My resistance readings range from around 1k ohms to about 500 ohms. Those were found using wire with alligator clips. I mixed and mixed and mixed... I’m sure the graphite sinks to the bottom, so sometimes I re-mix. Will have to paint a 4th time? 😔 Sigh, but I’m learning so that’s good. When I touch the wires together, the display starts at 0.000k ohms and the number fly upward to like 12 ohms, and then decrease to around 0.1 ohms. Is this the auto ranging terribleness? Maybe I’ll try to remove auto-ranging in a bit. Gtg now.

measuring continuity is fine if you get the beep but without the beep a resistance reading tells you what's going on

Aahhh.... no, for some odd reason, after repainting a 4th time, it’s dry now, and, when using the probes with the covers removed, so that the long metal rod is exposed under each probe tip, resistance readings are now like 400 ohms to 1200 ohms. Hmmm... I’m using Anita’s water based Acrylic craft paint; is it eating the graphite? Or, maybe... I don’t understand... Guess I’ll add another tablespoon of that powdered graphite lubricant and paint a 5th time... thetragichero gave me the impression that it’s a 2:1 ratio... so another tablespoon would get me closer to that ratio. Maybe my ounce measurement is way off... hmmm... 😔

On second thought, I’m going to quit now, bc adding another tablespoon may make it too thick. Something must be wrong with my ounce measurement. I’m not giving up and will paint a fifth time. 👍

Hey Unreg,
I think you’re good to call it quits. You’ve got sufficient graphite in there to do the job it needs to. It will be fine.

Really frets? 😳🙂😀 Thank you so much! 😊 I will reassemble my guitar instead of painting a 5th time. 👍 Sigh of relief.

Hmmm... frets, you mean there is enough graphite to shield the cavity? I’m comfortable with that. But, my guitar does NOT have a ground wire that grounds each pot case. So, since the surface is metered at a minimum of 400 ohms, does that mean my pots’ cases won’t be grounded? Do I need to repaint? Thank you for reading. 😊
