Had a very dead battery on a 2018 Equinox. The vehicle owners manual is VERY specific stating to use the remote ground connection to jump or charge the battery.
IMO, that is due to exreme concern over H2 gas explosion or potential fire. Been jumping cars for over 50 years and never had a problem yet, but that is another issue.
Follwing the manual’s instruction and was unable to either jump the vehicle or charge the battery. Called AAA and they sent a tow truck to provide roadside service. He had a portable jump box.
After I cautioned him to use the remote ground, he connected using the remote ground and vehicle would NOT start. Out of frustration I requested he then jumper directly to the battery and not the remote ground. Car started quickly.
Took vehicle to auto service and got the battery replaced.
I have two questions.
1. Why would jumping using remote ground not work and jumping to battery does.
2. Why in heck does the owners manual give instructions that do NOT work?
