Thanks for the swift reply pal.
I've connected it right this time and the button on the recoil PCB works.
T to Trigger(
PIN1)
R to Recoil(
PIN4)
G to Ground(
PIN5)
AUX(PIN2) & P1(PIN3) is un-used
Still, when I connect the power supply I get the solenoid to constant ON...!
Measured T - G = 5V, S1 - S2 = 24
I can't see what I've done wrong here. Maybe some conponent is faulty, MOSFET or something?
Any help/pointer much appreciated
Regards
