Bulkhead bypass vs ammeter bypass

I go both ways (No not like that...) If using a stock say 38 amp alt and not doing a complete re-wire
I tend to drill thru the bulk head connector(they have lots of empty spaces)then run a 10 gauge thru the hole to the ammeter. Doing anything more amps than a 72 amp then yes by pass the ammeter. We usually send the ammeter out and have it rewired for volts if doing a semi resto making it look stock to the rest of the gauges. My 2 cents.
