Hi Marty,

Are all your switches original? Even if one is substituted for a SPST type switch the combinations won't work as designed.

Basically the power supply side poles of the switches are all common. think of them as connected to a bus.

The isolated poles (isolated from each other) on the output side is what makes it possible to have the various lighting combinations with just one switch thrown.

If all switches are original, it might be worth putting a multimeter on the switches to check the continuity that all the 3 power supply terminals are common to each other and that all 3 output terminals are isolated from each other.

Also check that all the jumps are correctly wired in and all jumps present.

Hope this is of some help or points you in the right direction anyway.

Cheers,
