Troubleshooting in electrical equipment

When troubleshooting electrical equipment, it is important to act systematically. This applies to both checking burned-out incandescent lamps and idle electric motors.

The first step is to check the fuse that protects this instrument. The set of fuses is marked on the cover of the fuse box.

Replace the defective fuse and turn on the power consumer to check if it blows again. If it burns out, then you need to find and fix the problem. As a rule, this is a short circuit, that is, somewhere in the circuit or in the device, the ground is connected to the plus.

The second step: if with a good fuse, the incandescent lamp does not light or the electric motor does not work, it is necessary to check the current supply.
