Follow the big wires into the engine hood - just do the same thing at that end while it is disconnected at the battery end. Also check the two eye terminals (I guess that's what you'll have at the engine end) are still firmly connected to the wire.
The fact nothing works is likely either a dud battery or a dodgy connection. You say it is making a fizzing noise - where is that noise coming from, and does it come from the same place when you use the starter & the PT? If so, that place where the noise is coming from is likely your problem.
Assuming it's a bog standard car type, they die slowly and accept less & less charge as they die, so (and I put this in a graphic way to illustrate the point, so all you electical nerds hold back with the comments please!) - you end up with a huge mass of battery with the capacity of a couple of AAs. Problem is your charger is unable to tell the difference between a gubbed battery and an almost fully charged battery that need a top-up.
Could test whether it's the battery by trying a jump start from your car. (needless to say keep the deadman off unless you have it in a bucket or on muffs!)
Anywhere I could point you at would be a bit far north!
