I'm using a variable output regulated power supply. It has voltage and amperage meters.
Your comment about the correct polarity made me check my connections and I'm embarassed to say I had my positive and negative connections at my power supply reversed. When hooked up properly, the 12V6 lights with both the vibrator and the OZ4 installed and the radio now plays. Thank you very much.
The volumn is very low with a car antenna hooked up. Do you think I've damaged some component ?
The voltage drops on my power supply when I put a load on it. I normally readjust to required voltage. Any problem with that ?
