Re: HELP NEEDED: Solenoids not firing

I am no expert, but I believe the solenoids are not polarized. The coil is active when there is current and passive (pilot air holds last state) when no current. They even work with AC signals.

My suspicion (as raised by another post) is that the code is sending an activate signal and immediately sending a deactivate which is too fast for the mechanical solenoid to move, causing the dim light and the 200mV measured voltage. I would like to see if they can send a healthier pulse.
