help,...i have a question about my old boss ce-2

Ok, here it is. I have this pedal that hasn't worked in years due to someone stepping on the input cord at a gig years ago. I recently dug it out and would like to fix it. I have a stereo input jack and mono output jack... when I connect all the wires and plug a cord in and hook it up to my amp, there is no signal. However, there is a faint "click, click, click" sound that increases and decreases when the rate is increased or decreased. Anyone have any suggestions or know how to get this thing working properly again? Any pictures of the insides of one with the proper connections so I can see what it's supposed to look like? That would help. I appreciate any help on this. Thanks....

Open her up and have a look at the input sockets connections, there may be just a broken connection, or perhaps a terminal has sheared off inside
could be a simple "re solder" of a wire !!
You could probably fit a similar stereo socket, or there may be room for a new switchcraft "open" stereo socket.

Thanks. There are two wires that I have a question about where they hook up: a yellow wire and purple wire. When I hooked up the ground wires at first, the unit was on, even without a cord plugged in. Then I realized I had to seperate the ground wires on the input jack....now, what to do with the yellow and purple wire? There is also a white wire, which I believe goes to the output jack. Any suggestions?

From your description of it a few things are evident:

1) The LFO works.  Funny how, despite how much people complain about the LFO ticking being audible, sometimes, just SOMETIMES, it's an effective troubleshooting guide.

2) The audibility of the LFO tick means that your output jack is picking up whatever is coming out the audio path, warts and all.  (Incidentally, although the ticking may be the most audible thing about the pedal at the moment, once repaired, the ticking may be considerably less objectionable.)

3) We have no confirmation OR disconfirmation of BBD chip functioning status at the moment.

4) The absence of any audio output except for whatt the circuit itself generates suggests that the "blockage" is somewhere at the input to the device.  If you can find Q1, and you have a voltmeter (digital or analog), set the meter to a scale that will let you read AC in the range of 50-100millivolts.  Now stick your positive meter probe tip at the junction of R1 (1k) and R2 (470k), and your other probe to ground somewhere on the pedal (e.g., retaining nut for the jack).  With the guitar plugged in, give a few strums and watch the meter.  If the signal from the guitar is successfully reaching the transistor, you should see somewhere around 30-60millivolts AC when you strum.  If you don't, then clearly we have a case of the signal not making it to the board and the board itself may be otherwise very healthy and ready for duty.  If the meter indicates some AC signal fed to the board, then we'll explore other avenues.  For now confirm the presence of signal.

Incidentally, you would not believe how common it is for people to re-install a stereo input jack and connect the audio and battery lines to the wrong solder lugs.  Happens all the time.  That may well be what happened in your case.
