Yes, thanks for the help Ray. Unfortunately more is required.

I think I’ve established what’s going on with the red wires. The main battery positive goes to the starter, which is effectively used as a another junction box. A pair of red wires come from the starter +ve and go to the original factory junction box. The pair of red wires from the alternator (the bolt on connection and the double spade type connector) also connect at the starter +ve.

Will this arrangement allow the ammeter to work okay if the b/w wire is just spliced into the the red wire (previous picture with the current crimped butt connector) or do I need to move the pair of red wires that originate at the alternator to connect at the current crimped butt connector near the b/w fuse?

Thanks again.
