Quoted from RussMyers:OK, I sort of understand that schematic, but I have no idea how to actually test this in the machine.
Can you be more specific, or step-by-step?
Thanks,
RussM
Step 1: Read the links I provided
Step 2: Ask any specific questions that reading brings up for you

Quoted from RussMyers:OK, I've narrowed this down to misadjusted switches on the Z1 relay; I will try fixing that.

In case this is helpful
For a switch to work 3 things are necessary
1) When open, there should be a small space between the contact points (duh)
2) When closing, the long blade's contact point should push the short blade's contact point enough to move the short blade
3) The contact points should be clean, which they usually will be if #2 is happening
