You're a lot braver than I am. I wouldn't have given that board power at all without knowing for damn certain that the whole thing wasn't going to blow up in my face. It's obvious now that the upgrade either isn't working or isn't wired up correctly. I wouldn't risk powering it up again until you figure out what's what. Those original 128k motherboards are too hard to replace if it should be damaged by experimentation with an 'iffy' memory upgrade.
If you're really after a 512k upgrade to make your 128k machine useful (and a 128k Mac is basically a big doorstop without one), then $100 gets you an official Apple 512k motherboard practically any day of the week on ebay that is a simple swap with no soldering or rewiring necessary and you can always go back to the original 128k motherboard (minus the memory upgrade) at any time if you want to sell or restore it to original condition.

I guess it pays to know what one is doing then, and I do. Plus I have several spare boards, really don't care if a couple blow-up, even thought thats impossible.

You know damn well what I mean by "blow up", but in case you really are that dense, I mean burn up other parts on the board that would render it fully or partially non-functional and whether you have more or not is irrelevant. It would be irresponsible to knowingly damage such a rare part knowing how many people are looking for one and how rare they are. It would be like buying the Mona Lisa then painting a mustache on it just because it's yours and you can. You ruin it for everyone else who appreciates it the way it is.
