I am replacing a defective radio with a Pioneer AM/FM/CD player. The Pioneer has the memory wire, i will hook it up to power and install a switch to cut off the constant battery drain.
My problem: when I use an external power source (a bench technician's 12v
Power supply) everything works great! When I hook up to my AS blue (+) and white (-) everything works on the radio (even the remote) except
no audio from any speaker.
I do not have chassis grounded (although I've tried it)...The radio's black wire is connected to AS white (Grd); radio's constant power(memory) and ACC power is hooked up to AS blue wire (12V). Both of these 'AS' wires supplied previous' radio power.
Old technician is stumped!
