1. Remove the corresponding switch.
2. Usual switches have only two joinings. In this case on one of contacts always there should be a pressure (+), and after deenergizing as well on the second. There are switches with several contacts. It is necessary to find out from such switches under the scheme where pressure moves. If necessary it is possible to include ignition.
3. By means of a control lamp check up, whether there is a pressure on the target plug. If pressure is, the switch is serviceable.
4. If on the entrance plug of pressure is not present, there is a breakage in a food cable. By means of the electroscheme it is necessary to check up a wire of pressure and if necessary to replace a wire. |
