Blue Positive Brown negative, Yellow with green stripe is additional ground. many people are trying to use the 2904JT charger for a 24 volt charger for other things. I am using mine on an e bike that has 4 12 volt batteries. I charge them 2 at a time and it works well. It only shows voltage when the batteries are partially charged. Some kind of safety feature to keep you from charging a shorted battery. No schematics available, I took my chances and verified the Blue wire is positive. lol Good luck with you project or re wire. : )
Replace the Model-24 battery with a new
