I broke on of the 9vdc pins off and i am looking for a schematic for the power as i am unsure of the polarity of the pins, can some one help so i can make another type of mains power supply connection.

Re: powershot g2 power schematic
I doubt you will find such a thing- altough- Canon web site tech support may have a clue. but you should not need it if you have the skills to make such an item- just make it and stick it where the other came out.

What you are saying is when you connect that motor home to a shoreline power connector, the outlets are reverse polarity. You can confirm that with something like this: http://www.acmehowto.com/electrical/outlettest.php
You can get this tester at any hardware or lumber place. What caused this? Somehow the polarity got reversed and it is most likely at the connection on the outside socket. It can also be the shoreline drop cord or the breaker box. In an electrical outlet, the small slot is HOT and it should be connected to a BLACK wire. In an appliance like a television the neutral wire (white) is connected to the ground or the chassis of the device, when the polarity is wrong the chassis becomes hot and you get the problem you describe.
Unfortunately, battery jacks and plugs similar to the type you're describing do not have any real standardization - unlike the outlets and plugs in homes and businesses have.
You best bet is to either bring the plug / jack to a shop to match it or contact the instrument's manufacturer to obtain the connector specs for physical dimensions
Be sure to obtain the power requirements in either watts or amps so that you can obtain a power source capable of delivering what you need without overheating during longer periods of use. Adding 25% to 50% more amps or watts to the minimum required should provide years of trouble free service. Example: 9VDC at 50 watts should be supplied by a 9VDC 62 watts or even 75 watts; or in the case of a rating of 9VDC at 6 amps should be supplied by a 9VDC at 7.5 amps or even 9 amps. With DC powered devices, make sure you observe proper polarity! Good luck!
It's actually the opposite. 1/8" jacks are almost always positive tip. I think you are best off using a 9VDC supply. If the voltage is not staying constant at 9 volts it could certainly do damage. If the supply you used was a negative tip positive sleeve you may have burned out a component or two...and more voltage than recommended could have done some other bad things. If it does not work with a 9VDC supply with the correct polarity you can fix it yourself if you have electronic experience. You could also send it to me and I'll fix it at a reasonable rate.
The CR2016 is a very generic button battery. Take a look at your local pharmacy such as Walgreens or Rite Aid. Have even bought them at Walmart's watch and jewelry department (Though Walmart was shockingly more expensive than the pharmacies). Shouldn't cost more than 3 or 4 dollars.
The pinholder inside the camera has a bend pin or broken pins. You must let it repair. Ask Canon for an proforma invoice. Rotronica in the Netherlands can repair it for you, the cost is approx. 75,00 Euro.
