Hi everyone,
I am trying to diagnose whether my 3.3v reg is blown on my APM 2.6.
I have tested the IC2 port and there is 5v there, however at the reg itself, on pin 5 I found only 3.3v. I have attached a photo that will explain what voltage is where more clearly. The reason I think it is blown is I read somewhere that if there is a blown reg the compass offsets will be high, which they seem to be.
