Hi it doesn't have an ev 100 control card, it's very old, has a fwd contactor, rev contactor and hydraulics contactor, all working, then a pcb and black box where all the terminals are gathered (i assume this is the scr?)and a few fuses. I've removed the battery and connected whilst it's at the side of the truck, the chassis is live with the ignition on? 72v and the motor moves slowly with the wheels raised( no load) and the speed increases with pedal travel. I'm so confused.
