I need a schematic diagram of the RainBird-Image irrigation controller, shown on below pictures. It suffers from liquid damage. I can’t recognise some components.
I doubt you will find a schematic but it would be great if you could - I have a similar model I'd like to hack.
What are the symptoms? The switch pads are pretty cheap and might need cleanup (especially the elastomeric on the button). Also, I can't tell if the photo has shadows or there is burning on several of the leads in the upper right hand part of the "solder" side of the board.
The one I have appears to use house marked mosfets.
The unit is totally dead. Two triacs vas shorted. The water destroys the lead of the resistors and diodes. I changed them, but nothing. The LED is lighting, that’s all. The u-controller must give power supply between the 9-24 pins. I measured 0V. I tried to trace the tracks on PCB. I found two interrupted vias. I shorted them, but nothing. Where is the voltage coming from? There are two diodes between each other (the 11-12 component counted from the left side of PCB). What are they? There is no text printed on them.
