had a look at the starter relay. It has 2 brown wires and a red/white going in to it, There is only one live brown wire when the ignition is on or off does that sound right? I think ill give every connector a good clean tomorrow and see what happens.

[lrostoke]

the starter relay should have a brown wire this is perminant live, a black wire which is ground, a white/red which comes from the key, and a brown/red which goes off to the solenoid.

[leigh21]

Yes thats right, But i only have one live wire when the ignition is on or off. Surely the other brown wire should be live with the ignition on?

[lrostoke]

when you turn the key to start position the white/red goes live....this switches the relay and the brown/red goes live

[leigh21]

Ill replace the relay tomorrow as this isn't happening Thanks

[dklawson]

For the record, I did not say to measure across the small terminals of the solenoid. Measure for resistance between the small terminals (individually) and the solenoid mounting bracket. The small terminal with measurable resistance to the bracket is where the brown/red wire would go. The white/yellow would go to the other terminal.

There is another option if you have confirmed that the white/red wire goes "high" when you turn the ignition key to the run position. Again, IF when you turn the key to the start position you find voltage on the white/red wire, you can disconnect that wire from the relay and make an extension for that wire. You run that extended wire to the solenoid directly as was done on early cars with the inertia starter. Of course... you still have to run this wire to the correct solenoid terminal.
