Also, my radio randomly changed stations on its own a day before this all happened...could my ICM cause any of this?
The upper picture shows the meter selected for small battery testing, but seems to be showing DCV. The dial should be turned to DCV, if you are trying for that. The way it is connected could result in the meter popping a fuse, or frying the meter if the headlights or starter were engaged, as the meter is in series with the battery and the load.. To simply measure battery voltage, touch the red lead to the positive terminal and the black lead to negative when DCV is selected and the leads are in the appropriate sockets. There may be a difference in the readings using the other modes.Alright here's an update. Tested the car again today and now I'm baffled. I did this twice too. Reconnected the battery, let the car warm up and shut her off. Opened up the hood, trunk and driver door and closed the latches and the car went to sleep. Waited 15min, then carefully hooked up my meter and slid the ground off the battery. Read .002A. I may buy another meter... I then proceeded to pull every single fuse and relay in the trunk, driver's panel, and under the hood. No changes at all. I did that twice. So now I've got a random draw that is sneaky. I decided to investigate around the scm area, looks like someone may have been in there before. I didn't pull the tire but the rivets on the wheel well were drilled out. If they replaced the scm I'd have my alarm sound back correct? I also did some testing on my alternator which was interesting. Not sure if this is normal:
Alt charge cold idle 14.38-14.49
14.40ish warmed up at idle, max and min readings were 14.1 jumped to 15 (voltage went down to 14.1 then jumped to 15 and then evened out around 14.4 again). I tried to do that ACV test and here's what I got: ACV . ~.02-.03 bouncing and occasional jump to .1v don't know if that indicates anything about my alternator diodes. Anybody got a guess or a direction to go next? Posted some pics, that's my wife's hands FYI definitely not mine 😂 also if I'm using my meter wrong please roast me View attachment 134946 View attachment 134947
