Re: 51 Chev on a S10 frame, named Dale

I have worked with steppers before and it did not work to reverse the polarity of one or both sets of coils on the steppers, they only swung when connected the same as original, so I am guessing the firmware knows they are inverted (self test when plugged in, full sweep) and does not operate. mine were the 98+ s10 variety with an IP that reports back to the BCM/PCM, so older ones may work.

my opinion is, when it comes to modern gauges, it makes more sense that the gauge natural state is in the middle. so high or low readings will catch my eye anyway.
