So I decide to use an alternator from a b2200 on a rx7 fc 86 the tricky part is when I plug in the connector a relay on the CPU turns on and the idiots/warning light turns on so how can I find a solution for this? Hope all of you can help me!

my first question is why? Is it actually a higher amp alt? And without knowing how the wiring is on a B2200, gonna be tough to help you

Why? I live in El Salvador and it's hard to find things of rx7 and the unique alt that I can use with same amp it's that but it's a reasonable observation what about the wiring ? I search and nobody got the wiring diagram !

Idoit cluster lights up when the alt is no good. So youve probably got a bad one/wiring issue. Maybe terminals are reversed? Did you research this swap or just plug it in?

Look at the Ford Taurus write ups there's diagram in those thread with s4,s5,ford alt conversion

First of all I reverse the terminals and the idiot cluster lights gone normal maybe this would be and second I made a several research and it's the same position for the fc s4 alt harness and at the same time I just plug it in!

By the way here's a pic of the alt or how it looks !!! Obviously I just use the T connector the other one I just research it's for the choke for the b2200

In this forum or outside?

I bought it refurbished so they tested the alt and it's functional maybe the wires position change on the b2200?!

exactly why i'm asking if it's actually charging YOUR car. check it.

if worse comes to worst, there has to be a B-series truck site that has links to a wiring diagram.

as a matter of fact, here:

Kind of like what I was saying earlier...

This is the thread I'm talking about . I see 13.7 or above since the swap . I found stock ford alt connects for clean install . I didn't have to extend my bracket or grind down anything . I think it has to do with the Cosmo serp belt setup I have though so most will have to mod .like the thread says
