2001 chev s10 pick-up 4.3l battery goes dead over night. I check the draw with a test light, and started pulling fuses. The light goes out when I take the 15amp out that is on with int bat. The radio goes out and the dash lights to with that fuse. Also there is a 50amp under the hood to, and the same thing happens when you pull it out. Also I pulled the radio out to see if that had draw. When I unplug the radio the test light started to blink, when I plug it in it stopped but the light was still on. Can you help me. Thank-you. Also I have check the charging 14.0volts and load test to.

Suspect diode failure in ALT unplug ALT see if draw goes away. Or feel alt see if it is warm long after engine off. Do you have a DVOM?
