Picked up a Konica C35 FD without meter operation, on opening sure enough the cables to the battery compartment are loose, not connected.
I am new to repairing cameras, now very curious if the meter will work, thus my questions:
Which cable should be connected to +, which one to - ?
there is a yellow cable running deep into the camera towards the lens, and a blue one running sideways, please see the photo below.

I did not dare to try out myself not sure if it would damage the camera if connected the wrong way around.

thank you for any input,
Andreas

P.S.:
sure I should be able to find the answer searching, but please let me also ask:
in case I get it to work, should I add a diode to cut the Voltage of the LR44 from 1.5 to 1.3? If so, what is the name of the diode, and how to connect it? after the + of the battery?
or better operate it with 1.5 Volt? If so, in which way to change the ISO setting on the camera to expose correctly?
thanks -

A #675 hearing aid bettery has a constant 1.4 volt output. Obtainable in most pharmacies, may need some shimming to fit properly.
