Hello, I am building my K1, and have completed the first section of the build, and am at the DC Voltage check stage on page 30 of the manual. While the unit seems to have passed the actual "smoke test" aspect of the initial application of 13.1V of DC power, I am getting 0V DC readings at P1 pin 15, and also U3 pin 6. Furthermore, U3 pin 5 only reads .015V DC, rather than 3.8 - 4.2
In chart form as the manual lists: Test Point (+) DC Voltage My DC Voltage P1 pin 15 5.8 - 6.2 0 P1 pin 16 (supply - 0.3V) 12.79 (correct) U3 pin 5 3.8 - 4.2 .015 U3 pin 6 7.6 - 8.7 0 Also, In the resistance checks on page 29, I am curious about a couple of readings: P1 pin 8 should read >100k. I am getting 1.77M, which certainly is greater than 100k, but it seems excessively so. Also P1 pin 16 should read >1k, but I get 5.18M, which again is >1k, but it seems outrageously high, so I'm guessing it's tied in with my issue above. Also, U3 pin 5 should read >10k, but I get another quite high reading of 5.15M. Finally, on U4, I'm getting 5.13M on pin 6, and 5.6M on pin 7. If anyone has some ideas for me to try to track down my problem I'd appreciate it. While I have tried to be very careful in treating static sensitive components, I wonder if I may have accidentally damaged one (or more). Thanks!
