Hi Joel,


Have you disconnected the positive lead at the radio and battery to 
check to see if there is any continuity from the positive power lead to 
the vehicle chassis?  There should be none, if there is, follow Matt's 
advice on, inspecting the harness to the radio or, abandon the one your 
using and reroute a new one, whatever is easier.  Good Luck
