Hi My P3 has all of a sudden stopped powering on. I am not sure what the issue is and I am asking here to see if I can determine where the issue is. I have done the usual steps of verifying the power supply, holding down the power button for more than 10 seconds with no resolution.
Using my bench power supply, I see that there is 0 ma current draw at the start. Pressing the power switch will increase the current draw to around 260ma as long as the switch is held down. The test points on the I/O board (and power supply) show 12V, 5.0 V and instead of 3.3V shows 2.6V. That is about the extent of my capabilities to trouble shoot from the schematic. I am wondering if this is just the power supply / IO board? It would seem that Elecraft still has these in stock.
