Lucas alternator wiring help


Featured Posts

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.

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

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