For both of my 1966 Mustangs I noticed that when the ignition is off, all of the gauge needles "zero out" except for the ammeter. That needle stays vertical in the center of the gauge. The others move to the left or the lowest reading on the scale, so 0 MPH for the speedometer, E for the fuel gauge, etc. Is this normal, or are both of my gauge suspect? I would assume that zeroing out all of the gauges would be a simple owner verification that the gauges do work. Each time the car is started, the gauges move from the rest position to an operating position. I went on the internet to look at photos of 1966 Mustangs for the quick couple I looked at, it was the same thing. All gauges except for ammeter that zeroed out at rest. Also, neither of my ammeters move very much. I can put a full load on the electrical system with lights on, heater on, radio on and I can't see that the needle moves at all. I would appreciate any input from the electronics experts and just observations from the members on their gauges. Thanks.
