Initial experimentation with external shunt ammeter

here's one take-off

I agree whole heartedly. I've followed this recipe and since I don't have a bunch of add on gizmos it has worked so far. Replacing the 50 year old wiring harnesses did a lot to calm my anxiety and finding a local rebuild shop that would actually give me an alternator with a factory output also helped. Just like the value of adding front disc brakes, I'm just looking for a way to reasonably protect these old friends for the long haul.
