Fig. 9.2. An arrangement of the switch of lanterns of a backing above картера transmissions
The switch of lanterns of a backing is located above картера
transmissions (fig. 9.2
Include ignition and include backing transfer, thus the switch should include backing lanterns.
If backing lanterns have not lighted up, check up serviceability of a safety lock in an electric chain of lanterns of a backing.
If the safety lock is serviceable, disconnect an electric socket from the switch and an ohmmeter check up a condition of its contacts which by the included transfer of a backing should be closed (resistance equally 0). Establish the gear change lever in neutral position, thus switch contacts should be opened and the ohmmeter should show infinitely big resistance (absence of conductivity). In case of malfunction replace the switch.
If the switch is serviceable, check up a condition of an electric chain between a safety lock and the switch. If the electric chain is serviceable, probably, have fused lamps in backing lanterns.
If lamps in backing lanterns are serviceable, check up a wire connecting the switch with lamps.
Disconnect an electric socket from the switch of lanterns of a backing.
Turn out the switch from картера transmissions.
Before installation check up the new switch. Connect to contacts of the switch an ohmmeter and be convinced that at pressed плунжере the switch contacts are closed, and at released — are opened.
Screw the switch in картер transmissions and tighten its demanded moment.
Connect to the switch an electric socket.
Check up work of lanterns of a backing.
