The PowerBook 500 series AC Adapters are very unreliable and just generally awful. The usual cap failures and leaks, but many just refuse to work even after a recap. I recapped two that would work for a short time and then die. Both had leaking caps in them, but still didn't work right after the recap was finished.
If your original doesn't work after a recap, I'd recommend building an adapter to power your laptop off a modern 16V supply. Details on that are available here.
The hardest part of either method is just getting the plastic case open. The best method to do so seems to be to bust it open with a vice and a couple of pencils on either side of the seam to guide the stress to that area. It got both mine open, but caused a pair of chewed up cases. There's no way to get them open without damage with how brittle they are.
How much work on the vice it takes to open one can also vary. My first adapter took a lot of work and extra prying while clamped before it finally gave, which my second one snapped open nearly immediately.
