Charge Locking Pin
So i've been trying to find a solution for this for a while. I'm using a type 2 connector and a two wire solenoid type locking pin that needs a brief +12v and Ground to drive it in and the polarity reversed to remove.
For the firing of the pin, I did have a pair of changeover relays which were activated when a ground signal was received from the Charge controller but I didn't realise at the time that it only needed a short burst of energy and have burnt my first solenoid out.
So I need an alternative, I did consider adding a timer relay in but I've not worked out a way to get it to function when the ground is removed and to retract the pin.
Can anyone help with a solution..............please?
