Is there a schematic or something that I can check voltage and grounds at the module plug? I do know how to read a electrical schematic.
Thanks for all your help.

I measured the continuity of the switch per your last post.
White to black shows short all the way at the top of the float.
Brown to black shows short with the float about 1" off the bottom.
Red to black shows short with the float all the way at the bottom at the c clip.
I believe this should be correct?

In the process of checking this all out, I found a corroded connection causing a high resistant joint. I cleaned the connections with some electrical cleaner and WD40.
I put the system back together, and now everything works as it should.
Thank you for all your help and expertise.
