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.

Model 2011 jay flight g2 when hooked to AC power has 120 volts on external TV connector. Can I get an electrical schematic for the 29RLS floor plan?

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:
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.

Hi, i need to know the exact power plug so i dont have to run the pedal on battery power.i know i need a 9v power supply but i dont know the size of the jack that goes into pedal..many thanxs..

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!

External power problem

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.

How do I obtain a "Date Battery" for a Canon PowerShot G2?

Please see page 130 of the following:

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.

Unable to load cf card in slot


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.
