Quoted from Robertbucs:The 1st photo is with Multimeter set on 20k and the 2nd photo is with it set on plain 20.
- First image result should be disregarded. It's a measurement of resistance not potential difference (voltage).
- Second image shows +0.55V (as you've measured it). Next step is to check continuity across the fuse. It's probably blown. Set your DMM to 200 in the Ohms section (south as you look at the setting knob). Put your leads across the fuse (F115). Report the reading. You should strictly remove the fuse from the holder but for this circuit it is not necessary.
