Wiring short problem

I believe I have a short somewhere. The battery runs down fast if I don't disconect it. When I run the engine the voltage gauage becomes less negative (slightly more so when the engine is racing.)

Anyway I think I have a short somewhere: The rear dome light has always been a problem in the past in that it would always blow out any new bulb. I have recently had most of my dash indicators stop working (All that are working are the Voltage gauage and the speedometer/odometer). These are clues for a possible short that I know of. I've done a curiory look at the wiring and can't see anything.
I looked for the fuse box so I could isolate things but couldn't find it.

Can somebody tell me where the fuse box is? Or what better yet what the likely problem is?

I have the same problem with my 91 aerostar, what was the fix ?
I removed all the fuses and still have a 14 volt draw:{
