Yup, it's most likely bad... I guess you haven't tested it?

If that all tests out try to borrow a known good one or find someone with an oscilloscope and the specs to test it thoroughly.

Also check the vacuum line coming off the ps pump To the bottom of the accordion pipe. My old 7m did that when I would forget to hook that sneaky little thing up.
