Denny,
Since there is no accessory position on a 1950 Chevrolet trucks ignition switch.
How do you have the accessory wire, wired on the 12v Sony FM/AM CD player.
Because 12 volts remained applied to the accessory wire after switching off the ignition switch, some people were having dead battery issues,
Do you have it:
Wired like
Diagram 1 Or
Wired like
Diagram 2 Or none of the above.
Higher wattage Radio/CD players normally do not fully shut down by turning off the Radio/CD players main on,off switch.
12 volts also has to be removed from the accessory wire to fully shut it down.
If you have 12 volts applied to the accessory wire at all times and your having no dead battery issues.
A. The Sony Radio/CD player accessory wire may function differently.
B. You start the truck daily.
C. You have a really good battery.
Thanks,
