Yashica MG-1 Repaired and Mod

Same Camera from the previous post. Yashica MG-1.
I don't have time to test it out. Notice something which i did take note off during the first repaired. MG-1 have to light indicator which enable us to take note during the exposure. Overexp. or Slow shutter speed .

I happened to test it out just outside my house. Realize that the overexposed light indicator did not light up, and of course the slow light indicator works fine.

Here i go again troubleshooting where might go wrong, or simply the bulb just blows off.

The bulb dead. Replace it with 3mm led. Since it consume less voltage and current. Point check with DMM , it can goes more than 3v depends on the light intensity falls to the light meter.

Cut out the wiring of and solder the respective point of - and + side of the led. At this point of time, i fix the problem. Led works on during large aperture setting, which means over expoure.

The light did not give much intensity on the bright sunny day outside. Very small of amount of light to indicate it to be over exposure definately hardly notice. If u excidently forgot to dial in to the corrent expoure setting.

As a results, i have no choice but to changed to 5mm led which gives out higher output and since the led are way to big to slot in internally at the actually of the camera. i Mod it by placing the Led outside. Since theres a small hole located there, the led are nicely placed outside. The Led works better this time.

The Led placed out side did not give and problem with the original ones. but i think it serve the purposed to reworked.
I definetly have to test roll this camera out during weekend.
Happy Great Weekend Part People.

Yashica MG-1 internal/repaired

Solving MG-1

A quick sneak into the internal part of Yashica MG-1.
Friend of mine gave this to me cause he say its broken.
Since that the led is functioning and only the shutter gave a buld mode everytime, I assume the light meter is working and there might be part loose connection to trigger the shutter.

Spend about couple of hours in my workplace to partly dismantled the camera.
My guess is right, fixed the contact and it works now.
The camera are now good to go and well clean by me and DamageDigital

Below are pic of internal part of the camera and the cause of it to not triggering the shutter.
No harm trying to looked into the internal part if u knew what u are doing and if its really cant be fixed, at most just make it into a collection.
