So I think that my phone addiction is worsening. I now want to take the next step and fix the only phone in my collection (which now stands at 22 phones

) that doesn't work. It is a junker 5302 that I picked up for like $10 on eBay. It gets a dial tone right when plugged in, but the phone acts like the hookswitch doesn't exist, in other words, you cannot break the dial tone at all, either with the dial or the hookswitch. when the dial is rotating, the dial tone cuts out, then comes back when the dial returns to rest.
In an effort to troubleshoot it myself, I took it apart and also took my 1941 302 apart and compared the 2 to try and see what the problem is. I found that my 5302 is wired vastly different than the 302. The hookswitch itself appears to be making contact, which leads me to believe that there is a wiring problem (the 302 only has 3 wires running to the handset, while the 5302 has 4, so an apples-to-apples comparison is difficult for my [relatively] untrained eye, also, it's much harder to see how the 302 is wired because the wires are run all bunched together. the 5302 is a mess inside, with wires running everywhere). I've included a picture of the 5302's network below....any ideas? I really want to get this phone working!!!
