Seems like I'm still not out of the woods with my TS-808 pedal, the pedal seems to function fine when my Carson 9V DC Plugpack adaptor is plugged into it, but when I try to run it off it's internal 9V battery it doesn't seem to be working properly, I've tested the 9V battery and it is fine, so I'm thinking that it's either the replacement battery clip, or a bad contact in the DC in socket, so, I'm going to have to do some more detective work with my multimeter this afternoon.
A lot of the times with these pedals there's a couple of contacts in the DC in socket that disconnect the battery when a plugpack adaptor is plugged into it, when the plugpack is disconnected from the pedal, the two contacts short-together and connect the 9V battery up to the circuit-board in the pedal, if these contacts are dirty then the contacts won't properly short together, I might have a replacement socket that I can use in amongst my bits and pieces.
Update:
After a quick bit of detective work with my multimeter, I think I have found the cause of the problem, it appears that the two contacts in the DC in socket that connect the + terminal of the 9V battery to the power in on the circuit board, aren't making proper contact like they're supposed to, checking the continuity of the contacts with my multimeter set to continuity test produces no beeping sound from my multimeter, thus indicating that that there's no continuity between the two contacts when there should be, because of this the circuit board isn't getting power from the 9V battery when it's supposed to, the reason why the pedal powers up with my Carson 9V DC plugpack adaptor is that the plugpack adaptor is bypassing the battery when it's plugged in, so, replacing the DC in socket should fix the problem once and for all.
