So I will stick with 60 amp , run a bigger gauge wire from alt to battery , swith to electronic ignition with the better regulator . What is the trick to bypassing the ammeter , or with the heavy gauge wire alt to bat not required ?
Run 8 or 10 gauge wire...and always us a fusible link that's 4 sizes different (12 or 14 accordingly) and put the link on the starter relay side. I bought a link w/ an eye-let on one side and hooked that to the starter relay stud, then spliced my wire to the other end of it and ran that to the alt. stud. Elec. tapped it into my existing harness and it looks good, hard to tell it's there unless you look close. I then hooked up my aftermarket voltmeter.
or...if you want a true factory look
You can drill out your bulkhead connector, do away w/ the Sta-Con connectors and replace the existing wire w/ new heavier gauge wire (if your running a bigger alt) and run it directly through the firewall (Chrysler did this on later on trucks, fleet vehicles etc w/ higher amp alt's because they knew the firewall connector was troublesome) and up to your gauge. You could then have your OEM style amp gauge converted to a voltmeter by one of the many gauge refinishing companies out there now and then you have an factory wired and factory looking gauge again but without the trouble prone connectors and amp gauge...
