Help. One of these days I will learn not to mess with things. However, today is not that day. Anyway, I bought a great EV 641 on EBay recently. Terrific mic - my only complaint is that the base is heavy and unbalances the mic. So, it sounds great, is easy to cup, but after a while kind of hard to hold. It occurred to me that perhaps the base could come off, and I decided to take it apart. Unfortunately, in pulling the plastic (?) casing off I separated the wires, and now I am confused what goes where. What I see are two yellow wires coming out of the element. One is still soldered to the on/off switch, the other is loose. There is a white ground wire still soldered to the switch. So, can anyone tell me where the other yellow wires goes?
Thanks.

Thanks Orphan. I actually found that PDF. The problem is I don't know enough about reading a schematic to understand what it is telling me. Probably another reason I shouldn't be pulling things like this apart.

Actually, looking at the schematic again, it appears that one of the yellow wires coming from the element (the coded one) should go to the same post on the on/off switch that the ground goes to? Does that sound correct? If so, I may have to bypass the on/off switch to put this back together. Would that mean the coded yellow would go to the ground screw on the base (like the white ground wire does)? Also, since the white ground only goes from the on/off switch to the ground screw, if I do away with the switch can I take a wire from metal around the element to the ground screw for a ground? Thanks again.

Seems like you could put yellow coded and white to lug, or just use the white wire.

Ok .... so what the schematic is saying is that
The ground and coded goto one post of the on/off. (The coded is basically the negative (-) from the element so that's normal)
The other wrire from the element goes to the other post of the on/off (this is the hot or positive (+) )
As the diagram is now it shows the mic in the on position.
When the switch is toggled (to off) it grounds the hot and turns the mic off.
Make sense?
Edit: After looking at it again. If you read the discription above for the mic model, the last sentence is something to the effect of ... the mic is shorted in the "off" position.

Just curious Rgsccr. How did you end up putting your mod together?

No Problem. Glad you got it working. 8^)
A broken mic is super frustrating.

Hi Orphan,
Actually, I just put it back together the way it was before. I may end up doing something different down the road, but it's too good of a mic to ruin so I think I'll wait. Thanks again for all the assistance.
