^^That might be but some of those are REALLY numb. One way to find out--do you have a load tester? Get the thing running on high idle and put some load on the battery like maybe 50A and go take a quick look at the ammeter. It obviously should be charging hard.
I once lengthened a piece of wire down by the alternator to "de-numb" a Ferd one. I've forgotten, I think I added 3ft or no10 to the wire?? This provides a bit more voltage drop in the harness and causes the ammeter to read further over DO NOT ASK HOW!!! This was decades ago (in the 80's) and hell I don't remember LOLOL
