I have 3 sabertooth 2x60 boards and all are causing different issues.
Hardware Setup
I have already followed official troubleshoot guide by dimension engineering but no luck.
Board-1:
Channel 1 of the controller board works fine, I have tested with pwm mode aswell simplified serial mode but channel 2 doent work with the same hardware setup as shown here
.
Board-2:
This board shows status light green but no motor motions are observed with same setup as shown for board1.
Board-3:
This board doesn not drive motors and no status light is observed.
Contact Dimension Engineering support for further troubleshooting instructions:

Disconnect all wiring from the Sabertooth. Take each one that you have and set all the DIPs to the ON (up) position, except #4 set to OFF. Apply DC voltage of 7-30V. How do the LEDs behave on each? How does the fan behave on each?
@MYBOTSHOP_Support After disconnecting all the wiring and applying the 12V, I have observed the following behaviours on all three boards.
Board 1
- Status light turns on (green) and stays on.
- Fan spins for 2-3 seconds and then stops

Same behaviour as board 1
Board 3
Shows no response.
- No led lights
- No fan spinning
