We had some nice wins today and got pretty much everything working on Craig's Whitewater, apart from a couple of stubborn optos.
Replaced some bad caps, re-flowed solder to all bridge rectifiers and added jumper wires on driver board, as per Nino's excellent guide.
Flash lamps all now flash after replacing three bad TIP102 transistors.
Switch matrix is now also working after replacing CPU chip U20 - ULN2803.
Also the topper chase lights are now working.
Now I've read lots of hype about the Whitewater topper, but I have to say that I was totally blown away by the water effect with the lights working.
This thing looks absolutely amazing!
