My old car suffered the same problems, was the crank sensor.

Think iv found the problem

This is a picture of the starter motor wires:



Will i be able to just solder it back or will i require a new connector.
If the latter what sensor is this?

Thanks

Seems that wire actually runs to the alternator?

So although its damaged doesn't look like fixing that will solve my starter problem
Will get this wire sorted today though.

Checked all the wiring to the starter. No problems there

If its the crank sensor would it cause the starter to turn slowly then stop?

If its not turning over its not a sensor, as the starter has no electronics. You just send current to it. What happens is that the starter soaks up heat and the internal bits expand, which can cause it to be tight turning.

If it was turning over but not firing, then I would think crank sensor.

First thing i'd do is take the starter off, clean and re-grease it.

Ok will give that a try now

Ok
After more investigation

Does seem to be a voltage issue.

When driving battery voltage is at 13v.
And when cranking it goes down to 9v.

So going to change out the battery as it was getting old.

I have a bmw x5 diesel battery in, If i get the same again but brand new will it cause any other issue, Or will the alternator need to be swapped for a 180a?

Turns out the ground cable wasnt connected
