I am testing the pods and switchover valves for my 1984 300SD.
I'm using a mityvac and hooking it up to the switchover valve pointing away from the dash part "A" shown in the link below.
One of the switchover valves failed this test and so I tried switching wires with another valve and this valve passed the test. Bad wire?
My valves are numbered 1-6. What do these go to? The diagrams I've seen only have five switchover valves. I guess for a W123.
Thanks, Jeff
