Help schematics made in japan japan bass

[belacqua]

Hi, i'm italian, i'm new here. I have a problem with a made in japan bass, i think 60's. It has 2 pickups and 2 switch on/off to select the pickups. When i connect the bass to an amp there is only a noise and no sound. I've made a picture of the wirings and i've taken some photos. It would be a great thing if somone could help me to understand if the wirings are wrong and what is the right scheme for the bass. In this forum i've found a similar schematics but it seemed to me that the switch in that picture was 1 pole while the switches in my bass are 2 pole.
Thanks for the attention







Sorry but i cannot see the pictures. Maybe i've made something wrong?

First of all, check all the grounds, especially those on both ends of the wire to the output jack.
