Onboard electric equipment The elementary diagnostic equipment and examples of its application How to make a lamp sampler Lamp sampler of nakalny type At service of systems of electric equipment the lamp sampler is the most effective tool for stock-taking of conductivity of the contour which was under loading. The elementary lamp sampler can be made of pair of pieces of a 4-millimetric wire, pair of clips of the crocodile type and the boss equipped with two contacts and 1-нитевой a lamp calculated on supply voltage in 12 In with a 2-contact socle (see an accompanying illustration).
Lamp sampler on a light-emitting diode Use of a lamp sampler of usual type (with a filament) for conductivity stock-taking in the chains including in the structure electronic components can lead to an exit of such components out of operation owing to course through them rather high current. Originators of this Management recommend to use in such cases a lamp sampler on the basis of a light-emitting diode (LED). The elementary lamp sampler on a light-emitting diode can be made of a piece of a 3-millimetric wire of suitable length, a clip of the crocodile type, a light-emitting diode and the resistor of 1/4 W, 560 Ohm. Besides the casing which is rather simple for making of an old ball pen and a thin metal core (a wire piece), pointed from one end is required. Track, that connection of the anode and the cathode of a light-emitting diode was made in accuracy as is shown in an illustration.
How to make a wire crossing point At diagnostics of malfunctions of components of systems of electric equipment it is very useful it appears to have near at hand a wire crossing point.
Check of serviceability of switches If there are doubts in serviceability of functioning of the switch, disconnect from it electroconducting and by means of a lamp sampler check it on food existence. If the switch is switched on in an ignition contour, for check it is necessary to turn a key in the situation ON. Having defined color and location of a power wire disconnect from it a lamp sampler, take a suitable wire crossing point and connect it between a power wire of the switch and a wire from its opposite side. If a contour as it should be, it is necessary to replace the switch. Check of serviceability of lamps At suspicion on refusal of a lamp take it from the boss, then connect one end of a small wire crossing point to the positive plug of the serviceable battery, and its second end - to a uvula on a wall of a socle of a lamp. One end of the second wire crossing point connect to the negative plug of the battery, the second press to lamp contact. The serviceable lamp should light up. If the lamp is equipped with two filaments, press the wire crossing point end to the second contact of a lamp. The lamp also should light up. It is necessary to replace a faulty lamp adequate to it on power consumption and rated voltage of a food. Check of serviceability of an electric chain If there are suspicions on refusal of an electric contour, submit on it tension, having turned on the corresponding toggle-switches and switches. Disunite any of plugs of a contour and connect one of lamp sampler wires to power, or the party of the disconnected chain turned to the switch. The second wire of a lamp sampler connect to mass of the car (to any screw or a bolt on the chassis, a body or the engine block). If the lamp does not burn, check a contour closer to the power supply or the switch. If the lamp lights up, continue to carry out check, moving ahead towards the consumer of the electric power (the motor, a lamp, etc.).
