Parasitic Draw from radio

Hi guys hope you're all doing well.

Battery kept dying all randomly and couldn't figure the parasitic draw until i took it in and it got located to the interior light/ radio fuze.

Is there any way i can terminate direct feed from battery to radio without losing my interior lights?

Are the door switches also part of this system? Just wondering if one is faulty and allowing partial voltage to flow to the courtesy lights.

Actually thats a good point the actuating pins don't activate the light... or at least the front lights. However i use a Mud interior that i manually switch so shouldn't that keep the circuit closed? I'm on IG: https://www.instagram.com/osloblue42/

Well if the mud light is off until you physically turn it on that shouldn't draw any power. The door switches should be all open when the doors are shut and so no power drain either.

What is the back light doing?

Pull the bulbs from the interior lights and see if the power drain ceases. Then the stereo power. It is the only way to find the drain.

No i don't think its the interior light, but the radio off the same fuze. I'm on IG: https://www.instagram.com/osloblue42/
