Hi all,
My Yashica Electro 35 GS had its default shutter speed (without the battery) modified to 1/60 (instead of the 1/500) a long time ago by a repair shop, since at that time I was small and did not have the replaced battery.
Now I have learned enough about its wonderful capability with the battery and want to restore the camera to its original condition.
Can anyone tell me what it was modified to change the default speed to 1/60? I'm afraid it is something mechanical, which I will have no chance to revert that.
Thanks in advance for any suggestions.

By definition it will definitely be mechanical and presumably in the shutter, but not sure what. |

Anyone know what piece of hardware inside the Electro 35 GS that define the 1/500 default shutter speed, as seen from this attachment photo? |

Ah, found it. It's the Capacitor-Shorting Switch Eccentric which adjusts the top shutter speed. It actually says that in the manual (only I never noticed it before)on page 64, under the circuit diagram. |

So which way (turning) adjusts the speed and what method would you use to do the adjustment? Is it hit'n'miss or very easy? |

I'm afraid I know no more than is in the manual. Never had reason to fiddle with this. But I imagine it should be pretty obvious assuming you can see the contacts. basically, the sooner the contacts make, the shorter the shutter speed will be. I think you'd need some form of shutter speed tester to set this though otherwise it would be guesswork. |

Thanks for that. Will try it when I put my lens back together cause I know I fiddled with that screw when I dissassembled my lens. For some reason I though it also had to come out when I removed the switch. (dumb i know.) |

Update, It turned out to be super easy to find the fastest shutter speed as monopix said it's easy to spot the eccentric when it gives the least amount of gap. I put my lens back together and it worked fine. |

thanks Monopix and Paolo. Will try next time when I get my time on my beloved Yashica. |
