mrtrew Posted July 10, 2010 Share Posted July 10, 2010 Hi, Just like Icarus I'm feeling the burn. Reason being I took it upon myself to rewire an Epi 335 Dot and have not been able to get any sound out of it (feedback, yes). Have attached some pics would be so grateful if anyone can see any blunders. Link to comment Share on other sites More sharing options...
animalfarm Posted July 10, 2010 Share Posted July 10, 2010 Gotta eyeball this for a few minutes, hard to see pot tabs on some... Which wiring diagram did you use? Link to comment Share on other sites More sharing options...

animalfarm Posted July 10, 2010 Share Posted July 10, 2010 I saw what I saw, then pounded my head against wall to clear head, looked again. It's really hard to get a CLEAR view of your guitar jack connections, BUT.... It appears that the Ground wire and Hot wire on your plug in jack are backwards. The wire going from the selector switch that has only ONE tab (GROUND) should be going to the tab on the guitar jack that is attached to the center ring. And the wire going from the center tab on the OTHER side of the selector switch goes to the OTHER guitar jack tab. I'll look again.... Link to comment Share on other sites More sharing options...

Just reverse the black and white leads on the output jack and all should be well. L8R, Matt Link to comment Share on other sites More sharing options...
mrtrew Posted July 10, 2010 Author Share Posted July 10, 2010 The Black wire going to the jack is going from the single tab on the switch to the innermost tab on the jack, should be right I think. can try to get a better pic Link to comment Share on other sites More sharing options...

L8R' date=' Matt [/quote'] MUCH BETTER PIC! Sho' Nuff... There are 2 sides to your Selector Switch, one side has one tab only (GROUND), the other has THREE tabs, with the Center Tab going to your plug in jack. Your pics show that the Selector Switch ground tab has a WHITE wire, and the wire needs to go to the tab attached to the center ring on plug in jack. AB Man confirms, just reverse the wires on the plug-in jack, they're backwards! Link to comment Share on other sites More sharing options...

animalfarm Posted July 10, 2010 Share Posted July 10, 2010 The Guitar electronics diagram can be misleading as it does NOT show wire color on a 4 conductor pickup. Use THIS: http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=2h_2v_2t_3w I had to drag out a copy of the schematic to verify. The RED and WHITE wires from your pups should be tied together. The GREEN and BARE wires go to GROUND. The BLACK wire goes to HOT on your Volume pots!!!!!! I believe this will solve your problem. LOOK at Schematic Wire COLORS in link, compare to yours, looks a bit different as to how they're wired up! Link to comment Share on other sites More sharing options...
mrtrew Posted July 10, 2010 Author Share Posted July 10, 2010 I have some Wizard Novatron pickups instructions say: 'Black= Start of screw coil Red= finish of screw coil White= Start of slug coil Green= Finish of slug coil' Then goes on to say: 'To wire conventionally in series join red and green, insulate and forget.' Have had them working like this before with the original wiring (WHY DID I CHANGE!) So they should be fine unless damaged somewhere along the line Link to comment Share on other sites More sharing options...

IF you will note, in post #14 I suggested the SD diagram. It is in post #15 that mrtrew IDs his pups as WIZARD Novatrons. As I have no experience with the Wizard Brand, and the Wizard Website doesn't provide any Schematics, I am unable to go further. Rockfield pups are the same way, screwy wiring. ANYONE out there who can pull off an "assist"? Edit: I would have to default to the Wizard instructions. Under normal circumstances, I would plug a short cord into plug jack and start taking pup resistance readings as per this method, just to see what I am ACTUALLY reading vs what I am SUPPOSED to be reading: http://forums.epiphone.com/default.aspx?g=posts&t=11364 Hey folks, at least I'M TRYING TO HELP this gentleman!!!!

mrtrew Posted July 10, 2010 Author Share Posted July 10, 2010 Scratches I don't mind, noise is even better. I do use a towel when not taking pictures though stops solder getting to the magnetic poles too Link to comment Share on other sites More sharing options...

I just didn't want mrtrew digging himself a bigger hole... BTW here's color code info on some of the major pickup manufactures courtesy of StewMac Actually, I think I see the problem. He's got a ground wire going from the switch to the jack, but it doesn't look like the switch is grounded!!! That black wire going from the switch to the jack needs to be grounded to the pots. Snip in in half, and solder it to one of the pots. As far as I can tell from the pictures, the ground ain't going to the jack!!! Link to comment Share on other sites More sharing options...

Jerrymac, you just made me Laugh my @ss off!!!!! :- :- I spotted the reversed wiring at the guitar jack, but THEN got off on a tangent looking at pot tabs, and wiring. Totally spaced out the missing ground. The switch ISN'T tied in with the ground circuit with the pots!!! Couldn't see the Forest for the Trees. mrtrew, Ground circuit - 3 way switch grounded to back of any pot. All pots grounded together. Bridge ground wire soldered to back of any pot. ground wire from back of any pot to inner tab (ring) on output jack. (and of course, your pups are grounded, too...)
