[Heathkit] Help D104 update of problem

[OTAKEBI at aol.com]

Well, Gene I have gone over the wiring 3 times all is good with that I  think.
The question remains why I get continuity between the audio white and  shield.
It does not matter if I push down on the PTT bar or not.
It makes a great connection to ground.
I went to the top of the mast and I see that pins #1 and #2 are  jumpered.
Pin #1 is grounded and pin #2 is yellow wire which goes to lug #2  on the bus 
at the bottom of the mic.
Buss lug #2 is jumpered lug #1 which is grounded to base.
If I run the probes of my ohm meter from lug #6 to lug #2 I  show continuity 
to ground.
And, that should be the case since the yellow wire on lug #2 goes up the  
mast to pin #2 which is jumpered to pin #1 on top of mast.
So, I guess unless you tell me different the wiring is okay.
 
If so I should wire the mic plug for my SB-401 as follows.
White = audio
Shield = ground
Red and Black (connected together) = PTT
 
The R/E should be on R
 
Does that sound right to you?
 
I think the crystal element may be the problem.
It is in bad shape and don't know how to test it to be sure.
I tried to find a replacement but can't locate one.
I will probably order a Heil Rag Chew element like I have in my  other D104 
and look for a good 10-DA head later.
I went to radio shack and they sell an electret but I would have to splice  
in to the positive mic line and pull power from the 9 volt battery.
I will try to find a ceramic element in my junk box so I can test  if the mic 
is working.
Let me know what you think about all this.
I will also post this to the list to see if the fellows can help me out  too.
