Tele Wiring Question

Last Saturday, I got a stock reverse plate unreversed and the tech did a whole lot of rewiring along the way. I opened her up and found a loose ground wire for one. So I refastened that. Now, I have attached a Tele wiring diagram and I'll explain what is different on mine (in the next post) and maybe someone can help to explain whether the difference matters.

1. instead of the wire running from last (right) switch point to Volume, mine runs from first (left) switch point to Tone.
2. all my grounds run to Tone, except the body ground (which runs to Volume).
3. a very small bit of solder was connecting points 2 and 3 (from left) on the switch, which I have now cleared using my fingernail to break the connection.

Do the diffs above make any difference?

First question is: does the guitar seem to work OK? P'ups switch back and forth OK, combine in switch middle position, etc? Assuming the answer is yes, the answer is no, the hookup you describe shouldn't be any different, provided:

1. The wire that runs from the volume to the tone pot is in place as shown in the diagram. It makes no difference if the switch wire goes to either terminal.
2. Again, should make no difference. The pots cases, mounting threads, etc. are all grounded together (more properly bonded together) by reason of being screwed firmly to the plate. If the plate is not metallic, yes, it would make a difference. I know of no reason your tech would have run the "body" (assume it's the ground wire from the bridge, yes??) ground wire and soldered it to the volume, instead of where all the other grounds are soldered. In any case, electrically, for all practical purposes, the back of one pot is the same as the other pot.
3. Sounds like a bit of sloppy soldering that got overlooked. If picking off the solder crumb did not change any tone or function of the switch, no problem, and it should make no difference. There are terminals on the switch that are to be connected together, but I think it would have been obvious if your tech had bent the terminals and soldered them together, instead of the more common method of using a wire to bridge them.

Thanks very much for your post. Does the guitar work ok?

Well, when I got it back, I thought I was getting more hum/feedback/crackle than usual. Secondly, I can't tell any difference in sound between middle and bridge positions.

When I refastened the volume to the body (wood) of the guitar, I thought there was less crackle (but maybe that is a red herring - see below).

One existing problem is that when I press down on the 3-way switch, sometimes the sound goes very quiet, or crackles, or goes completely dead. So I lift up the plate and it works again (there was not much room in the cavity once switched) ... now I am only fastening the control plate lightly, so that everything still works.

Apart from those issues which I might be able to work around, I hear absolutely no difference between middle and bridge positions. Tonight I'll try raising the neck pickup to see if I can get a different sound in middle position (however, it sounds like middle and bridge are engaging both pickups - but I need to check that).

Great news. I found this post http://www.tdpri.com/forum/tele-technical/3051-bridge-middle-positions-sound-same.html#post22575 and it helped me find the problem. It turns out my neck AND bridge pickup is engaged in both middle and bridge positions - back to the tech on Saturday!

...back to the tech on Saturday!

You're going back? Didn't he not make it work right in the first place?. Spend a few bucks on a solder iron and do it yourself. It's easy and you really need to know how to do this type of basic maintenance anyway. Once you know how to solder, and that's easy, you'll be able to try out other wiring options when you want. Go for it my friend.

@Leroy. Thanks, your encouragement helped me solve the problem. Although I didn't end up soldering, the intention to do it led me to the solution ... see here: http://www.tdpri.com/forum/telecaster-discussion-forum/334369-tele-wiring.html#post4259099
