Multimeter shows pots resistance instead of pickup resistance when conn to jack
(1/5) > >>
Rango:
Hi guys. So i rewired my guitar for 50s wiring and i connected guitar cable to output jack and measured it with multi-meter to see if pickups are working.

The multimeter is showing pots resistance of 500k at volume of 10 but it should show pickup resistance instead. When i switch to neck and then bridge pickup it always tops out at 500k which tells me it's measuring pots resistance. When i roll volume pots the resistance is obviously changing but the resistance is between 50 -500k omhs and pickups are 8.14k omhs and 14.40k omhs.

I have measured the pickups resistance before installation and they were working at 8.14k ohm neck and 14.4k ohm bridge so i know they were working before install so i know they're working.

Did i ground pickups somehow or what have i connected wrong that it's not measuring pickups resistance when playing with pots volume?

I don't have an amp yet so i can't connect to it and test it but multi-meter, the tool of troubleshooting is showing pots value instead of pickups value when connected to output jack so I'm assuming something is not right here?

What did i do wrong in electronic wiring? Any help in troubleshooting this would be greatly appreciated.

I can't see enough detail to help.  But check that the grounds are connected properly.  If the pickup is connected to the pot and the pot rotated, the ohmmeter should see the resistance change.

Otherwise you have a miswiring error.

I think the pickups are not wired right - each one (bridge, neck) has two wires? (red,white) and you soldered them to the same spot? One should go to ground i.e. white, and the red goes to the pot's wiper.

I would find 14AWG house wiring as too thick for a ground buss wire, it just needs so much heat to solder without cooking the pots. You can attach other grounds soldered to the wire between the pots, it's less heat.
Best not to have a loop or circle in the pots' grounding wire, try a letter "C" instead.
Cubdriver:
Do your pickups have white and red wires only?  It looks like you have both connected to the lower terminal on each of the volume pots - they're shorted.  One of them needs to go to that lower pot terminal, and the other to the grounded side of the pot.

I *think* this is how you have it:




And this is how it SHOULD be wired:
