I just assembled an A/B/Y switch kit. The switching works. But there is something wrong with the LEDs. And I just can't figure out where I made the mistake.
This is how the A/B/Y switch works:
Switch 1 (A/B) switches between the two channels. The LEDs for A and B show which channel is on.
Switch 2 (Y) combines A and B. When switch 2 is engaged, the LED for Y is on. The LEDs for A and B show which channel you will return to when you disengage switch 2.

This is my problem (see below):
switch 1: LED A (red) OR LED B (yellow)
switch 2: Out A LED A (red) -> LED C (green) doesn't work
switch 2: Out B LED B (yellow) -> LED C (green) works
The weird thing (to me) is that on the Y switch the lug that powers LED C has voltage, both when LED A (1.6V) or LED B (1.8V) are on.
Any suggestions? Thanks!
