Quote from: FABphones on January 14, 2019, 02:15:15 PMMy initial test is simple. Plug it into the wall, so, if it has a line cord, before. If it has none then when I open it up I will have already begun the clean up so, midway, after sanitazing and attending to whatever I find inside - usually cut line cord. But, a tree took our phone line down before Christmas, so at the moment, *after.*I am looking for another means of testing that doesn't require a landline. I am looking for something ex-GPO / BT that will be suitable. UK members, any ideas?

If it has a modular line cord, it goes right into the 616. If a 4 prong old adapter, I open up the phone and connect L1 and L2 (and possibly move the yellow wire) and use clip wires to an wire to modular adapter box that I made that then lets me connect a phone without a modular line cord directly to the 616.I check for a dial tone. If that is there, I call the phone to see if it rings. If it rings, I answer it to see if the voice circuit is working. If it doesn't ring, I still answer the phone to see if the voice circuit is there and if so, I have a ringer issue.If the ringer did not ring, I attach my DSine ring generator to the ringer leads to test the ringer directly (in stand alone mode). If it still doesn't ring, I have a ringer issue. If it rings, I have a circuit issue.If the voice circuit does not work, I have an issue in there.If it has a dial tone, I then try to dial out to another phone on my 616. If it doesn't ring another phone, I know I have dial issues. If it does ring the other phone, I hook then hook up L1 and L2 to Audacity to determine the actual dial speed (PPS) and break/make ratio.With all of the above information known, I am ready to take the phone apart for cleaning, issue repair and total restoration. The above takes about 5 minutes to do and give a good baseline on the phone as received.I've found that these steps define the phone as received and always eliminates the question of "did it work as is or did I do something to it when working on it" if the phone does not work after restoration. These steps also tells me what needs to be done on the phone.Just the way I approach a new to the bench phone regardless of its condition.

This initial hands on 'shake down' is the most exciting part of the purchase, other than the purchase its self!
