Nice evening all together,
I've got a a Contax RTS made by Yashica.
The Problem is, the shutter doesn'nt work, the power LED also.
When I put power onto the connector for the xternal batteriepack, at least the powerindicator LED will work.
The shutter wont.
Because I'm a student and so have no money ;-) don't want to give the camera into service.
I'd de able and handy enough to repair it myself, the problem I have is, that I don't know how to disamble the camera.
So I'd like to know if any one of you has service manuals for the camera and would be kind to send them to me?
I'd really like to photograph with this camera, so please help me if you can.
Yours,
Gregor |

I'm not familiar with the external battery pack, but when you press the button on the right side of the back of the top cover, does the red LED light on top come on? Is the film advance lever cocked? |

As far as I know, the RTS does not have connector for an external battery pack - unless you have the adapter that fits into the battery chamber.
If this is not the case, where did you connect the external battery?

@Jeff, wehen I insert a batterry into the battery compartment an the press the button the LED won't light up.
If I power up the camera via the connector for the externeal powerpack, the LED will light up, but the shutter wont release.
Th advance lever is cocked.
I'v already opened the baseplate of the camera, when I push on the lever of the coil which should operate the shutter, the shutter clicks and I can push the advance lever once more.
And so on. When I push the lever on the coil the shutter will work, i can wind one "picture" further and so on.
@Dirbel, I'm talking of the 3 pin connector on the right side of the camerabody:
http://images.wikia.com/camerapedia/images/7/74/Contax_RTS_II_04.jpg (picture only borrowed from http://images.wikia.com/ I'm not the owner of images rights to this picture!)
2 of the pins are connected to the battery compartement. At least this is what my multimeter says ;-)
Ahm, I didn't use the original external battery I used a adjustable power supply. (voltage was correct also the current limmited)
Greetings,

The 3 pin connector is for the winder. I just verified that the camera needs its own battery even when the winder is connected.
The only easy things I can think of are:
the battery you put in the camera is empty
wrong polarity of the battery - try it the other way round

Hi Dirbel,
interesting to know that the battery's needed when the winder is attatched.
The problem is, that the shutter doesn't work even when the camera is powerd only by the battery.
If desoldered the two wires to the "shuttercoil" and powered it with 4,5V out of batteries. The coil works and the shutter releases.
So a service manual would help me very much, so tha I could desamble the body.

If it is the original RTS model, have you tried releasing the shutter with the self timer or the external shutter release (both electronic)? |

@ Michael,
thanks for the hint.
If i press the battery lid onto the battery without the bodys lower cover, th shuter will work, if i install the lower cover (as like in normal operation with the camera) the shuter won't work.
Outcome... there has to be some connection between circuitry and the lower cover whichs shortens the circuit so the shutter won't work.
I'l try to insulate the PCB (actual the only place where a short circuit can apper in this area in my thought) with a little strap of capton tape.
If this is the solution to the problem, I'l post it ;-)

HAHA, YES!!!
Problem solfed.
The camea works just fine.
The main problem was the oxidised negative pole of the battery compartement.
I cleaned it with a rotary brush and now...
Back in service.
Thanks all for your help.

Damn...
the shutter works fine, I 'v allready done one film.
When i wanted to rewinde the exposed film, I noticed, that te winder lever doesn't work properly.
When I wind, the handle turns endles without winding up the film.
only when i push my thump or any finger on the middle of the knob and turn, it will wind the film, but not really good.
Has anybody an idea, what could cause this problem?
Yours,
Gregor |

After you get your film out, look at the fork on the rewinder shaft. Make sure the tines are not broken off.

@Br1078lum,
the tines aren't broken off.
The problem is the knob itself.
When the lever's layed down it should rotate freely, when pulled up to rewind it ligically should not so that you can wind up the film.
But mine rotates freely all the time.
No missing parts obviosly, has anybody a picture of a working knob?
Yours

There should be a small pin in the center of the rewind knob. This pin is held down by the rewind handle when it's folded in.
The pin is spring loaded and should pop up when you turn the rewind handle.

AH, thought of that.
The spring is missing.
Dirbel, do you also know where the spring is locatet? I think inside the winderrod or?

Yes, that's where the spring is supposed to be.
