Yes. Indeed, just run a wire straight from the alternator output to the battery +, at least for a SB where you can run across the timing cover. In a slant, might be better to run to the starter relay since there is already a big wire to BATT+ from there. If you want to be really clever, look up my post on using a series diode pair that lets your ammeter work at low current and shunts it to battery as it reaches 30 A. I need to do that in my slant and BB too.
