N90S advance problem

[t_g3]

I have the MB-10 grip on my 90S. New batteries are in the unit.

 

I just ran 8 rolls of film through it. At least once per roll, when

advancing the film, it would sound as though the film was having

problems advancing. Like weak batteries. The motor groan as if it was

being loaded down.

 

It only happens once, maybe twice per roll.

On one occasion it locked the shutter with 'ERR' flashing in the

display. I had to turn the camera off then right back on again and it

continued to work OK. I don't have the film back yet, so I don't know

if it actually did only half advance the frame. I had it set on Low

speed advance mode. New Lihium batteries in the grip.

 

This morning I took an old roll of film and ran it thru 8 or 10

times. This time I was using a freshly charged set of Ni-MH

batteries. Same problem. Got it to hang once and it lagged down

multiple times.

 

 

Has anyone had this problem before?

I had a similar problem with an F90. I had to get the film transport replaced. Sounds like a fairly similar problem. In my situation, about 10 frames would load and then it decided that the film was finished.

Jonathan, did yours stop altogether?

Mine will continue to shoot the next frame as though nothing was wrong. Except for the one time it got the 'ERR'.

 

Thanks

If you have time, try using two rolls of 12-exposure film.

 

Shoot one roll without the MB-10. Shoot the other roll with the MB-10 attached. Get both processed. If the camera does OK without the MB-10, then you have a problem with the grip add-on. If the camera has problems with both rolls -- send the camera in for servicing.

Try switching back to regular akaline type AA batteries. I'm not sure Lithium

batteries are recommended for the camera bodies by either camera

manufacturers or battery makers. i know that NiMH AA batteries are not

recommended for motordriven cameras.

Do you use AA lithiums or the CR type? If you use AA liths, they were not recommended by Nikon before the F5 came out. For an F5, they don't recommend alkalines (NiMH/lith are recommended). The cameras are designed for different power sources. On the other hand, if you use CR123? type lithiums, then it should run fine I believe.

[t_g3]

Well, I had been using AA lithium�s. I just found the papers for the grip and sure enough they just mention the CR123A lithium�s--with the special adapter of course!

It did list the good old fashion Ni-Cads.

 

Now what is the major difference in the electrical characteristics of Ni-Cads and Ni-Mh?? And I wonder why the CR123A is listed but not the AA size lithium. You would think that both being lithium they would deliver about the same punch. I'm assuming the difference is in the current supplying capability??? Anybody know?

 

I've got a set of Ni-cads on the charger now. I'll try them as soon as they get charged and let everybody know.

 

Thanks for the responses.

Well, I just ruled out the batteries. I put in a set of freshly charged Ni-cads. With no film in the camera I just started firing the shutter. Somewhere around the 15th shot, I could hear the advance motor bog down. It continues to do this every 10-30 shots. Of course with no film in, I don't think it will ever give an error code.

 

I may have a problem with the motor?? Does anyone have a Nikon web site where I can e-mail a repair tech?

 

Thanks

When the N90 was replaced by the N90s, Nikon issued a statement saying that Lithium AA's were okay in the N90s. In fact, they're listed on the spec sheet for the F90x/N90s on Nikon Japan's site:

Thanks Mark. I thought I remembered reading that sometime in the past.

 

I would like to ask one of you kind souls out there if you wouldn't mind doing what I just did yesterday and see what you can hear.

 

That is, if you don't have any film in your N90S, would you please depress the shutter on both Low speed and High speed advance and see if your motor sorta 'bogs' or 'lugs' down. I set mine on manual at about 1/250 sec, but it also does it at other shutter speeds, so I don't think that matters. Oh, and let me know what kind of batteries your using.

 

Thanks all.

I know i'm reponding to this thread a little late, but i'm just wondering if any of you found out what was causing the motor to bog down. My n90s is doing the same thing now even with fresh batteries.

 

Thanks
