The saga continued but is now fixed. After replacing the in-line glass fuse, hook my controller up to the track. When I switched it on, I noticed both LEDs were eliminated, and “PT” was is displayed. Indicating I needed to program the trigger. Since I was at a friends house, I quickly pulled up the manual from the webpage. I went through the steps and reprogrammed the trigger. I had used a 5 V battery plugged into the micro USB port during the reprogramming. Back at the track I hooked up the controller, switched it on, and PT was still displayed at this time I could pull the trigger and the motor in the car would run erratically. So with the controller still hooked up to the track, I switched it off. I held down the three buttons switched the power back on. I released the buttons. I pressed the round brake button, and now the controller worked as it should. I will have to connect the controller to the app and verify the firmware version, and if the break is still set to the Linear mode.
