(one actually failed) We created a shunt to parallel the ammeter which reduces the visible reading to approximately half the actual charge current. They are working well.
So, what does your shunt consist of? I tried putting a 22 gauge wire across the back of the 30 amp ammeter and it pretty much zeroed out any readings on the ammeter.
