Active/Passive Push/Pull issue

[kodiakblair]

Hi folks

 

I'm hoping for possible causes.

 

Bass is a Belcat/Ming 2 band preamp,fairly common in low cost basses. With the push/pull pot in the "in" position both pickups are working. When the vol pot is pulled only the neck pickup works.

 

any ideas where I should start looking for problems ?

 

Regards kb

First off, just have a good look over the terminals on the switch section of the pot.

Pickup hots are on two different lugs. I've 1 on row 2 and 1 on row 3. On this jpeg both go to the middle.

Another difference with mine is the jumper,it runs lug 1 on first row to lug 6 on 3rd row.

Swapped both hots to the middle like the wee picture above. That sorted it.
