Greetings guys,
first discussion I start, yes I've searched and read tons on here before posting.
Jeep JLU Sahara 3.6 2018 with 10000 miles. Basic warranty ended in May 2021.
In early 2019, my ESS stopped working and I constantly had the ''ESS battery charging'' message. Dealer replaced both batteries and all was well until Covid arrived and Jeep stayed parked a lot.
Last spring (2021) I noticed that the ESS wasn't working again and I had the same ''Battery charging message''. So I took numerous Country road trips with all electricals off, hoping the ESS would charge, but it never worked again.
So early this week, I decided to check to see if I could find what is wrong and got online to find a few conversations on this here forum regarding ESS and hard PDC fuses and even watched a video with Brandon Haneline about the subject.
First thing I noticed, was that N2 and N3 cables were reversed (the numbers are engraved on the end of the cables). It went ( N1-N3-N2-N4......) So I thought to myself that's it!!!, those idiots didn't bother connecting things right.... (After all, these are the same guys that put 7.5 quarts of oil last oil change and ''fixed my back glass so poorly that it exploded when I tried to use the defrost for the first time and then denied it was their fault) so I'm gonna correct that myself.
So I followed David Haneline's video to the T, disconnected both negatives and even wrapped them up separately to avoid any troubles and proceeded with switching N2 and N3 to put them in numerical order like they should be.
PROBLEM (or is it a problem?): When I reconnected the negatives to the main battery post, I experienced sparks and heard a few clicking sounds like a solenoid would make. While it worried me, cause on David's video, there were no such sparks, I continued to put things back together and went for a ride.
OBSERVATION: While all I previously had was the ''Ess not ready battery charging'' message, I suddenly had proper information (or maybe I had them before but never noticed them)... ''ESS not ready, transmission not in a forward gear'' or something like that, then ''ESS not ready, engine not warm enough'' and then '' ESS in Battery protection mode'' what does ''PROTECTION MODE'' mean??? this I never saw before I am certain.
So I messaged David Haneline with the information above and all he replied was that I blew a 100amp fuse in the PDC.
-Is that a fact ???
-Anyway to test that ???
-Which fuse are we talking about ???
-Is it something that is urgent to replace???
-Will I end-up stranded if I don't fix this now ??? ( I have a 2 hour trip to take this coming week-end...)
-If I blew a fuse merely by reconnecting the negative posts, will it blow again when I reconnect the battery after replacing the whole PDC unit??
- Any possibility that the dealer purposely switched the cables as part of the fix when they replaced both batteries, like a TSB or something ???
Everything else seems to work perfectly except for ESS. I have a multi-meter but not sure where and how to check if the fuses are good
Lots of questions I know,
Thanks for any help,
Steph
