Warning: Electrical fault (short circuit) may cause electrical wiring to ignite and even cause a fire.
If any circuit of electrical equipment fails, first of all check if the fuse protecting it has blown, based on the data given in Table. 10.1 and 10.2 (see «Mounting blocks»). Replace defective fuse. Repeated blowing of the same fuse serves as a signal for immediate repair of the corresponding circuit of electrical equipment.
Warning: Never replace a blown fuse with a larger one «denomination», or «bug».
To make troubleshooting easier, use electrical equipment diagrams.
