Even though I have owned this car for a while I classify myself as an softly educated newbie. I did not drive this car over the winter and broke it out of slumber this spring. However I'm unsuccessful as the car will not move.
It has a 144v pack (18 x 8v), with a DC Power systems Controller (TREX-600?). Much to my dismay it appears this company has long ago ceased to exist. Since I did not do the wiring on this vehicle I'm a little at a loss trying to figure it out, but I understand many of the concepts of how it operates.
The basic problem: The car does not move.
It appears both contactors (negative and positive) respond to the "ignition" key and close supplying the controller with current. However the controller then appears to cycle through on/off supplying the motor with current momentarily, then opening the circuit, then closing the circuit, then opening, etc, etc, etc.
I have uploaded a short video of my problem on Youtube:
The video shows the output of the controller in volts DC. Currently the battery pack is low, about 130v or so. You can see the meter rise to 130v or so then instantly start falling. You can also hear a click of some sort of transformer / contactor apparently internal to the controller.
Is anyone familiar with this controller? Does anyone have trouble shooting suggestions for me to pinpoint / confirm the problem as the controller or trouble shooting to determine if the controller is fixable? I would be willing to attempt myself.
I can't find any reference to this controller on the forum here.
