Apologies for the misleading info.
I had forgotten that this was a 575 and was thinking about the D104M6 that has a little round volume pot in it.
your mic has a volume and tone control, but they are sliding faders, not round potentiometers. they do the same thing, just shaped differently.
I also only gave you part of the schematic in that post on page 1, as we were only dealing with the PTT switch itself at that point.
here is the full schematic of the 575M6 mic:
[ATTACH=full]59090[/ATTACH]
see that arrow towards the left side of the diagram that is pointing at that jagged line labeled "2M"?
that is the schematic symbol for a 2 Meg ohm variable resistor AKA potentiometer or "pot". many pots are round like you would see on the face of your radio, but some are sliders like you'd see on a mixing console.
your mic has the slider type.
the 2 meg ohm "pot" is for your tone control.
now if you look to the right a bit, you'll see another one of those arrows pointing at a jagged line, this one labeled "5K".
this is your volume control slider and it is a 5 Kilo ohm potentiometer.
the positive lead of the battery is connected to one of the terminals of the volume control slider.
sounds like you already have that one done correctly so just leave that one alone.
we are going to need to turn the PC board over now so you can access the solder connections of the PTT (push to talk) switch.
after determining which of those solder connections is pin 9, using my post from page 1 to figure out which pin is which, you will solder the negative lead of the battery connector right to that solder connection.
you may have to add a little length of wire on to that negative wire in order to reach around the PC board, and you might need to route it around a bit in order to get everything to seat back into place.
if you need to, you can take a picture of the other side of the PC board where the switch solder connections are, and i can help you determine which one is pin 9.
hope this helps.
