resolved - Low voltage after winch install - electrical issues continue - help please

[its_ok]

Hi everyone,

I just installed a Warn solenoid so that I can control my winch power from aux 4. Upon finishing my install, I noticed that my vehicle said auto start stop disabled, and that the vehicle will shut off soon.

Voltage on the battery within the dash says 10 volts and dropping. The actual main battery is showing 12.6 volts.

It’s almost like my vehicle isn’t running off the alternator at all.

Any suggestions? I have a 2024 and am trying to figure out how to disconnect the aux battery but it seems like my cables are different than the pictures I'm seeing on the forum.

Is it possible that I blew a fuse? I didn't have any issues with start stop or this voltage problem prior to this install today.

UPDATE: Car starts, and engine sounds like it is misfiring and it revved up to a higher RPM on it's own, so I shut it off right away. I think this is probably related to the low voltage... I hope I didn't kill my Jeep (maybe I didn't disconnect something properly when installing the solenoid and I blew the Z Case Fuse Array?). Going to have it towed to the dealer in the morning unless I find a solution tonight.

UPDATE #2: I tested voltage with a multimeter on fuse n2 and see a little over 12 volts. N5, N6 show a little over 12 volts. N3 and N1 show 7.1ish volts. I think those fuses (n3 and n1) are blown?

UPDATE #3: FYI for anyone reading this - make sure that you disconnect your main and aux batteries fully otherwise what happened to me may happen to you. I had to swap my fuse array as N3 was blown. All is well now after swapping in 68368854AA that I bought from my dealer (I have the tow package, so that part works for my Gladiator).

UPDATE #4: I'm unsure if there's lasting damage from when fuse N3 blew. I'm having a couple of electrical gremlins - issue with Start Stop showing as not ready, potential burnt cable? - not sure if it's normal to have an amber/yellow substance on the terminals for some of the cables. I'm hoping this is safe and normal.

UPDATE #5: cables look normal per other pics I found online .

I want to note that I disconnected the solenoid. That’s what the red cable is dangling above.

Update: Solved. Sharing this info just in case this helps anyone else. After reading about this on the JL forum - ESS Battery Cable Caution and ESS (N3) Fuse Warning | Jeep Wrangler Forums (JL / JLU) -- Rubicon, 4xe, 392, Sahara, Sport - JLwranglerforums.com, I got this solved.

I think what happened was that I wasn't careful when installing my solenoid, and I must have blown fuse N3. First time working on a vehicle with a dual battery system...

I swapped the cable going into N3 to N4, and all is well now. Now to figure out what fuse array to order so that I can get this back to how it was originally.

He'll tell you exactly what you need, cost and so on.

Where did you connect the winch ground? Just curious, as I don't see it in the picture..........

Thank you for sharing the forum sponsor info. I swung by the dealer today and bought the replacement 68368854AA part and swapped it in and all is well now.

In that picture, I had the winch ground disconnected. I have it hooked up to the negative terminal of the battery.

Makes sense you had it fully disconnected to check things out.

Top connection/threaded post on top of the IBS (the device on the negative terminal) is best.

Thank you for your suggestion!

I just took a look at my fuses again to make sure that everything look OK after my re-install of the fuse array, and I noticed that my cables have like what looks like yellow/orangish glue around the bend where the cable connects to the fuse array.

Image included and red areas of potential concern are noted.

Is this potentially damage from when I blew fuse N3 out of my carelessness? Can I drive safely like this? I'm going to take it to a local Jeep shop this Wednesday to have it checked but I am curious if anyone else has already experienced this. I'll document what is communicated to me.

I also noticed that I have code p0562 - which has to do with battery/system voltage being low. I tried clearing it with my code reader, but it does not go away. I also noticed that my Electronic Start/Stop system menu page on the dash says "Start Stop Not Ready" and nothing else - no message about battery charging, etc. It does not appear to work either.

Never mind - found pics online from others that have that same orange colored goop on the cables. Looks totally normal.

May be from the sealer in the insulating tubes over the terminals?
I use marine or water proof heat shrink tubing that has a clear "glue" inside that looks similar but not orange.
