WARNING: Electrical failure (short circuit) may cause electrical ignition and fire.
If any circuit of electrical equipment fails, first of all check if the fuse protecting it has blown, referring to the table. 10.1 and 10.2 (see «Location of fuses, fuse links and their replacement»).
Replace defective fuse. Repeated blown of the same fuse serves as a signal for immediate repair of the corresponding circuit of electrical equipment (see «Diagnostics of malfunctions of onboard electrical equipment»).
WARNING: Never replace a blown fuse with a larger fuse or «bug».
