Recently purchased ZX40ST that will move forward at about 1mph unless there is an incline which brings it to almost a complete stop unless the grade is to steep which will keep it from moving forward at all. It seems to perform only slightly better in reverse.
I have power at top of the controller: 13.7vdc B+/-, ~68vdc B+/- (havent charged since I brought home last week), ~30vdc B-/U,V,W. Haven't tested at motor poles.
I do not hear a contactor when I press throttle down, should it be audible when first pressing on pedal? Vehicle moves barely, almost not at all, which tells me I have an issue somewhere in the control, tps, contactor, ac motor or perhaps Regen circuit.
I'm learning as I go. All systems seem to be untampered with and it has just under 3k miles. Looks like the batteries where replaced mid 2012 and seem to be holding up to at least get this thing operating at normal speed.
First thought is bad coil in contact or perhaps bad contact armature.
