I thought you may have got the two resistors transposed, and that was why the readings were wrong....but as you said in a previous post, the joints were not good and you reflowed some of them. So as the resistors appear to be correctly placed, that is the 10k is connected to 5v and the 3.3k is connected to 0v, the junction provides the third state for AC indication..... As it is all working ok now, you dont need to fault find anymore.... :zap: :) |
