Might this help explain what is going on?


Had a look a the wiring diagram on GoMog and I have none of those relays - completely different system unfortunately.

I'm thinking that the GoMog wiring diagram is actually wrong. From what I'm reading, an ammeter needs to sit between the output wire of the alternator and the battery.

I've looked at an earlier wiring diagram for a dynamo car, and the Brown/White goes from the dynamo, to the Ammeter, and then a Brown goes to the battery terminal Starter solenoid. That mirrors the route my wiring takes (albeit with an Alternator) so seems to suggest that my car wiring is correct.

I think I'll add a couple of extra piggyback wires to and from the Alternator to cope with the increased ampage of the new alternator.
