Wiring Diagram?

Harvey Kimray · Post by **Harvey Kimray** » 24 Oct 2009 8:43 am

I am trying to help a friend with a D10 MSA Classic Serial # 2C823 that he bought new about 1973. Someone installed 2 GeorgeL E66 pickups and has really butchered up the the hookups from the three position switch through the two tone controls and the 1/4" phone jack.
Does anyone have a wiring diagram they could send me so I can fix this mess?
Thanks in advance for your help.

I can look at a set of controls I have . I found a diagram by doing a search but don't remember if it had the controls in the diagram. I do remember that the jack only grounded to the body and did not have a wire attached to the jack. This was a 75 MSA.
Dwight I sent you a email. Scott

Actually I believe that there is one tone and one volume control and they should be after the neck selector switch. Generally speaking, one pickup hot lead goes into one side of the switch, the other pickup hot lead to the other side of the switch and the center is the output. That takes care of the switch. The center from the switch then goes to one side of the volume control and the other side of the volume control will go to ground. The center lug of the volume pot now goes to the center lug of the tone pot and then continues to the hot side of the output jack. Either of the other sides of the tone pot then connects to the tone capacitor (.047 microfarads) which then goes to ground. The other side of the tone pot is left empty. If either the volume or tone pot seems to work in the opposite way that you wanted it to, simply reverse the 2 sides of the pot in question- leaving the center alone. Tie all the grounds together and make sure that they go to ground somewhere or just connect them to the grounding part of the output jack. I hope that this helps. This post should probably be moved to the Electronics section.

Thanks Jim:
This is excactly what I was looking for. I debated which topic this should have been listed in and had second thoughts that maybe I chose the wrong one.

Here's a link to a diagram I made for myself when I had my MSA S10. Sorry no pickup selector in the diagram.

Here's a "generic" schematic from the Carter website:

Here's a color version of Jim Palenscar's two pickup wiring diagram with selector switch, volume and tone pots.
