Check of lamps накаливания


1. Remove a lamp and check up it visually. If the lamp incandescent filament has fused or the glass flask unsteadily sits in a socle, a lamp replace.
2. For exact check of serviceability of a lamp it is necessary to do the following:
Attach a lamp directly to the storage battery. Polarity observance in this case is unessential. One wire attach to feeding contact of a lamp, another to the lamp case. If the lamp does not light up, it is necessary to replace it. It is necessary to check up also, whether there are no corrosion traces on the lamp case. In the presence of a rust smooth out its skin.
3. If the lamp is serviceable, insert it into a cartridge and include. If the lamp does not light up, check up a food by a control lamp. For this purpose attach a control lamp to weight. Joining is carried out as follows. One wire of a control lamp joins a weight point on the engine (the smoothed out metal) or is direct to a negative pole of the storage battery. Other end of a control lamp (+) joins or the current carrying tip or is stuck in a current carrying cable. If now the control lamp lights up, and the checked lamp does not burn, there is a breakage in a weight wire to a lamp. For check put a weight wire to a lamp cartridge. Now the lamp should light up.
4. If pressure in a current carrying cable to a lamp is not present also a control lamp does not light up, switch damage is probable. Check up the switch.
5. Otherwise check up the lamp module.
