Oh Man,

That was it. The resistor arrays were swapped around.

Ray, not your fault but I got confused by the text:
“For example, 10K array should read ‘L83S 103 xxxx’, “

I think i read the first part of the label L83S and made the [wrong] assumption that the resistor i was holding was the10k and i labeled it as such while doing the parts check.

Because they are so similar, It would have been super hand if those were distingushed in the kit.

But then again i am the only numbskull that made that mistake. I broke one of the arrays desoldering so i am waiting on an order from digi-key.

I’ll let you know how it turns out.

Thanks for your help everyone.

For the heck of it, i connected it up to the sprinkers and tried. I didn’t work. When i did a manual override on any of the 3 zones, the animation for each zone worked but they were not powered. I tested each zone with the volt meter and they did nothing.

I am running out of ideas.

I double checked the capacitors. Top right is the 10uF capacitor and bottom left the 2 identical 220uf next to the large 100uF capacitor. Could it be they are bad capacitors?

I don’t think i have done any of those things.

I have attached images of front and back.

Hi,

Yes I did those tests. The first was 5v. The second test was a little higher at about 3.8v. Though I have a crappy volt meter do it is a little hard to read.

Yes I have a 24vac supply 875mw. I tried it with a second power supply 24vac 700mW and the board behaved the same way.

I found that if I kick start the board with the USB I can then turn on the power and disconnect the USB and the 24v. Seems to maintain everything up and running.

Peter.
