74 124 spider alternator wiring.

I am restoring a 124 spider and have the joy of working on the electrical systems and wiring (with a Haynes wiring diagram, one supposedly for this year and model, and one for a 1978 spider). I am not getting charging from the alternator and am not sure if it is a wiring hookup problem or an alternator problem (diagrams are not real clear on this). My car has an electric fuel pump (appears factory) and neither diagram shows wiring for an electric fuel pump. I will have to rewire the fuel pump, but that is not a problem - I can splice into a good switched source.

This is my first contact with FIAT Forum. I look forward to hearing from you guys. Thanks in advance.

Have you checked the feed into the Alternator and feed out? Also, you may have a seperate regulator on that Alternator. you can buy the later built in regulator type and fit that.
