check condition of contacts and reflector assembly with a 6-volt test lamp. (a) Place one lead of the test light on the reflector lamp contact (fig. 15) and the other lead on the reflector. The test lamp should not light up. If the test lamp does light up, the contact is not insulated from the reflector, and the reflector assembly must be replaced. Figure 15. Testing insulation between contact and reflector. (b) (c) (d) TAGO 3108B Remove the two screws (C, fig. 17 (for M14) C, fig. 19 (for M41), and C, fig. 20 (for M43)) holding the contact assembly to the case and withdraw this upper contact assembly. This is accomplished by pushing the switch and reflector back into the case as far as possible and tapping the end of the case until the contact assembly drops out. Note. It is not necessary to undolder the cable leads. Test the upper battery contact (as shown on fig. 16 for lower battery contact) with a 6-volt test light. Place one lead of the test light on one side of the contact and the other lead on the other side of the contact. The lamp should light up or the contact is defective. Install the contact assembly in the case (par. 24c). This is a typical installation and applies to all aiming post lights. Remove the two screws holding the contact assembly in the other end of the case for lights M14 and M43 only. Light M41 is operated by one battery, thereby having only one contact assembly. 23
