A vsr is a voltage sensing relay. It works by way of connecting the starter battery to a high amperage relay, and then to the enjoyment battery(‘s) with a heavy duty battery cable (length of cable depends on how lengthy the cable is and what number of amps are going via it). A vsr is then linked to the excessive amperage relay. The vsr senses when the vehicle is running and opens the connection at the excessive amperage relay to allow the amusement battery(‘s) to be charged. When the engine is switched off the vsr senses the voltage drop and switches the excessive amperage relay off. This stops the engine battery from being flattened through the leisure batteries. That is called a cut up price device.
