As long as the delivery wire from the Alt to the Batt is suitable, you should not have any problem.
If it is three wire ( Ford style ) it will be more stable with a 75 Ohm Excite resistor than the 180 Ohm Excite resistor.
Just my opinion.
Rick, if you need a 125 link, let me know, I think I still have some. And, the volt meter should be fine at the terminal block. If you wish, you can just remove the shunt and Amp meter.
