Coleco Perma Power Help Please!

Thanks for the info, I'll check it out and post results.

I have seen parts like that grey thing before, but I can't remember exactly what they are. My first instinct was to say a tantalum cap, but I'm not sure that's correct. I'll try to dig out my Perma Power cells and identify it.

Since all these things do is adapt a 6V DC wall transformer to 4 phony C cells, I can't imagine what else you'd need other than a protection diode and a little filter cap.

A decoupling capacitor would fit the bill as appropriate for such a setup, but I don't usually see any that look like solder blobs.

I'm talking about the grey christmas ornament-looking thing covering the righthand battery terminal snap rivet. Has two metal caps on the ends.

Ok, here's what's in mine:

Referencing your pic, the left side diode is an ITT ZY6.2, which is a 6.2V zener power diode.

The right part seems to be a plan power diode, like a 1n4005 or something similar. The one in yours is just a different package, like these:

Now I remember where I'd seen that part before - old British automotive electronics.

The "blob" is where the cathode ends are twisted & soldered together.

Edit: The Vectrex uses that style of diode as well.

Thank you very much and all for the help. Hope I can get working again. Will post results when I get parts, not sure where, and done.
