Hey folks.
I’ve just got done installing a second battery + wiring in the Jeep. I was trying to research this before buying the gear but couldn’t get a definite answer so I figured I’d just rig it up and look for any problems.
The setup I’m using is just the kit from 4wdsupacentre which is basically a VSR that cuts in when the main batt is charged over a certain voltage. According to the indicator led on the VSR it is sending charge to the backup batt, however when I check it with my multimeter, the backup batt is only reading 12.85v with the engine running.. My understanding is when the charging is actually running it should be reading somewhere around the 14 mark. Do I just need to charge it a bit longer? Or should it be reading higher while the engine is running?
Do JKs have one of the shitty alternators they warned me about that don’t generate enough juice to charge 2 batteries?
Edit: I chucked the multi on the main battery and it’s reading 14.x volt so it’s at full pretty much.
