Alternator? with a VR and ammeter? UHG! An internally regulated Alternator puts out 4X the amps at 1/2 the RPM's and gets RID of the voltage regulator. If you are going to do a Alternator, get an internally regulated.
If you are using the ammeter and you think it does not work properly, then you are asking for trouble. If just the meter movement is burnt out you should be OK. Most of the amperage goes thru the shunt (a built-in bypass)...... so you are using the ammeter as a junction block. The voltmeter just needs one wire to it and a ground. All wires, big and small, need to go thru an ammeter. Better to leave it unwired (for looks) and let everything come thru a new fuse panel or fusible link.
Do you have a ballast resistor wired in?
