Hi everyone, first a disclaimer of sorts. I was trained in electronics decades ago but my career took a different direction away from soldering irons. I still have a decent technical understanding though. However, I have a neurological disorder which is annoying when playing guitar as my hands are not very steady - this makes soldering a little more challenging on something as small as this pcb! But I went slowly and steadily checking all the joints as best as I could. So that out of the way. I have just built a FuzzDog Ross compressor and have several different (I think) issues. But I'd like to start with the first one which is making me pull my hair out. And I don't have so much to start with. I decided to test using FuzzDog's recommended method. So, testing my new battery it now reads 7.9 VDC (it was just over 9V at the beginning). The battery got hot, so I checked for obvious short circuits and didn't find anything except that somehow my live voltage wire to the board was loose so I fixed the solder joint. A continuity check between the V and G joints is good. There's no short circuit at this point. But when I measure the voltage between V and G on it reads 0.9VDC... Before I continue checking my board, I'd appreciate suggestions as to how I can lose 90% of my voltage at the entry point on the pcb. Does this still reflect a ground drop somewhere else on the board? Thanks!
