Here's an old trick from a long forgotten source...
1. Remove Ground side battery cable
2. Connect test light between GRD. cable end and battery terminal.
3. If it lights...you have short somewhere!
4. Then, pull fuses one at a time (or disconnect accessory wires one at a time)
until the light goes out........
You could use a meter instead of the light I guess, but a light seems easier in trying to isolate the offending circuit.
