Hi Jimmy thanks for the input,
Regarding the switch, the intent was to try and simplify things by having the one side of the switch not through the relay. That way regardless of whether the relay is on or not, as long as there is the 24v feed to the solenoids then Solenoid #1 will always function ( as its the more crucial one).
Solenoid #1 performs it's intended function completely fine at the moment. Is there no possible way to modify my Arduino sketch for what i require for Solenoid #2 with just the one input pin as it is currently?
Kind regards,
Daz
