Ok so there is this mysterious spark coming from my balancer to my block. Checked the rpm gauge and moved it off and pulled all the battery cables off and it still sparked I cleaned all the cables and still more spark. It has to be static but I don't no wat to do help please. Thanks.

 

Try unplugging the speed sensor and see if that stops it, maybe it's cracked or somthing

 

I unplugged All power from the batteries from the truck and it still did it.
