Lucas alternator wiring help

[Canal321]

Hi all,

 

I was hoping someone would be able to identify the wiring connection on the back of my alternator. It's been on my engine for a few years, but never had a belt or wiring, so I'm going to see if I can get it going.  

 

There are no markings next to the 2 terminals with spade connectors on them. Would the blue arrow be the B+ , and the red arrow be the D+ ? There was a black wire connected to one of the mounting bolts that went back to battery negative.

I have wired an alternator before but the terminals were all marked up, Any advise appreciated thanks.

I am sure that you are correct.

[Tracy D'arth]

Certainly correct. The mounting of the alternator on the engine would normally be the B- connection.

It’s a school day, so which model is it?

[Tony Brooks]

To me it looks like the last of the ACRs as fitted to certain Austin-Rover cars, but I don't know the actual model. It was sort of stepping stone between the ACRs with the pudding basin plastic end cover and the A127.

Just to update this, new belt arrived today so I put that on. Wired it as suggested and all works well. Thanks again.

Thanks for telling us, pleased it is working.

Thank you for the feedback - you'd be amazed how many don't give it...
