[R-390] Wire harness

[Roger Ruszkowski]

Robert,
 
P114 is the plug on the harness  (chassis part )
 
J214 is the jack on the RF deck (RF deck part)
 
There is no J114 or P214
 
Give the lock ring on the plug a 1/4 turn to unlock it and unplug it from the RF deck.
 
 
The wire stripes  under the deck may not match the wire stripes in the harness.
The two separate assemblies (RF deck, wire Harness) may have been assembled
both miles apart and years apart in space and time.
 
More schematic reading Sergeant, I need to learn all.
 
 
You should not have to pull the RF deck to ring every thing out. You can likely do 
OHM meter readings to tube socket pins for the RF deck.
 
And read back to other wire harness plug pins or points through the wire harness.
 
There are no color codes in the TM.  Stripes will vary from production run to production run.
and likely day to day in production. That level of detail is not exact. It was just to make
production process reasonable. 
 
So when you get the plug back shell off the connector, 
you will hopefully find a wire with orange strip and a bit of shield on it
 plus a wire with orange strip and no shield on it.
 
If two of the wires have the same color and stripe, they likely both go to the same pin in the plug.
But they will both be the same with shields or with out shields.
One with shield and one with out shield are two different wires and circuits.


I should clarify more.

A= red stripe          180 Volt B+
B= black stripe       25 V AC Filaments
C= Orange stripe   RF Gain
D= shield/braid       Ground
E= Green stripe      AGC
F= Orange stripe
H = White

I though you would be able to match the bits of wire left in the back shell 
with the wire strands in the harness wires.

I've started the repair splice, I've looked in the manual and see whereJ214 goes to P114. Although no colors are mentioned. My dilemma is thatthe wire in the shield has an orange stripe, also there is another wirewith an orange stripe.I need to find p114 and trace out the wires to ensure I get the correctconnection. Anyone know where I can find P114? I'm assuming its under asub chassis which is going to involve me having to remove something tosee the underside.ThanksBob.P.S. Still haven't been able to fire the receiver up yet. I want torepair this harness first.
