Finding Short from 60Amp Body 2 fuse

[buickcoburn]

I have a 1995 Buick Roadmaster Wagon and have been experiencing a short that has been draining my battery for the past couple of weeks. I went out and bought a test light and found that the 60 amp, body 2 fuse in the underhood fuse compartment is where the short is isolated. The issue arises that none of the fuses on the driver-side door fuse panel, connected to the body 2 fuse, extinguish the test light. The only thing of note that happens is when the fuse to the radio(fuse #30) is removed, a buzzing noise will start.; this only happens occasionally when the fuse is removed. Has anyone experienced a similar issue or have any suggestions for what may be causing the drain?

Not sure that is a valid test. A car with any kind of computerized system can draw up to 50ma and be considered normal. You need to use a multimeter.
