Summary
- Came with bad pressure gauge
- Tried to order replacement but seller sent wrong part
- Second replacement installed
- Think it worked? Needs to be checked out
- Pressure gauge was likely bypassed
- Missing manifold valve
- Replacement ordered but not installed

Summary:
- Clear area around it
- Put Ron back up
- Order lazy susan
- Vacuum gauge controller is bad
- Modified and in bad state: repairs may be difficult
- Looking to source identical replacement or something new entirely
Vacuum gauge
- Rewired with colored wires + better connections
- Still reading bad
- Negative reading (switch center)
- Low setpoint can be set (switch left)
- High setpoint can not be set (switch right). Shows same negative value as center
- Opened gauge
- Loose/missing cover screws
- Several wires have been desoldered
- Diode is hanging loose
- Bad state. Probably not worth further troubleshooting
- Try to source replacement identical module, or find another gauge with low/high set points
