2005 GT gauges shows random

[shywaz]

Replaced all 6 stepper motors, what are the odds i got new but broken ones?

Tacho seems ok,
Checked speedo with gps, readings are accurate - but when i stop needle doesnt rest on zero, it still shows like 10mph.
Fuel seems ok.
Coolant temp is 2/3 of full - is this normal or my car is slightly overheating?
Amp meter and oil temp - seems to be ok, but rest way way below zero. (Somewhere around 10 oclock)

What i might did wrong?
Double checked soldering places, all joints seems to be ok

I'm sorry to hear you are having problems. I can't imagine that ALL the step motors went bad at the same time. That's absolutely silly. But, it seems you did fix some problems. You may have something else going on. Possibly grounding. And probably something else, as well.
Of course, I could be wrong.

OBDII readers are cheap (I went with the Veepeak on Amazon for $20) and the Torque app is $5. Wealth of info is available, with just that...

Finally i have it sorted! It seems to be related to my constant brake lights on, which was caused by burned microcontrollers on SJB. Replaced two of them, all problems are gone.
