does leaving the key in the accessory position drain the battery? i have found my battery discharged after leaving the key in the accessory position
for a couple of days.

thanks.

that will be running battery power to the stereo, which will use a little power even when the stereo itself is off... so, yes

which means it drains power when the accessory is OFF too..

because the radio has constant power to keep it's memory.

if the radio is off it's not what's draining your battery. it's all the ACC relays that are ON that's doing it.
