I removed my alternator to replace the water pump housing and unfortunately dropped it. It was pretty banged up but also pretty old so I thought I'd buy a new one. I purchased the suggested Lucas 17ACR from Rimmer Bros (see pic). The wiring connections are very different from my old one (again, see pics). The new one has 3 connections and my old one has 5. My old alternator (probably not original?) was labeled ACR 15, 16 AND 17. I assumed (perhaps wrongly) that a 17ACR would work. Do I need some kind of adapter? I've never worked on alternators before so I'm bit of a novice. Any help/advice would be appreciated. Thanks!

Yeah, there is a wiring adapter, or you can cobble up your own. This document should be on the Moss web site somewhere, but they've "improved" it until it won't work with my browser setup.

I went to a Delco Atlernator. I could not keep Lucas alternators in my car. I went to a 75 amp Delco and used the Moss Motors adaptor and instructions and not had any problems. Very easy to do. Maybe with Electronic fuel injection, Halogen headlamps and stereo I kept burning them out.

I actually got an alternator from AutoZone that had an original application in 78-80 Ford Fiesta's. It's a Bosch and it puts out 65 amps. Best part is, it's a direct bolt in, and plug in with the plug on my 74. Works great. Part number is 13107N, this is for the Bosch equipped ones.

Thanks,
Perry
