I'm a sick beastly man who pees.
what the first guy said. you door lock actuator has taken a crap. replace it.
A mast is a support for things we want to be higher than the rest of the structure, e.g. mast of a boat, mast for the flag (flag pole) Cheapest and strongest material is steel. Attach the lightning rod to the mast, run the ground wire from the rod to the ground bar and you have lightning protection.
