I have gone as far as swapping the cables on the side of the panel to see if indeed the left motor has shorted,found that the left motor will turn if run off the right transistor.I have replaced the driver board and steer angle board(which was faulty).At power up the top lead of the transistors reads 0vdc,when a direction is selected the left transistor reads 2.39vdc while the right reads 0vdc.as you accelerate then the voltage on both terminals climbs to battery voltage then goes into 1a>Im at a loss as to where this 2vdc is coming from and its obviously not letting the transistor work correctly.Any help would be greatly appreciated.
