Dear all, total electrical newb here, and so can't tell if these readings are a problem or nothing to worry about. So stock smash done, resistance check good, all voltages spot on except for these three:
30 .020--will fluctuate as high as .025 and as low as 0.16
A6 -.321 (a negative reading?)
C6 -.265 (another negative)
Any advice appreciated. Cheers!
