I bought this used on the EE. Once the PVS is mounted, it will only stay on for about 30 seconds. No matter the orientation, it turns the device off. I don’t have a manual, so am I missing something simple? All I have done is install device and boom, off in 30 seconds, no matter what. Tried two different PVS’s too.  

For now I just switched to a Wilcox J arm I had laying around  which works with the INVG mount, but it has more slop.

I know I can put tape over the connectors but am trying to figure it out first.

Hmmm no takers here.  Got nothing to say other than, fuckit, tape off the contacts and drive on.  

Who knows why it does that.  Wonder if it did that to the guy who sold it to you, or was it like that from the factory.

I couldn't get mine to work correctly it would always intermittently shut off when I didn't want it to. I think it's a relatively common issue.

You can remove this magnet from the back of the bayonet mount.

My basic understanding is that the magnet is suppose to interfere with the circuit when flipped up, shutting the device off. I had this issue and removing it fixed it. It will no longer shutoff after doing this though when flipped up.

I recommend getting a Norotos DDA for the INVG, because I love that mount. DDA should lock tight.

Remove the switch. Auto off never seems to work correctly.

And not to bust on Norotos on this one.  The auto-off function is notoriously dysfunctional across the board on any -14 housing/system.

Was having the same problem with my Norotos DDA+INVG with a PVS-14. Taped over the auto off contacts on the 14 housing like TNVC said above. Problem solved.

Tape it is… or I’ll sell it. I like the QD of the Wilcox Jarm

I use the DDA on an INVG and just do the tape trick.
