What is the power supply for this model? ie voltage, current, polarity of plug, and type of plug, thanks

If the recumbent digital computer gives you an option of power supply or batteries then you can deduce voltage of the power supply by counting the number of batteries needed times 1.5 (1.5 volts = voltage of AA or AAA battery).
You can deduce typical current by multiplying the number of batteries by: AA = .05 amps or AAA = .01 amps.
Your next issue will be to deduce the polarity. Look at the Schwinn to look for a symbol that will show you polarity. Typically the center of the plug is: + positive and the outer shell is - negative. There are instances where those two are reversed.
If this is all too confusing then Google the recumbent model number to find replacement power supplies ($35 to $45 US).

There should be information about that cast into the outside of the display housing, Charlie, or it may be printed in insanely small print on the serial number label. Most likely, though, it'll be cast into the housing near the power jack. It'll also indicate polarity, but it won't tell you which size the power plug needs to be.

If you can't find the voltage & current requirements anywhere but you CAN find the little polarity indicator, you could buy a "universal" power supply with switchable voltage and polarity. Start with the power supply set to the correct polarity and the LOWEST voltage. If it doesn't work, step up one notch and try again. Increase voltage ONLY until the unit functions, and NO higher. Tape over the voltage selector switch when you have it right.

Next step would be to check for power from the wall wart (external power supply). Note the output voltage indicated on the power supply, then check for that approximate voltage with a multimeter.

A replacement power supply can be found at most electronics retailers. Make sure the polarity matches, ie positive tip or negative tip, and the plug must match dimensionally. Make sure a replacement can supply the current that the original did (rated in milliamps - MA, or amps A). Ideally an exact replacement would be best if that is the issue. Be careful, and don't crack open that power supply!

It takes 4 AA batteries, that is 6 volts. You will find that a 6V 500Ma power supply will be the right thing, just make sure that the polarity of the plug is right!

Higher current is OK and better than not having enough and it does not do any damage, voltage cannot be higher.
Just think of it like a AAA and AA batteries, both have the same voltage but AAA has less current capacity.
The power supply must be regulated 12vdc though, which will be switch power supply type and also observe the DC plug' polarity (center positive).

All you need to know is:
- The output voltage (usually 12V)
- The rated output current (usually above 5A)
- The plug polarity (usually plus on the inside)
Then just purchase any replacement AC adapter that has the same voltage, same plug polarity and rated current preferrably more (at least 120%) of the original.
That's it.
You can buy them online, for example at http://www.12vadapters.com/

It's OK to use a power supply with a bigger current capacity than needed. If you find once with, say, 24V and 1.0A then that's usable - the wheel will draw as much as it needs.
Therefore:
Same voltage (24V)
Same or greater current (=>0.75A)
Same polarity (positive centre) __________________
Same as the Momo Racing Black, positive inside, negative outside.

The G25 power supply output is stronger: 24Vdc, 1.75A, same polarity.

As long as output voltage, polarity, amperes and connectors are the same you should be fine using a compatible unit, if you find one. In your case it would be 24V, 0.75A, positive inside, but if I were in you I'd wait for some American Driving Force owner to confirm this to be completely sure. The American psu model should however be GAD-SLU-240A8, 110V input, same PSU as Driving Force Pro. Take a look at this for more info. I received this from a forum with people that had the same issues as you and I hope this helps. It seems like they're saying that a store bought universal power supply may mess up your wheel so be careful. If this helps, please leave feed back. FIXYA!

Both the voltage and the polarity should be printed on the case of the router. The polarity should be right next to where the power plugs in.

The polarity information will look something like this:
--(-(+))--

If you take the router into a local Radio Shack, the clerk will probably be able to tell you which power supply you need.

My power supply for my Visoneer 5800 appears to just have kicked the bucket... And, I stumbled across your post in a search for a replacement.

Anyhow, here are the specs off mine:
YHI Power Adaptor
Model: YS-1015-U12
Input: 100-120V 60HZ, 0.45A
Output: +12VDC/1.25A

You should use the original Samsung supply since it is a switching power supply capable of supplying the needed current to operate the onboard charging circuit. Many customers have tried to go with generic supplies and it opens the inline chemical fuse due to the unit drawing heavy current during battery charging. Hope this helps.
