Re: Relay Outputs on Digital Side Car Not Working
If the Relay LEDs are still not lighting up, then the code & firmware need to be checked.



This is more for others you may read this later...
If the Relay status LEDs were lighting up (and the Spike still wasn't responding), then I wouldn't suspect code or firmware any longer. Just make sure only the Relay green or only the red come on at a time (assuming that you are using the Spike to control a motor).

I'd next test the Relay output pins with a multi-meter to see if you see power to match the LEDs. 0v on a pin if the corresponding LED is out, 5v if the corresponding LED (red or green) is lit.

If that passes, then work your way towards the Spike.

Plug a PWM cable into the appropriate Relay, then use the multi-meter to test the far end of the PWM cable.

If you get a signal all the way out there, then the Spike is the remaining issue.
Connect it and the Spike LED should show orange when it has 12v power, otherwise the color should match the DSC's Relay LED.
