I had the controller on the bench running a wheel chair motor successfully. Good, I thought. I will have this back in the subaru and be operational before
night. The details are foggy, sometime near the end of unclipping the wires to the batteries, controller and the motor and then discharging the capacitors by touching the motor wires to B+ and B- on the power board, I thought I saw the
yellow fault light blink on. Oh No, did I drag a live wire across the logic board or
ruin something from discharging the capacitors in that way?
So I hooked up every thing again. The yellow led blinks and the motor is running. Remove power from the logic board and the motor stops.
RTD Explorer shows the v-ref fault lit up at the bottom of the screen. It shows throttle graphing and a ragged blue line near the bottom of the graph
So, I need to know how to determine the problem, the lem or more. There is +5v at J3.
If I remove the LEM from the circuit, and apply 5v power to the LEM, I should measure 2.5v between lem pin 2 (output) and pin 3 (0 volt) and also 2.5 v between lem pin 1 (v ref) and pin 3 (0 volt)? On my lem both measurements are 0v. Bad?
With the lem disconected and power off, at control board J3, there is very low resistance between sgnd and out and open between sgnd and v ref. Is this proper?
Will I need to order more than a new lem? I think etlaare had similar problems. Thanks
