Parasitic power draw on Jeep JK Wrangler

What others said is true, 1 amp draw would be same whether in series neg. or pos. lead.
I'd do this simple thing, since 1 amp draw even after pulling all fuses...
5) disconnect meter
6) disconnect large cable at starter motor which goes to battery
7) reconnect meter: If no current draw replace starter

Or clean connections on starter cables, and see if 1 amp draw is gone - very common on Jeeps.

If he disconnects starter cable and 1 amp draw, try cleaning...see if draw disappears

Had the battery load tested - passed no issues.
Blew the fuse on my meter so now I have to wait until Saturday for the new fuses then back to testing.....

What happened?
Testing leak current on the positive side and accidentally touched other probe to something grounded?

Plugged the probe into the wrong spot while not thinking - blows the fuse quick once power is added... LOL

meter - 1.jpeg
Went and disconnected ALL accessories - and you can see the meter reading - bounces up and down a 1/10 but this is where I am at. Thinking now it is in the Jeeps electrical system for sure and not my add ons. I also disconnected the alternator and no change. Didn't have time to disconnect the starter yet- will do that, clean everything and see if I still have an issue. If so thinking it maybe time to drop it at the dealer. I have. lifetime warranty on the Jeep with a $50 deductible so if something is wrong they can do it and Im not out anything but $50. Plus there is two recalls that need done so get it all knocked out at once.
Anyone have any other ideas Im missing?

Sort of what I thought once I figured out it wasn't anything I added!

Good idea you have about taking it to dealer under warranty. I don't have anything useful , but since everyone else always has something to say on electrical questions I figured I should to.:D

Do you get the same exact VOLTAGE from the disconnected battery cable to the disconnected battery post, as you do across both battery posts?
You should, except for very unique circumstances. Test results will eliminate or confirm circumstances.
