Using multimeter to find grounding issues

[Snowgal]

Does anyone have some tips for how to use a multimeter to track grounding issues? I’d like to be able to track between output jack and pots, pot to pot, pots to switch, pots to pick-ups, etc.

Any DC K reading/setting on the meter will do. You are looking for continuity (0k) to confirm a good contact. If the meter fluctuates or takes a long time but gets to 0 eventually this is a suspect joint. An error reading or the meter's open symbol means a complete joint failure.

Like he said above

Set any meter to ohms

The lower the number the better

plug a cable into the jack of the guitar

The tip of the cable should ne your signal path
The shaft ( the part under the plastic ring )
Should be signal ground

You should be able to read 0.1 ohms
between shaft and bridge
Then shaft and back of volume pot
Etc.
