There are 2 Make/Break switches on the #5 Rollover relay on the Sequence Bank you found. Check the Make/Break switch that has a Blue-White wire on its middle terminal for proper operation.
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
