That will only happen _if_there_is_a_SERIOUS_wiring_problem_!!!
Please find and fix it before someone dies.
There should be zero current flow from the block heater to the
block/chassis/body of the car. And the ground wire should cause
the circuit breaker to trip if there is such a current "leak".
This suggest you have two problems.
* The ground wire from the service panel is not getting
connected to the body/chassis/block of the car like it is
supposed to. Is the ground pin on the block heater cord
missing?
* There is contact between one of the current carrying wires and
the body/chassis/block of the car
The only reason you can feel a shock is because of BOTH failures.
Possibly a previous owner had a issue with the block heater
tripping the circuit breaker so the ground was disconnected.
Repeating the second line - this is a potentially life threatening
fault. Please don't ignore it!!
