While performing a continuity test between Source and Gate pins of IRL244N of an assembled TX Unit v. 2.5 I see current flowing. I supposed this should not happen (?) and I guess I may have damaged the component by applying excessive heat while soldering.
Am I correct to assume this may be the cause of effects I am experiencing such as:
• LEDs being fed ~6v while 12v supply is ON
• FAN being feed 4 and something volts while no 12v source is present
• 7809 regulator having a reading of 4 something volts on the Output side while the board is being powered by USB only
I ask because yesterday I assembled my first unit and while testing (just with a DHT22) I discovered the TX led was not blinking, blown by excessive voltage (I have 510 Ohm resistors applied to R1 and R2). Having searched for a bridge in solder again and again and again and once more with no luck, I am now looking for a problem with components. The Diode seems to be OK.
Activating local debug over serial shows temperature and humidity being read.
The TX led blinks (switches off and on).
Any help/ideas would be much appreciated.
