Re: LED Issue- PMW to Sidecar

The LEDs next to the relay port you are using on the sidecar should light up when triggered from your code. Is this occurring? If so you should focus your troubleshooting efforts on the spike. Is it powered and the PWM firmly seated in the housing? If so, your spike may be the problem.

If the LED on the sidecar does not light up, please verify that the sidecar is powered with 12V from the power distribution board. You may also want to investigate the possibility of a bad sidecar. We have had sections of this go dark before (usually as a result of poor metal shaving control). Do you have a second (working) sidecar you can swap in and try?

If none of these prompts led to a solution, could you post a couple pictures of your wiring. That way everyone can verify your connections. Good Luck.
