I have a 7245 controller that were run about 10 min. and then shut down. Checked all cabling no loose connections. When the unit shuts down voltage is still there just no amperage. I thought it would be a throttle problem replaced the throttle still the same. This morning I put the car on jack stands and let it run until it failed was only drawing about 20-25 A no overheat in any of the wire then I swapped out throttle boxes still the same, try to zero to 5K pot instead, no difference. But I do find that when the unit is in its fail mode and turned on if I disconnect the throttle it will ramp up to full speed plug throttle back in, back to zero and no response. Any help from you guys would be greatly appreciated
