Hey guys,

So I realized a week back that all of my position 1 12v accessories stay on even when the key is on the off position and removed. I first noticed it when my radio was staying on which drained my battery.


I posted about this once before and it was discussed as possible that my ignition switch was bad. So I've replaced my ignition switch and the problem persist.

I removed the plug from the ignition switch and the issuer persist. Which would mean it was something downrange from the ignition switch, right?

What is between the engine bay and the ignition switch plug that would control the key on accessories for only key position 1 staying on? I verified it was not just the radio by testing the switched power wire on a volt meter. Still getting power no matter if key is in or out.

What else could it be?

Thanks!
