Yamaha G19 Wiring help please!

[gator1873]

I purchased an old 2002 g19 golf cart, it had no batteries, so I purchased some batteries, put them in the cart, but the wiring in this cart is crazy, looks like some of the black wires are positive???

Can anyone point me in the right direction of a video or helpful info

thanks,
Gator

Do you have lights and a blue aluminum dc/dc convertor? No extra wires should be on the main pack positive or negative posts if factory lights are not present except for a charger negative wire (charger positive is at solenoid). These extra wires are not going to be on a factory wiring diagram because they were added by someone else. Hate to say it, but you are at the mercy of whom ever added that stuff. Usually those extra wires use two batteries to power add-ons like lights.
