ok so i thought i fried the bettery on my 450r because it wouldnt hold any charge. When i picked the new one up, the guy at the dealer said it was charged and ready to go. So without checking anything i just hooked it up. No power! So i through it on the charger and it seems to be doing te same thing as the other battery. It wont hold any load.

Could it be a defective new battery?
Does it not hold a charge after you charge it, and before installing it or after installing it?
If it won't hold a charge while not hooked to anything I would say it was bad.
If it drains while on the machine then there are several things that could cause it. First thing that comes to mind is that most replacement batteries have the post opposite, negative is located where positive was (physically). In that case you probably would have blown the fuse. So we know it is hooked up correctly. Then it would seem like there is a bad ground and/or the terminal connections are loose, or you have a worn wire with a short someplace that is draining the battery.
Maybe some of this may apply.
Problem: Magneto does not charge
Condition Remedy
1. Lead wires/connections shorted - loose - open 1. Repair - replace - tighten lead wires
2. Magneto coils shorted - grounded - open 2. Replace magneto coils
3. Regulator/rectifier shorted - punctured 3. Replace regulator/rectifier
Problem: Magneto charges, but charging rate is below the specification
Condition Remedy
1. Lead wires shorted - open - loose (at terminals) 1. Repair - tighten lead wires
2. Stator coils (magneto) grounded - open 2. Replace stator coils
3. Regulator/rectifier defective 3. Replace regulator/rectifier
4. Electrolyte low 4. Add distilled water
5. Cell plates (battery) defective 5. Replace battery
Problem: Magneto overcharges
Condition Remedy
1. Internal battery short circuited 1. Replace battery
2. Regulator/rectifier resistor damaged - defective 2. Replace resistor
3. Regulator/rectifier poorly grounded 3. Clean - tighten ground connection
Problem: Charging unstable
Condition Remedy
1. Lead wire intermittently shorting 1. Replace lead wire
2. Magneto internally shorted 2. Replace magneto
3. Regulator/rectifier defective 3. Replace regulator/rectifier
