How to test v2.7 Controller board?


#1

My main tube flooded. I cleaned and dried it. It started up. A couple of days later, it won’t start and there is a little corrosion in the corner around OC1 and R13. I cleaned away the corrosion with a toothbrush. Still won’t start. The batteries are fine and give 11+ volts. The BeagleBone starts when powered separately. The problem seems to be with the controller board. Any ideas on what to do, or should I just order a replacement board? Many thanks.
