I'm fitting a new uprated alternator and am a bit confused with the wiring in my car!

This is the wiring diagram (from GOMOG). I have a two wire alterantor. There should be a large gauge brown wire that goes to a post on the starter solenoid, and from there another brown wire goes to the ammeter. I have that Brown wire that goes to the Ammeter. The back of my Ammeter has two Brown Wires and two Brown/White wires as per the diagram.



However on mine I have a Brown/White wire that goes from the alternator into car. It then somehow has connectivity with the two Brown/White wires connected to the ammeter but I think the two brown/white wires on the back of the ammeter are a smaller guage. When the thick Brown/White wire is disconnected from the ammeter, the lights and ignition still work fine. When I turn the ignition on, there is 12V at the 'alterator' end of the thicker Brown/White wire.



The current wiring works (as in everything runs and the battery charges OK) although I never get much movement from the ammeter.needle.

I'm thinking that I just create a new brown wire from the Alternator to the starter solenoid post and then cap off the previous Brown/White.

Any thoughts?
