Hi. New to this forum. Working on my first jeep a 2016 Wrangler JK.
I replaced the starter motor and the battery, and now have a 1.9A parasitic drain. New battery drains in a day or two. Probably I kinked a cable, but I want to make sure I didn't overlook anything before I start tracing the power cables.

To diagnose I have done the following (separately, not all at once)
1) Disconnected all aftermarket lights and cameras
2) Disconnected the new starter motor (both cables)
3) Disconnected the alternator (both cables)
4) Removed and checked every fuse in the TIPM
5) Swapped every relay in the TIPM
6) Disconnected the TIPM power cable (no other cables)

None of these lowered the 1.9 Amp drain.

Are there any other tests I could do? Anything I overlooked?

Thank you
 
Assuming the 1.9A draw is accurate, that's ~24 watts of power. This is a common output for most dual-power USB-A/C type chargers in the automotive world. Do you happen to have one plugged in somewhere?
