Schematic diagram of the control system switch
Checking the technical condition of the switch
1. Disconnect the switch and remove it from the panel.
2. Apply battery voltage to pins 4 «-» and 5 «+». (VB battery voltage).
3. Measure the voltage between pins 3 and 4.
4. Compare Percentages (V/VB * 100 measured voltage/battery voltage) with the values below.
5. If voltage is not within specification, replace switch.
