What happens when you disconnect the HFL unit?

The relay will shut off thus the unit will not draw 1.42 amps from the battery. Do this even if you put in a new HFL unit since the HFL unit will cook if it stays on. To prevent cooking you can put on a trickle charger all the time the vehicle is in the garage.
