Re: Stupid tech... still have grounding issue! OMGBBQWTF?! Anyone help me with wiring
Checking a pot for proper values is easy but checking them for noise is much harder and I don't exactly know what causes the problem. Switches can be the same way. The only thing you can really do to check for noise is to isolate the problem.
Start by connecting only the bridge and one pickups ground wire to the jack ground and the same pickups hot directly to the jack hot terminal. This removes the switch anp pots from the circuit path. The guitar should now be hum free.
Now connect the pickup hot to the switch and run a jumper to the jack hot from the switch out. If the guitar is still hum free then it is in the pots. Now add the volume pot to the circuit and see if the hum returns. It's a trial and error thing umtil you find the noisy component.
If the guitar didn't hum before you added the new switch, thats a good place to start. I usually replace all the components in a noisy guitar like yours because the parts are cheaper than the bench time trying to figure out where the noise is coming from.
Good luck. Hum problems like yours are a pain to fix because except for the noise, the parts work fine so it's a hard thing to diagnose.
Make sure the new switch has a solid ground path as well. One component that isn't properly chassis grounded can also cause your problem.
