When I tried to put a battery charger on either of the post, it is arcing. It didn't do this yesterday.
Is there a short somewhere? Why would it do this? The charge is not plugged in. As soon as I go to put a cable on the post she either sparks and or arcs.
You are getting arcing from the battery to the charger with charger unplugged from the wall? I suspect you need a new battery charger. It shouldn't allow current flow backwards through the charging circuit. Either the diode bridge (cheap charger) or transistors (more expensive charger) should only allow current flow to the battery.
Get a cheap voltage tester ($10-20) and a battery specific gravity tester ($3-4. looks like an eye dropper with little floats in it.) to test your battery.
Use the multitester to check your batter charger when it is plugged in.
Put a space heater blowing into the back of your engine compartment for a couple hours. The PT doesn't like cold starts because of all the cold hydraulic fluid is fighting your starter motor. Unfortunately with no clutch, the engine is always under load during starting in cold weather.
Check the fuel filter to see if it has fuel in it (common problem is clear plastic debris collects in the elbow at the bottom of the fuel tank and prevents any fuel from flowing out of the tank). Make sure your fuel filter isn't clogged.
Someone early mentioned the PTO switch. This switch is designed so it prevents starting your engine with the PTO switch on (the starter motor won't even spin). Make sure it is off. Although, since you are getting it to cough with starter fluid, IO am assuming you are actually getting it to spin.
Sounds like a cold start or fuel starvation issue.
