Well, I opened up the steering column and got re-educated on the internal design. I need to correct my previous statement. I replaced the lock cylinder 2-3 yrs. ago, not the ignition switch. I removed the actual ignition switch and found out it was very worn out. I took another out of a parts car and installed it. As soon as I get the dash components back together, I'll find out if that corrects the voltage to the radio. Also, checked the dash "ground" bolt under the dash on the pass. side and it needed serious cleaning.
