MAD ELECTRICAL?

I really used to like ammeters, but the fact is that NObody that I'm aware of, had (back in the day) come out with a decent system that wasn't somewhat or a lotta'what "numb." Some of the Fords you could turn the headlights on/ off and you'd look at the ammeter and there would be a huge question "did it move?"

I'm speakin of the later "external shunt systems. These actually USED the voltage drop present in the factory harness to send readings to a sensitive meter
