Yes, it's across the terminals in reverse polarity. That is, the cathode (bar of the diode symbol) is towards positive. When the solenoid is on the diode is not conducting. When the solenoid is turned off its magnetic field collapses, and the induced voltage spike is shorted out by the diode.I have it inline with the solenoid as that seemed to make sense to stop the flow going the wrong way round the circuit. From what you suggest I actually need it to be directly across the terminals, I'll give it a go to put a diode in the screw terminals along with the leads going to the device.
Thankyou.
