FYI
Here are 2 of my posts from different threads about radio power drain.

Here is a solution to power down the radio antenna if you install a radio in the provided location. I posted this in a thread about battery conservation.
"I found that the radio antenna power lead is spliced to the radio power lead at the back rear of the fridge compartment. Remove the upper fridge vent, remove the two screws holding the plywood panel over the fridge cooling coil to access this area. I removed the splice between the two wires and extended the antenna power lead to the front of the cabinet where I connected it to the power antenna wire coming from the radio. Now the antenna is only powered when the radio is on. My Kenwood radio has a function switch to select radio, tape, CD changer/aux input and standby. The standby selection keeps the clock display running. If I hold this function switch down for several seconds, the power is turned off to the radio except for a very small current required to retain my button and tone settings and the internal clock time. I don't have enough battery drain to worry about and my radio clock is always set."
If you don't have a radio installed, remove the 12 volt fuse for the radio circuit.

I installed a Kenwood radio with remote CD changer in my 2720SL. I was concerned about the heat problem since the radio is installed in a small sealed compartment. I did three things to help the problem:

1) I installed a computer CPU fan to the built in heat sink in the rear of the radio. I had to drill the CPU heat sink to allow installation of a screw. It is fastned where the rear support area for the radio would be installed. I powered it from the power antenna leads from the back of the radio. These leads are normally used to raise/lower a power antenna. I also spliced the amplified antenna power lead into this connection so that the only time the antenna is consuming power is when the radio is on.

2) I cut four notches in the front of the refrigerator cabinet under the counter top overhang. I had to remove the counter top to cut the notches. First I had to remove the insulation over the frige heat exchanger including the plywood insulation support. Then I could get to the angle bracket screws that hold the counter top to the cabinet. There are two in the front of the cabinet and two in the back of the cabinet. After the screws are removed, the counter top has to be pried up. It is sealed to the cabinet with silicone sealant. While the top is off you can find the place where the antenna power wire is spliced to the radio power wire. I removed the splice and added a wire extension to the antenna power lead so that I could get the power from the radio. Counter top installation is the reverse of the removal.

3) After the counter is re-installed look through the radio cutout and use a long stick to put the insulation back in place. With the refrigerator outside vents removed you can see daylight wherever the insulation is not in place.

The Kenwood radio has a function switch on the front with three selections, ALL OFF, RADIO & DISC PLAYER. The ALL OFF function turns everything off but keeps the front panel lit since I have the radio light power lead splaced to the radio power lead. However, if I hold the function switch in for 3 seconds it will turn the lights off. The only power consumption is then to hold the button and tuning memory on line. I have not noticed any power drwin on my batteries even when the unit is stored for two months or more. I do have 2 golf cart batteries installed.

The other current drain (propane detector) is disconnected when the rear bath wall is folded down.

The CD changer is sitting on top of the water tank under the sink. I used a piece of the non skid shelf matting to hold it in place.
