We bought it from Ham Radio Outlet.

Configuration, RRC 1258 / Re: Yaesu 857D Control head will not power up from RCC-1258MKII REV7

When you press the power button the yellow light over the MIC/AUX DOES NOT light.
As for the power supply concept: When the radio head is attached to the 857 and the Rig is powered the 857 works perfectly even though the TCC-MKII radio control unit is still attached, powered on and being monitored by the setup manager application.
The Status page on the web interface shows no interruptions of the up time when the 857 is powered on.
As a further elimination of power being the issue I have hooked up the 857 to an 880 CCA deep cycle battery, the control unit to the 20A power supply and radio unit to the supplied power supply and had no change. I also tried at 1 point The radio on a 880 CCA deep cycle battery, the control unit with face plate from 857 to a 500 CCA deep cycle battery and the radio unit to a different 500 CCA deep cycle battery.
The yellow light over the MIC/AUX never even blinks.
If the trigger signal from the 857 faceplate is coming in on Pin 1 of the TTL connector of the Control unit then power should be supplied to the radio head unit soon after on Pin 2.
This does not happen.

After trying the OEM PS, we used a 20 Amp Astron supply. It has enough power to run the complete radio on transmitting at full power.

New installation. All cables have been double checked for continuity and correct wiring. The RCC-1258MKII REV7 it will not power the display unit attached to the control Portion of the RCC-1258MKII.
My friend Peter, W2BIT, thinks he has narrowed down the problem. In the manual the diagram on page 147 shows that pin 4 at the control panel of the FT-857d should be 8V DC.
(As a side note this is wrong because Yeasu uses 9V DC.)
We get between 0.52 & 0.78V DC.
We first used the supplied wall wart PSU. When that did not work we connected it to a 20A 13.8V DC PSU, but there was no difference.
Pin 2 the power switch is @ 5V DC in standby and goes to 0.1 V dc when pressed, so the logic trigger is there for power on.
Jumper 1 is off, Jumper 2 is off, Jumper 3 is on and jumper 5 is off.
Any information would be appreciated.
