The motor should be at ground potential! Pull the screw for the pickup. This could be a challenge, as you usually need to disassemble the truck to get there. The screws in the truck are not the easiest to get to. It usually takes a small Phillips head screwdriver into the slots in the frame coming down from the top. Sometimes the pick up is mounted with the screw that also holds the motor to the truck. Go carefully here, so you can put things back to gether! Don't ask how I know this... Anyway, with the pickup off, tape the ends of the leads to the truck so they don't short anywhere. Leave the leads to the motor connected. Put things back together w/o the pickup, but with the leads taped. Run it. See if you still have sparks. (Nice picture of the sparks, BTW!) If you don't, the problem is in the way the pickup is assembled.
