Have anyone tested out this AMP on TACH mode to see what happens? Roland
I have a TransWarp 9 motor (9" diameter, same length as 8" motor) with a Z1K, using AMPS on TACH. I've never seen the tachometer read above 0 unless my foot was on the accelerator. Lots of hills here, so plenty of coasting at high motor RPM.
My truck has a Warp 11 with a Z1K also, but I never could get the tach to work. Toyota pickup with electronic speedometer. It might have worked briefly. I've even changed the cluster once or twice...
Maybe your throttle is partially on - not enough to trigger the high pedal warning (won't start the controller), but enough to cause the tach needle to move.
Could it be EMI? My tach wires were pretty sensitive to noise. I had to move them around and add some capacitors to eliminate interference. Still get interference on my amp-hour counter.
Do you have any other stuff hooked to your motor that might be supplying armature/field current? Didn't your EV have some type of "idle" circuit at one point?
