Thread: AN/PVS-4 starlight scope repair

Explain exploding batteries a little better. Sounds like a battery short. Are you able to get at the battery wires and test run it bypassing the battery box. Another suggestion is try half charged rechargeable batteries , once the tube lights up is doesn't take much to keep the tube active. These are pretty old Tec and used the standard battery's not the new lithium or Energiser types.

From your description everything internally is operating fine so I would be looking for a short closer to the battery end. I have a scope that drains batteries in hours if left in it so only tighten the battery cap when about to use but that's not your issue. Good luck.
