I have my truck grounded on the front chasis to a 8 foot copper ground rod when the truck is stationary in the drive. I also have a ground chain on the rear bumper. I have had people stop me on the street just to let me know that I am dragging a chain. This is what fuel trucks use to use to prevent static discharge. I have heard that this will protect or reduce emp. Is this correct?
