Ok so i believe i may have solved my issue.

http://www.theminifo...o-well-thenbam/

The thick brown and purple cable from the alternator wasnt going anywhere. i found a similar size cable bolted to the starter motor. should these be connected?. if they are then it was right infront of me the whole time!! im worried a may have spun the connector out when removing the cable on the alternator. does anyone know if this would bugger it?

thanks for your help, fingers crossed this is it!

Sounds like it. Not sure if MPi is the same, but the SPi has 2 thick brown/purple cables providing current from the alternator to the battery via the eye connector on the starter solenoid. These are individually wrapped in heat resistant material inside a black PVC sleeve. I think there are 2 cables as this would be more flexible and still carry the 45 amps.
Hope this fixes it

Since it is an MPI (or was) it is probably missing the fusible link on the brown /purple wire that then connects to a brown wire that attaches to the starter solenoid. See page 15 of the attached PDF.

did some research appently they dont make it anymore and its really hard to get hold of. anything stopping me just having a straight through cable?

Fusible link is there so that in the event of an accident and the wire shorting the fusible link will blow rather than the wiring overheat and cause a possible fire.
Earlier minis and other cars did not have this.
So in theory you good replace it with a normal cable, but you would be undertaking that risk.
Fusible link cables should be available as all modern vehicles have them.
Are you sure yours has failed? Check the continuity across each nd of this cable.
I thought your original post referred to a missing connector, not a blown fuse link?

I only found some on amazon.com (US)

It might be better to use a large in line fuse instead of nothing.

its not failed, there just isnt one.

ok so now the question which one?

One of the amazon descriptions suggest that if you are using a 12 gauge wire to use a 10 gauge link. I believe that alternator output wire gauge has to be at least 12 gauge.

this is all yank tho cant find any uk suppliers. surely i cant b the only one with this

[xrocketengineer]

Well maybe checking with minijosh92 or r1minimagic in the breaking section to see if they have the wire from the alternator to the starter with the link.

Not sure this will help, but this is what they look like.
