1.9A parasitic drain. Any tests I missed?
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.
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
None of these lowered the 1.9 Amp drain.
Are there any other tests I could do before I start tracing the cables looking for damage?
Thank you

Did you track down the issue. I notice at times my radio goes out. If I disconnect the battery for a while and then reconnect it, the radio usually comes back on. Then after a few days it will be without power again. If I don't drive the Jeep for about three days it will not have enough charge to crank. The battery has been tested.
