'68 Barracuda - charging system questions

all good ideas thnx - yes am getting power to all in car -all works fine. I already have a volt gauge installed so am not concerned with accuracy of ammeter - it has always just barely moved from from dead center - which maybe says it was doing pretty well - examples: 1) with key just switched to 'on', turning on the headlights would move it slightly over to the discharge side. 2) with car running, turning on headlights and wipers would move it a little over toward the charge side. But overall it's function is not a concern to me - just do not want it to be a source of future problems. SO...will check to find poor connections/voltage drops. Part of my issue is not being able to access ammeter - dash removal is not something I want to tackle. Everything electrical on car is working fine BTW. I had the bulkhead connectors apart last year and cleaned up where needed - none looked really bad. Will have another look. Am I not taking the charging load off the ammeter by installing the bypass? (I understand it is still in line and getting power).
