Good evening…. I’m new to this forum and looking for some expert troubleshooting / help
I have a Sabertooth 2x32 driver board.
I am supplying 24VDC to the B+\B- terminals. There is no “status” or “error” LEDs illuminated when power applied and only periodically I will get a 5VDC output on the sabertooth to my AR620 receiver. I’ve disconnected the motor load from CH1 and CH2, attempted to drive the output channels remotely, and independently using the DIP switches on the sabertooth. I never get any output voltage. I’ve removed the cct board from the heat sink to check for corrosion. None found…… troubleshooting guide for this board says possible circuit board issue…… anything else I should be checking before I throw it away??
Many thanks!
