Charging 48v using OBC out the cart

Golfdog

I am looking at bench charging a bank of batteries (48v) using a spare OBC from a Precedent. I have done it previously with a Series OBC by joining the 2 black wires that go to the Controller Negative, and the red wire from the OBC (that went to the solenoid) to Battery Positive. I have the charging recepticle. The Precedent has a 6 pin plug with Light Blue, Purple, White, Yellow, Brown and Red wires. I assume that yellow is solenoid negative, brown is battery indicator light, and red is power. Not sure about the others and whether I need to jump any of them. TKS
