I have a UPS26-99fc that is about 2 years old, can't remember for sure where I got it, the speed selector switch is acting up and will randomly lose its connection, does anyone out there have a schematic of how the switch is wired into the darn thing? I am fine with adding a different switch, I just need to know how the darn thing is wired, I tried pinning it out but things aren't making sense. thanks in advance
 
the lever is not moving, the internals of the switch are losing contact, the guts have started coming apart
