Hi all
I have a 40W UVC globe for pond sterilization, with an electronic timer built in. After powering up, the button on the front selects either a (one off) 2 hour or 6 hour operation.
I would like to bypass the timer, so the unit comes on and stays on. I know how to short across the actual switch, but do not know what to do to bypass the timer chip. This way I dont have to press the button every day, which is not practical!
Thanks in advance for any help.
Allan

hi perthm,
I have lightened your images, also 'mirrored' the PCB track view so that the track is viewed through the PCB.
Are there any type numbers on the IC's.?

It would help if we knew which wires are the mains supply and which go to the lights, also any numbers on the chip.

Better close up pictures is better.
