Hi guys. I just bought a battery for my Konvas 7-m and tried to run it. (I had never run the camera before) I used a Bescor 12v 7amp battery with a 4 pin XLR. The motor does run. But it runs very slowly, not even 1 frame per second i would say. I am wondering if this is a motor issue or a battery issue. Maybe the motor needs to be oiled, or the battery isn't putting out enough power. I have no idea. I need help!! Please!

Is it a new battery? Old lead-acid cells can take a few charge cycles to break up the 'dendrites' before they start working properly. SLAs can crank out vast amounts of current - I have started my car with a 7aH gel-cell. I suspect it's the camera.

Thanks for the reply! I sent the camera to a repair guy, and he got the camera to run, but for some reason it only runs at 24 frames per second, no matter which fps the knob is pointed at. I've heard of this before. Does anyone know why this might be?

Sounds like you are a victim of Konvas electronics. They say that all Russian camera electronics will fail, in time.

.... They say that all Russian camera electronics will fail, in time....


Often the takeup hub is set to a *very* high torque, which will stall and burn out the motor or drive circuit when you actually thread film. And it seems to me I had one model in here with what looked like TTL (5 volt) logic running on 9 volts on purpose.

So if Bush starts WWIII next month by attacking Iran, maybe we'll have a fighting chance since Russia's ICBMs also have Russian electronics, from the same factory I hear. ... ;-)

Hi

=Hi guys. I just bought a battery for my Konvas 7-m and tried to run it. (I had never run the camera =before) I used a Bescor 12v 7amp battery with a 4 pin XLR. The motor does run. But it runs very slowly, =not even 1 frame per second i would say.

If you have problem with camera, you can ask me detailed.
I'm camera mechanic repair of Konvas,Kinor cameras.

The first questin, What motor have your Konvas camera ? This si 17EP-16 APk or 15EPSS or any other ?
The next test. You need disconnect motor from camera and run motor separately.
Cam be problem with camera, motor, power cord, battery and more other.
From my experience, all Konvas cameras need service and re-lube.

I use my Konvas-2M camera with 17EP-16 APK motor with 12v 7 ah battery and battery work very good.
