New HU = Dead Battery

[ranahan@charter.net (John Erickson)]

I appear to have committed a fatal error with the 
installation of my new head unit.  I tied the “Battery” 
and “Accessory” leads on the HU together and hooked them 
to a single always-hot power source in the car.  I let the 
car sit for a couple days and the battery is almost dead. 
 I guess I’ll take the “Accessory” lead and hook it to a 
switched 12v source.  We don’t really have an “Accessory” 
position on the ignition switch, do we?  If so, is 
anything connected to it?
