Greetings All,
Does anyone have electrical schematics for Whiting Jacks? Copies for sale? Need to resurrect a set of jacks ... wiring is pretty bad.

The first place I would check is Whiting:

The first thing to do with old screw jacks is to determine the amount of wear on the lifting nut. Whiting has a procedure and maximum wear limits. When you contact them about a wiring diagram, ask them about the lifting nut inspection.

Thanks for that, David ... I have heard scary stories about those things giving way!
