Hi everyone,
Recently got a used 2010 chevy silverado 1500 as a company vehicle. I noticed immediately that the radio(aftermarket) turns off when you start to drive off. It only works when you are engine off in accessory mode or sitting idle in park/neutral. I pulled out the radio and saw that it was manually wired in.. So I did a little research on the vehicle wiring harness and wiring harness adapters to ''kind of'' understand what the colored wires mean. I then tested the wires in all positions from engine off, to key in accessory position and engine on in idle etc.. Everything tested 12v. Battery test was good, Tested alternator by taking off the positive cable and it was good from what I was told. Only time the radio works while driving is when I rig the constant 12v wire to where I have to manually turn the radio on and off for when I want to use it. So I tested the accessory/ignition wire as I proceeded to drive off and the voltage dropped sporadically and would not stay at a stable voltage. Does this mean there is a short on that wire somewhere? or possibly a part that needs to be changed out?
