i don't think I have ever seen a volt gauge in any factory vehicle. Why do you guys want to
remove the ammeter? Just make sure your connections are clean and tight. If you're worried the by-pass will cut the current through the bulkhead and ammeter more than half.
I ran a 10 ga with a maxi fuse near each end from my alternator to the starter terminal. I left the original wiring. The ammeter stays close to center with very little movement to charge and discharge. I hung a volt meter under the dash to keep track of the charging system.
