Okay I've had a bad problem on my 63 with battery drain ever since I can remember . If I dont put it on the battery charger for 2 weeks itll be dead. Any ideas or what to check? You can turn the radio on without the keys in the ignition, is that normal? It has an alarm but isnt set when in the garage . Would a bad voltage regulator do this ? I dont know if its the original one but I know I havent changed it in the 20 years I've owned it.

Radios are typically wired to require the ignition to be in either the "on" or "accessory" positions to operate.
Does your radio have a clock by chance or an electronic station memory function? These will draw a small amount of power with the ignition switch in the "off" position.
If you have a good volt meter you can check across the battery terminals while removing circuit fuses to see if the voltage increases. That will at least isolate which circuit is causing the drain.
My money is on the alarm causing trouble.

I just had the same problem with my home generator. It was a bad diode in the alternator.

Hmmm so do I need to turn the key to "lock" instead of "off"

It's not normal to play the radio with out the key on.
If it will go 2 weeks with out charging, it's probably not the regulator. A regulator will usually run it down overnight.
Just because an alarm system isn't armed, doesn't mean it not drawing some current.
It could also be the condition of the battery, not holding a charge. Will the battery run down if you leave it disconnected for over 2 weeks?

Just got my volt meter in today so will use it this weekend . Also I dont have a glove box light. I'm betting it's either the radio or alarm that's draining the battery . I know there's no wire from the radio to the battery..
Not sure how its hooked up.

Disconnect negative battery cable put a test light between the battery and negative cable. Start pulling fuses one at a time when your light goes out you found the circuit causing your drain. A bad horn relay is another common culprit. If your horns are disconnected you might not know the relay is bad, if it is not totally shorted try touching it but be careful sometimes that relay is HOT.
If that doesn't solve it then put the signed title in the glove box and send it over to my house and I will take care of it for you.

Funny thing I have opened hundreds of glove boxes and the ONE thing I have NEVER found in one is a pair of gloves.

That is because the ladies that own the gloves, take them with them when they get out of the car.

My 64 SS I turn the key all the way to the left then back one click to take the key out. If I don't it drains the battery.

Sounds like it's time for a new ignition switch.

All the way to the left on factory ignition switches is accessories.

One click to the right is were the key is to be removed (for all 61 to 64’s )

I thought you meant you HAD to turn it to accessory first before turning it to off in order to keep the battery from draining.

Andy is just saying he can pull his key out while in the accessory position and that will drain the battery. Sounds like the power wire on the original poster’s radio is connected to a battery fed circuit. Taking off the negative cable and placing the test light in between the negative terminal and negative wire will immediately show if there is a draw on the battery (make sure the doors are closed or the dome light switch is depressed or disconnected). Then pull fuses til the light goes out and that tells you which circuit that is draining the battery. If the light stays on with all fuses pulled then it is something with a direct line to the battery and doesn’t run through the fuse box.

Recently ? Maybe 2 years by now went through a similar issue.
These types of issues are not fun to find but are educational!
Great you have a new volt meter, that will help.
The idea of pulling fuses is a good idea.
You need the wiring diagram, I too tested what ever was using 12 volts with ignition off.
That is what you are looking for.
The wiring diagram will help you find those items.
Sure the issue with your radio needs addressing, but what is draining the battery?
your newer car on the driveway can sit there for months with out drawing the battery so why can't this car?
Find what all is powered with the key off, wiring diagram will show this, I worked from the diagram, testing the lights, cig lighter, dome light, found the horns were dead short.
Time and testing will reveal the issue, learning what is connected, what is this or that is good to know.
Work from your wiring diagram, my case the short was so bad I could not connect the battery due to current draw, yet may trusty volt meter using in the continuity mode eventually help me find those horns, then what ever it is you find you ask why did that all of a sudden go bad?
I won't go into what all I pulled to find the issue, but the wiring diagram and your trusty volt meter will help you find it.

Well I just saw that they have the radio red wire plugged into the "batt" spot on the fuse box... with it plugged in and unplugged my volt meter reads 12.50 . Where is the radio supposed to be wired into ?

There should be a fuse marked "radio" in the fuse block. Check the wiring diagram for the wire color. In 62 the wire was 16 ga. Yellow.

I don't see that . But they had it plugged into the bat part . Now I'm trying to figure out how to get it wired into the acc plug on the ignition switch. . It wont let me subscribe to this topic either for some reason and that's annoying

This procedure and the American autowire link will definitely help you find the problem circuit

Okay I just tried the test light method. It comes on bright and then immediately just fades out and stays off...

The acc terminal is marked on the back of the ignition switch.

Did you get a wiring diagram?

Did you try disconnecting the radio and the alarm to see if the battery still dies in 2 weeks, or did I miss that?

Yeah I took the ignition switch out and it had these wires going into the plug into the back of the switch. . Would I have to just splice the radio wire into the wire going to the ACC wire ?and I did disconnect the radio for 2 weeks and it slowly drained from 12.50 to 12.35.
