We have tried multiple scenarios trying to track down the issue and these have included: changing the constructor (new relay(1); new relay(1,1); new relay(1,1,kBoth), we have changed the code and replaced the kReverse, which works, to kForward. We have even verified that kForward has a value of 2 by outputing the value to the dashboard.

When we watch the relay, reverse does turn the LED red but forward never changes to green.

Please post code of your constructor, and code where you command the relay to change direction.

Have you tried swapping out the relay and the results are the same?

Are you running the test with the motor connected or disconnected? I would remove the motor from the relay and just verify voltage output from the relay terminals for now using a volt meter.

Regards,
Kevin
