I'm working on my '67 Barracuda wiring and have bypassed most of the charge current through a wire from the alt to the battery, BUT I also fused this leg with a maxi fuse. I also replaced the fusible link going into the bulkhead with a maxi fuse. I will add a volt meter of some sort before the car hits the road. That will likely be a cig lighter replacement that has two USB charge ports and an LED volt meter.
