2022 Mojave, Gas, for several months now been showing 'auto stop/start not available' and a few weeks ago started to occasionally get the 'aux switches not available' for a minute or so after starting.
I decided to go ahead and do the aux delete knowing I'd probably need to go ahead and replace my main battery.
I first removed the wrong cable, no power. Put it back on and unhooked the other negative cable and removed fuse 42. I did not remove the IBS unit, I simply put the neg cable on top of it and tightened the nut.
Whole process took less than 5 minutes. Everything turns on, seems different somehow but it's all on, but only a soft click when trying to start. Hooked it all back up again and everything is like normal and starts fine.
Questions are; should I have removed the IBS and let it set for a while before continuing with the delete?
Am I getting a good enough connection on the negative side; the ground connector is a bigger hole than the post on top of the IBS and I know, at least on tractors and mowers, that sometimes even a slightly bad connection can keep you from starting even though you have power.
I haven't replaced the main battery yet, could it be so bad that it keeps it from starting? While driving it generally reads 14.2-14.4 volts.
What could I have missed or is happening to prevent it from starting.
Thanks!

The 'not available' messages are the warning signs that the batteries need replaced. The Main Battery is in worse shape, and the Aux Battery is what kept you going. Replace the Main Battery, and replace or disconnect the Aux Battery.

Update to this for anyone having the same issue. Main battery continued working but I noticed slower starts. I replaced the main battery, pulled fuse 42, disconnected the aux battery and it started right up. Waiting on some display functions to return since it was unplugged for an hour or so. Main battery was bad, aux probably on its way. Thanks for the help, Mr._Bill.
