The bolt is the battery connection, the ground is on a bolt at the back on the chassis above the plug and of course you have the plug.

So my cars been running without the battery connected for about 4 months! groover can you confirm what that pink ish coloured connection is again please?

Will check on the wire colour in a mo but here is a close up of the alternator and batt on the casing, left is 90-93 and right is 94-96

hmmmm still non the wiser lol. see the nut on the left hand side of my picture you can see what's left where the wire was attached. this is my concern , we removed one wire and a plug , as the other was already off. if that was the battery wire how on earth was my battery lasting so long? my zed is 89

The wiring diagram shows: white and white/red in the plug, white/red goes to pin 6 on the fuse block and seperate white to battery and to pin 2 on the fuse block and black is earth, so it looks like the white (gone pink) wire is probably attached to the battery as its obviously charging and giving no issue, the other white wire goes to the fuse in the box next to the master cylinder, so it looks like the two white wires which are supposed to be attached to the batt bolt one has come loose.

It seems that all the white wires end up at the fuse, so you may not have noticed any difference with the loss of one of them.

Thats definitely the battery wire, did it shear off during removal or been like it for a while? The empty bolt hole to the right is for the earth, even if a few strands were still attached it would of still charged the battery to a point.

It looks like its been off for a very long time!

Would have a trickle charge through the other wires no doubt, but if you were having electrical issues than that would have been the cause

Thanks for your help mate! ill get on it tomorrow ;)

No worries, hope you get it sorted

You will find the wire in the loom and wont go directly to the battery but via the fuseable link fuse box

Sometimes on alternators, if u pull that wire off it can over charge, I've had an alternator charge near 17volts, on a nissan navara cause the fuse on the smaller wire had blown,

 

But with that wire not connected, should have a battery light showing...
