Default Lazy gauges, why???

Just checking why the aux gauges in my Series III are slow/low. Mainly the fuel tank level and ammeter. Fuel tank gauge is slow to swing around and seems to read a little low when the tank is full and the ammeter is very slow and reads under 13V even though I can check the battery and I have well over 13, if not 14V.

Just curious. Car is running great so it's not slowing me down, but if there is something I can do to remedy the situation that would be nice too.

i would guess a kinked wire or defective ground wire...i've seen all sorts of issues with mine...i even had issues with my leaking windshield letting water in that would short the dash gauge lights...

The gauges could be perfectly dry and and good working order and still be lazy. Frankly, I've never seen/driven a Ser III that didn't have lazy meters to one degree or another.

You can go thru cleaning connections, checking wires, etc etc....maybe you'll find something but I wouldn't get my hopes up
