I have saw the wiring for a Turner + 3 to a Cobra 25.
When I wire it up as stated and I plug it in the radio I get
a loud hum and the needle pegs to the right.
Here is the way I wired it up.
1-sh/red
2-white
3-blue
4-black
Any suggestions?
It's not the radio cause I tried it on my other Cobra 25 which is brand new.
Thanks

That is the correct wiring for that mic/radio combo, check for short circuit in the mic connector area meaning where you soldered in the connector, very small wires are hard to see sometimes.

This is from the Turner Wiring Handbook-

1-shield
2-white
3-black
4-red

I was wondering about the shield being connected to the red or transmit.

That's the same as my super sidekick (I looked inside) and I assume they like many other manufactures used different mic cords with different color wires.
