Reply to "MTH PS2 Cab Forward Flickering Lights"

I was running it a few minutes ago, and when I pressed the smoke button and turned off the smoke, the headlight, cab light and class lights turned off! Used the LIN key along the bottom of the screen, and the headlight button on the remote and turned them back on. But why would the lights go off? It's happened previously, but it is annoying when it occurs. The tether is a pcb, and it's tight in its socket. I set the voltage at 15 because the lights flicker above 15 volts.
