Short in Radio Circuit

So, I was driving my Chevelle on a nice summer day, and all of a sudden my radio stopped working.

When I got home, I checked the Radio fuse and it had blown. Replaced the fuse, put the ignition key on ACC, the underdash lights blinked, and once again the fuse blew.

Tested the Radio circuit, yellow wire, at the radio-end of the factory harness and it is grounded. So, obviously I have a short to ground.

Before I start taking apart the factory harness, are there any other test points where I can check the circuit to help isolate the short? I am assuming that it is somewhere behind the gauges, but anything to try before disassembling the harness would be alot easier.

Thanks for all your help.

Ralph

Did you measure the yellow wire when it was unplugged from the radio and the fused removed? Is there anything plugged into the fuseblock?
Not sure if there is something else that goes to that fuse on a 70. If there is I’d check that next. Don’t have the schematic. Maybe someone else can look.

Think you may be on the wrong wire during your last test.
