ESS Battery Cable Change

[Go Hogs!]

Take a look at the first post in this thread. Some time in 2021 they changed the two ground cables, that is what requires these adapters.

I know about the change but I have seen people with ‘22 models just bolt down the larger connector to the smaller terminal without doing anything and it works.

Here is a link to a guy with a 22 model that just bolts it down tight without any modification.

Aux Battery Bypass

Sorry, yes you can do that as long as you’re not also trying to connect a winch ground.

I have a 2021 (new style). Can I move the winch ground to one of the body ground connection points, so I don't need the non-stock looking connectors? (Jeep is still under warranty, I don't want to give them any excuses).

Thanks.

I don't know for certain but I wouldn’t try it. The winch pulls a lot of current and you’d be relying on all of the connections between wherever you connect and the battery to be sufficient.

My dash yellow service start/stop warning light popped on. I’ve been searching this site and YouTube to find a way to remedy this problem. Here is what I think might work, but I’m not sure?? See pictures.
1. Remove fuse 42 from fuse box.
2. Disconnect the aux cable from battery.
3. Unplug the left plunger under hood.
Thanks.

Yes, remove fuse F42 and then disconnect the Aux battery negative cable from the Main's neg side. Do NOT fool with the plunger. Leave the 2 plungers alone!

IF your Main is iffy, you will still see the Evic warning.

Thanks for the reply. If I unplug the plunger wouldn’t that deactivate the start/stop which would lessen the burden on the main battery?
