Hey guys, I have a curtis 1236 controller and i want to use the in internal precharge. I have my main contactor connected to the ksi coil return pin (pin13) and the driver 1 pin (pin6). The main contactor is between B+ and battery positive. MY pack is 48V. It seems as if the two pins im connected to only ever have 48V on them and never changes. Even when i set hold in voltage to 50% the two lines still have 48V and nothing is precharging and i get the main contactor short or open fault. I think my wiring may be wrong and im hoping if anyone can draw me a diagram or send a picture of what the corect arrangment is. Any help would be appreciated.
