Check of filament lamps


1. Remove a lamp and check it visually. If the filament of a lamp 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 also, whether there are no corrosion traces on the lamp case. In the presence of a rust smooth out it a skin.
3. If the lamp is serviceable, insert it into a cartridge and include. If the lamp does not light up, check a food by a control lamp. For this purpose attach a control lamp to weight. Accession 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 break in a weight wire to a lamp. For check put a weight wire to the boss of a lamp. Now the lamp should light up.
4. If tension in a current carrying cable to a lamp is not present and the control lamp does not light up, switch damage is probable. Check the switch.
5. Otherwise check the lamp module.
