I thought I had finished my EV truck only to find out that I have several problems. So I think I want to solve the problem with ELCON PFC 3000 charger first . When I plug in the charger which I installed as an on board charger the LED blinks a few times and then I get a steady red light indicating a full charge. When I check the battery pack with the volt meter it reads 135v a full charge should be 144v+. My battery pack consist of 45 lithium Life Pro4 batteries with a BMS attached to each battery. I drew a diagram and scanned it to my computer but I can't seem to upload it to the site to show you how I wired the charger. So I will try to explain how I did the wiring and hopefully you can see where I went wrong. I will start with the Soliton Jr. controller on the Signal +12v terminal I ran a Brown wire to the L-COM terminal on the MiniBMS control board V3. Then on the Soliton Jr. Inputs 1-2-3 I ran a Blue wire to the L-NC terminal on the MiniBMS control board V3. This is where I think I screwed up on the Soliton Jr.Signal GND terminal I ran a Green wire and at the MiniBMS control board V3 I spliced into the blue with a 5k resistor as the diagram shows that came with the MiniBMS controller. I have never charged the entire battery pack with the ELCON charger always with a smaller charger to level off the battery pack.
