Gah! Personal #Hilary damage. It turns out the waterproof box housing my #DIY retrofit electronics for an outdoor brew #fridge is Indeed waterproof.. and was full of rainwater! (Somebody had the bad idea of putting the cable entry on top... and failed to seal it!). Just burned 3 hours fixing it.
Luckily, I had another controller (the AC version) sitting around (bought it for this, but had no AC supply, so bought the DC version). It ends up there is only one component difference between the two, an AC to DC converter. Removed rhe converter and wired the output identically.
Also fried rather 5V to 12V converter, but I bought the 5 pack figuring I would use the others elsewhere. Just hooked it all up and back in business (took 3 hours to do all this). Doh!
One thing learned froma ll of this, however, is there is a big pad marked "5V" on the back of those controllers (which are labeled as 12V controllers).... so somewhere they are converting 12V to 5V to run the board, which means I really don't need the 5V to 12V converter I have in there. #mumbling about #electronics
@J I also suspect I can dump the 5V to 12V converter, there is a contact labeled "5V" on the inside there and I'm pretty sure they're converting 12V to 5V in there.
@exador23 Yes, on a GFCI circuit. No, it did not trip anything, and it did not affect the refrigerator at all. The +12V input line acted as a fuse (!). Might put an inline fuse in there as a result. So... no one getting fried and nothing turning into smoke = good news.
