| 1. To disconnect a wire from "the minus" plug of the storage battery. |
| 2. To disconnect wires from plugs of the switch of light of the backing located at a back end face of a transmission. |
| 3. To connect an ohmmeter to plugs of the switch and to check up resistance. At neutral position of the lever of a gear change resistance should be equal to infinity (the switch is switched off). |
| 4. To include backing transfer. Resistance should be equal to zero (the switch is included). If at least one of these conditions is not carried out, the switch is faulty also it it is necessary to replace. |
