I recently picked up a used one of these:https://tnvc.com/shop/milspec-pvs-14-j-arm/ It seems to be complete, undamaged, and the wiring and contacts are OK. How do I test this to make sure it is GTG? I have a volt/ohm meter, so I can check circuit continuity, but no NVD--yet.
TIA, raf |

Once you get a PVS7 or PVS14 and walk around with it you will realise how annoying the auto-off circuit is and bypass it entirely by using a small piece of electrical tape, or snipping the wire outright.
Honest. Besides dead or nearly dead batteries doing funny things, the auto-off circuit probably causes the most consternation among new and seasoned users alike. When your goggles go dark and you didn't intend them to, your heart will just sink, and your mind will race to "what if's" - did I just fry my PSU? Is my battery board fried? Why is this happening to me? |

Get a magnet.
Get a multimeter and set it for continuity. Connect the leads to the contacts, they will show open or closed. Put the bayonet mount next to the magnet. The meter should show the opposite of what it was before. Here is a link with more info. Gringop |
