Before we go any further..... you have converted to 12V and now an alternator/voltmeter/ammeter. Did you use a harness kit for all this or what?. Are you done with all the wiring except for the alternator and deciding on voltmeter or ammeter?
I would guess that the alternator 10ga wire would still connect to the + pos volt meter post NO or should it be connected to the starter/battery. YES
"I am OK with continuing using the ammeter but am worried that I may be overloading it. Is there any advantage to running a 50amp fusible link vs a 50amp fuse?"
Fusible links are just a piece of wire with a high temp insulation. The wire inside is meant to be sacrificial and melt to a open circuit. You buy them by wire size. They are sized 4 wire gauges less than the circuit wire they are protecting. So a 10ga gets a 14ga fusible link.
The ammeter, as you know, measures charge and discharge. One terminal of the ammeter gets battery pos and the other ammeter terminal gets all the "load" wires. Which is basically everything.
