Question about 1993 Jeep Grand Cherokee
When installed radio has no power ive checked the fuses and tested the radio
Got a voltmeter,
make sure the ground wire is 0volts , key on, radio on.
then make sure all 12vdc power wires, on radio have 12vdc.
some have 3.lines. (and a 12v out to antenna motor (skip that)
radio power, memory, and dial lamp.
the radio power must be hot. or radio will be DEAD.
it's that simple , any DMM even the dirt cheap one at walfart does this.
the meter will never lie to you, and can also check your bad fuses.
0 ohms good'
infinity ohms bad fuse.
