Hi,
I have been getting my rig setup for overlanding. I have installed a 120AH AGM battery and DCDC in the rear tub to power my fridge, lights and water pump. Since the JL Wrangler has a variable Alternator, the DCDC suggests connecting to an ignition source. I have connected to the Ciga Aux power in the back and I have the fuse in the IGN position so it is only getting power when the ignition is on. The DCDC works fine and goes into the right modes etc. The problem is my ESS (Start/Stop) no longer works and the dash show ESS not ready Battery Charging. If I disconnect the IGN source (pull the fuse) this problem goes away. I have fully charged the main battery, Aux battery and the new one. So the DCDC is showing that it is in float mode (fully charged). With the ignition override attached and powered the dcdc will start charging the battery at 12.2v and stop once if the voltage drops below 11.6v. Without the IGN source it is 13.2v start and 12.6v stop.
Any ideas on why this affects the ESS?
Given the variable voltage alternator have others achieved enough charge without the IGN override?
