Hi Guys, I'm in need of a little assistance

I've just moved house - which is good - and managed to unpack my Amigas for the first time in a few years. Unfortunately no phone line yet, so I have to connect up on my phone, also

Now, I've found that I have water damage on my desktop A1200, which I'm working on once I unpack my IPA.
My main problem is my Power Tower'd A1200 (Apollo 060/66 32Mb, Mediator, Voodoo 3 3000, SB...)
Cutting it short-
It powers up ok and I get the boot screen if I strip it all down to the bare mobo, but I don't even get a flicker from the monitor when the accel card is plugged in.
My thinking is either it's dead, which I'm ignoring for now, the battery is dead, which it almost certainly is, or the crystal has stopped vibrating!
So, can anyone point to common probs that this sounds like or suggest where I can get a new crystal and battery (soldered on variety). I had a quick look on Amigakit last night, but didn't see what I was looking for. Compounded by my lack of connectivity no doubt. I tried searching this site too, but again, not much fun on a phone, so sorry if this has been covered a gazillion times
