Dave will be able to get it okay, I’d look it up for you but I don’t have IE on this machine and, annoyingly, AGORA will only accept a connection from IE. 😕
Had a couple of these that….fire up as you lower the pcb assembly from the roof.
Undo the screw and lower the front end of the light/pcb unit with power on, if it fires up there’s a broken wire/connector somewhere, not a £70.00 pcb.
