Figure 12. (a) (b) (c) Expose the wiring as described in (2) (c) above. Examine all visible soldered joints between cables and con- tacts, cables and switch, and cables and reflector. Soldered connections must be good and firm. Inspect the cable leads carefully for breaks and cracked insulation. Using a 6-volt test light, test each cable for continuity. Test the cable connecting the upper contact to the switch by placing the switch in the “OFF” position and touching one lead of the test light on the soldered joint of the con- tact and the other on the soldered connection of the cable to the switch (fig. 12). If the lamp does not light, the cable or its connection is defective. Check the cable leading from the other side of the switch to the contact or the reflector as- sembly. Snap toggle switch to “OFF” position and place one lead of the test light on the soldered connection on the switch and the other lead to the soldered connection on the reflector lamp contact (fig. 13). The test lamp should light or the cable is defective. .Aiming lmst lights M14 md J143 Ilave two eontucts inside the cwse, the 10IVW one of which is not wsily :lcwssible for visual illslwcti(nl or cllwlii]lg.
