Bring Dead Ni-Cad Batteries Back To Life

Step 4 Remove and add switch

After the camera's circuit is removed from the frame, we need to remove the surface-mounded charge switch and add an external switch. Doing so, you will have easier control of the circuit and less likely to get

Remove the top bit of the charge switch. It will have some tape on the top, so it shouldn't be too hard to remove.

Then solder two pieces of wire on both exposed metal tabs. And solder a 'new' charge switch onto the other ends of the wires.

Is there any reason you cannot remove the flash bulb, wire the battery holder to where the bulb was, and use the camera's flash charge button, and shutter button to activate the flash? It would save you 2 switches and keep the dangerous electronics inside a nice case. I don't know electronics that well, but I would have thought the capacitor is wired directly to the flash bulb and this would work the same. would it?

thats how I done mine works great too

i did it that way and it worked. but i had to put in a new switch because the shutter fell apart when i took the cover off. and it works well. fixed my first battery a few minutes ago.

I used a polaroid fun shooter. I soldered my jumper wires to either end of the flash bulb leaving the bulb connected. I was actually able to put the case back on. This almost completely eliminates the chances of getting jolted. I found that I don't even have to use the rewind machanism. just hold the recharge button in until the light comes on and it's ready to fire. CAUTION it appears the it will somewhat recharge without holding the button. So whe not in use I tape the lead ends.
