Ok, Looking at the data sheet in section 11 VOLTAGE REFERENCE MODULE on page 68.
11.5 Connection Considerations
The Voltage Reference module operates independently
of the Comparator module. The output of the reference
generator may be connected to the RA2 pin if the
TRISA<2> bit is set and the VROE bit, VRCON<6>, is
set. Enabling the Voltage Reference module output onto
the RA2 pin with an input signal present will increase
current consumption. Connecting RA2 as a digital output
with VREF enabled will also increase current consumption.
The RA2 pin can be used as a simple D/A output with
limited drive capability. Due to the limited drive
capability, a buffer must be used in conjunction with the
Voltage Reference module output for external connections
to VREF. Figure 11-2 shows an example buffering
I am sure Mister-E can clear this up if it is the problem, now I am in new ground
