Finally got my 14 and took it out on a night shoot the other day. While weapon mounted and after a few shots the unit turned off? I clicked it to the reset position and turned it back on, no problem.  This happened several times.Then last night I was doing an area search for a smoker who jumped out of their car after a pursuit. I had the 14 head mounted while riding shot gun. Same problem. It would just shut off. This seems to be related to "shock" or bumps. Any info would help. Is this normal. Seems to have the potential to be unsafe given the right situation. What to do????? |

First thing to do is check the battery compartment for loose connections. The spring action of the contacts maybe to blame. But I know a certain someone who will chime in with much better information. Does your 14 have the mount removal auto off feature? JohnM at Home |

The auto shut off is accomplished with the swing arm mounted to the unit and then inserted into either the halo head harness or the “Rhino” helmet mount. What happens is this. If you swing the Rhino mount up or disconnect the swing arm from either mount, the unit will automatically shut off. This is a battery saving measure as well as a "tactical not give your position away by having a bright green light source shinning for all to see in the darkness" thing. This only works on the PVS 14 and not the 6015. Does your unit have brass or silver contacts in the upper housing? Does the battery pack have a variable gain knob? Now your problem sounds like a failure of some kind. There are a couple of possibilities. First let me ask, does anything rattle inside the unit? If so the tube-retaining ring may have come loose and the tube is actually moving off the electrical contacts. If there is not rattling then the contacts may not be making proper contact with the tube but I kind of doubt it as the reset function is working. However here is a brief explanation on the contacts. The electrical contacts that provide power to the tube are in the battery pack on top of the circuit card that controls the unit. They are a pair of small spring like dual fingers that press up against the tube body making contact with the electrical inputs for the tube. Now if you remove the four screws that hold the battery pack on you will be opening the unit and you will loose the nitrogen purge that is in the unit. If your not concerned with that then simply remove the screws. You will see electrical flex print coming from the tube to the board and two more flex prints coming from the back sides of the contacts in the upper housing. Make sure both of those are connected. Once you are sure everything is plugged in and the contacts are making good contact reassemble and test it out. If it still does it you may have a failing battery pack. IM or shoot me an email at [email protected] and I can shoot you a very reasonable quote for repair of your unit. IPSC_GUY SIERRA II ALPHA |

IPSC_GUY, Thanks, you know your shit! I have the TO for the 14 so the suggestions you made should be easy to test out. I'll have to wait until the weekend to try all of this out. I think the shut off's related to the head mount are due to removal from the rino head set. I never knew this. Thanks again for the detailed reply! Man it is nice to talk to people that REALLY know what's going on. |
