There were a series of supplies that used 4 wires. Two were the DC + & - as
you describe and normally connected to pin 1 & 4. The other two were used
to switch the AC on/off via the switch in the radio. Then later the same
plug was used on the radio but a jumper inside the radio between pins 2 & 3
completed the circuit and no longer did the switch on the radio actually
turn the supply on and off.
Perhaps the fellow made some changes and didn't restore them prior to
returning the PS to you.

Subject: [TenTec] Triton IV Power Supply 252G Question
Hi
I have as my second rig a Triton IV 540 Analog. It came with
a 252G power supply which is now maybe giving me a problem.
My first question for the experts is: Can the power drop
to 0 volts because a wire between the PS and rig is not connected?
I haven't checked yet but while looking at the manual I noticed a
note to the effect that the power supply can be wired with four
wires, 12V + and - and a pair to allow the control of on/off to
on the power supply.
I loaned this rig to a fellow club member and when he returned this
one after getting his new rig it didn't work. I just don't want to
dig into something that turns out to be a simple plug problem. This
pair has the power wires going via the older Jones Plug connectors,
but didn't TT change to the inline Molex type plug at some time during
the manufacture cycle? Seems to me I remember owning a 540/262G combo
that had that kind of plug.
