Question about ITT Night Mariner 160 Monocular

1 Answer

Battery contact One of the battery contacts deep in the unit appears to be pushed into the housing. This seems to be causing a NO POWER situation. How can I get this fixed. I am an American going around the world in a small boat. I am in Thailand and would like to get it repaired before we depart for India. Fred

Re: Battery contact

I hope you have a temporary export license cause if you don't you have broken a Federal law with penalties of imprisonment and/or Fines. Night Vision, especially Gen3 night vision is highly restricted and "CANNOT BE TAKEN OUT OF THIS COUNTRY" with out licensing.

Wont turn on with new battery in it

Is the new battery actually new? or is it a good one pulled from something else? This can make a difference. I have also found bad batteries on the store shelf.
It is also potentially old enough to have a layer of corrosion develop on battery contacts, Sometimes rolling the battery against each contact and then installing the battery is enough to cllean it to operational conditioin. Also make sure battery is installed in the correct orientation.

They also have a fairly short imaging tube life too but you would see some signs of life in the unit.

Batterys corroded clean up contacts now unit does not power up

Jenko, How bad was the clean up of the battery contacts, lot of corrosion? Now it possible to have broken wire to the battery compartment.

If you are mechanical inclined and have some experience with electronic. Here what you do. Remove the front lens. There will be four screws on a concentric ring. Remove the screw and the ring. This unit comes apart in the approx middle. Also, from the front end look for a white Teflon ring with one screw it goes around the image intensifier tube. Remove the screw this will allow the image tube to ability it to move back along with the rest of back frame Be careful here all the wire are white Teflon coated ,all the same color. These wires are HV, and are rated at 2KV with small current. There's a battery tube on the upper right of the back housing. Lots of wire that go to the two switches. Take a pick and gently remove some of the rubber trim cement that was used. The only wire to be concerned about is the ground wire. The positive wire you can see from the back of the back frame housing. There is a aluminum ring that is threaded for the battery cap. Now there is slot cut into the battery tub just under the aluminum threaded ring, you can see the wire. This is the positive wire.

If you don't have the room, remove the plastic cover over the on/off and IR witch cover. There will be six little screws under the plastic cover, remove the screw and the back plastic switching component can be remove the from inside. Make sure all the cement has bee remove.

It is really critical here. take some wire indicators tags. make a picture of the printed circuit board and every where a wire is attached put a tag on the wire and mark the location on the your diagram where that one with its tag is locked. Your are going to find that there are many ground wires to different shielding plates. I can't says it enough, mark those wire and its location on the printed circuit boards

If you need to remove the green image intensifier tube. There a wire teflon cap and cover that goes the voltage multiplier around the image tube. Just gently pull down the white cap, and turn it inside out. Take small pick and remove dielectric jell from inside the cathode. One the jell is removed, then gently pull on the white wire and it will pull out about 3/8 of inch. The voltage multi-
plier ignitor wire is solder to the cathode wire, desolder it. All components then can be laid out.

Check for broken wires. send me another message and I will tell you components to check and how to fire the cathode ignitor. stewbison.

Havent used in a while and left batteries into long and now the screen does not fire up

Hello, Check and do a look see. if the battery compartment contact are corroded. Now, if the green color and crystal have attached to those contacts. Then those wires could also be corroded or broken.

Clean the contacts with a little brush (metal). Make sure they are cleaned to the copper or brass connects. You can do this, but be very careful. Take small rag with just a little water, and rub baking soda into the rag where the water is located. Brush off excessive baking soda. Be very careful, and light rub the rag with watert and baking soda on the contacts. Let it dry, then brush off the junk it could have bubbled up. Do not get this junk in you ATN scope, it can created problems.

When cleaning the battery tray, hold it down towards the table, floor, out side, etc. stewbison

Unit dead, in storage for 1 year, worker good before that

Jenkeeo, Did you leave you battery in your NV for a year? If so, remove the old batteries and clean the contact to all of that corrosion off the battery contacts. Then try new batteries. Let me know what happen. stewbison

Put new batteries in power does not come on.

Hello, check the battery compartment and see if has been corrupted with leaky battery corrosion.
If it has clean the contact really well. Also, make sure you are using new batteries, and the plority is correct while installing the batteries. A kind of rule of thumb here: if it has a spring, then negative (-) is connected here. Unless it has some else, plugs, etc. stewbison

Put in a new battery but the power won't come on. I checked and the + is right.

It can be related to a failure on the inside of the unit if your battery is good and the contacts are fine.
So thebest is to have the tools necessary to open out and check if there is any minor fault of a line break or a possible fusible resistor that opened out.
If you find power to the circuits in order then the fault is in the board and can be the control IC.

I have a pair of atn night cougars and i havnt used them in a year and they needed new batterys so i got some. when i put them in they wont turn on and i cant figure out what the problem is.

if you left the batterys in and stored the night vision for a year the batterys could leak,,,look at the battery contacts inside your units if corroded clean them up they should work then
never leave baterys in the unit if storing it away for more than a month

Battery not making good contact

Hi, I have the night mariner 250 model (Gen 2?), when turning it on it shows the low battery indicator (red) light flashing and then switches off after approx. 6 seconds. It does this all the time, even...

The problem could be caused by dirty battery contacts or faulty capacitor on power supply board.

I suggest cleaning the battery terminals with iso-propanol alcohol and fine emery paper.

If this doesn't work, you really should take it to a repair/service centre.
