Figured out wats wrong with my wiring - made me "lol wtf!?"(need help fixing tho)

TimSE · 05-23-2008, 01:15 PM

Right
i think EMG have all their wiring diagrams for active pickups wrong - as bold a statement as that is.

i followed this diagram and double checked it after and i wired it up like this corectly

Cool ... no Tone ... As in the Tone knob is doing nothing (like its bypassed

) im not 100% but im fairly sure the capasitor is ment to go from one of the tones side lugs to the ground on top of the tone knob? not to the volume middle lug?

After wiring up the above ^^ i also have a killswitch to disconnect the battery as well as the signal...

When i turn the killswitch OFF (disconnecting it) i still get some slight sound. as if the volume is only just on ... very weak signal BUT if i turn my TONE knob off it goes ...

when my battery/killswitch is disconnected my TONE is now a volume for the non-battery signal

i hate wiring

anyone have any ideas how to fix this? i like my tones

And to confirm its not my wiring i have 2 guitars with this problem. exactly the same for each

P.S. i have 2 EMG 707s - 1 normal and the 2nd is the new 707TW coiltap (for both guitars)

If the tone control is not working you either have a cold joint on the pot, or made a mistake. Triple check your connections.

cold joint? as in loose connection?
and have checked over it all so many times already - is exactly as it is ment to be from the diagram

WarriorOfMetal · 05-23-2008, 09:45 PM

the capacitor is supposed to go to a lug on the volume pot. it should be connected to the same lug on the volume pot as the wire coming from the pickup selector.

Man, there are so many different ways you can wire guitar electronics. I used to have an 81/89 setup in my Jackson and it took quite a bit of work to get it wired correctly, and yea, their diagrams are quite flawed. Wish I could help you right now but I have a killer headache from last night...

ibznorange · 05-24-2008, 03:35 PM

put the killswitch connections there.

dealing with pole 2's connections, (black wires) where it says to jack, clearly connects to the hot line at the jack (the one coming off the tone pot lug)
where it says to pots/switch thats the other end of that line. connect that to the actual lug on the pot. that way when the switch is disengaged it goes straight through. where it says to ground connect to the back of the tone pot

TimSE · 05-24-2008, 04:15 PM

?? where your saying to put the 2nd BLACK WIRES connection isnt the hot signal. its the ground

i want it between the volume Lug and Jack Tip..ya? as thats the Hot line (on the diagram above)

dpm · 05-24-2008, 05:26 PM

EMG's diagrams are not flawed in any way. There are two ways you can wire a tone pot to a volume. One is how EMG supplies them prewired, with the cap between the vol pot and lug 2 of the tone pot with lug 3 earthed. The other way is to directly connect the volume pot and and lug 2 of the tone pot and place the cap between lug 3 and ground.

From the symptoms you're describing it seems you have a problem with earthing/grounding. The tone pot not working points toward the case of the pot not being earthed, and the killswitch allowing a weak signal through points toward it not earthing the hot signal. EMG's still have a tiny amount of output with the batteries disconnected.

Another possibility here is that you've overheated either the pot or cap, but that still doesn't explain the killswitch issue.

Max is talking about the black wires in the killswitch diagram.

dpm · 05-24-2008, 05:36 PM

BTW, if you can get a clear photo of the wiring that might help

TimSE · 05-24-2008, 05:57 PM

Thanks Dan
think it might be a earthing problem then
only thing is its the same on 2 guitars
the guitars work otherwise and the killswitch is still dosconnecting the batterys which was all i wanted it for really so i il put up with it til i can get them sorted properly.

Thanks very much for the help tho guys
most greatful

EDIT: i would get some pics but my cam is crap as close up photos and would bo too unclear

TimSE · 05-24-2008, 06:11 PM

Right
just re-wired my killswitch and tone and the tone is working now but as avolume so i think its a Cap issuse maybe? the killlswitch is the same as it was

dpm · 05-24-2008, 06:41 PM

Sounds like a dead cap, I assume you have a spare from the stuff bundled with the pickups? Might even be worth changing the pot too because you've likely put a lot of heat into it and they don't take kindly to that.

With the switch, it should work, perhaps there's a cold solder joint as suggested earlier. You could swap the wires so the signal goes from the pots/switch to the bottom lug, and to the jack tip from the middle lug. This would earth the tip of the jack directly, though I see no reason why it shouldn't work as is

dpm · 05-24-2008, 06:53 PM

BTW, a cold solder joint looks dull and grey instead of shiny and silver. They can be hard to spot sometimes. There's also a possibilty the switch may be damaged and the contacts not separating properly.
