Bought an after market power supply for my 290 has a universal polarity plug. Is the bike set up for positive polarity on the center pin or negative?

I don't know. If you use batteries you really do not need this adapter. It actually gets in the way of the pedals.

Dear Piero, Using the key provided turn the orange disc on the left to +. in the middle of each disc is a tiny arrow shaped opening to put the key in. On the right turn the arrow to the voltage you need. On the back of the box it states " If the product does not function, change the polarity. That is all you need to do.

Usually you use the two outside terminals or whichever ones are marked + and -. Polarity does not seem to matter to the charger.

There is no polarity on the switch. Connect the one to the POS+ from the battery and connect the other to the POS+ to the pump.

Sorry, but I don't remember. Mine was used with a 12v DC converter for a light strip, so polarity is a definite concern

Hi Mike,my power supply adaptor is 12 volt,2.5 Amp.part # 18778.the +pos is on the inside of the post plug & the - negative ground is on the outside of the post plug plug that plugs into your 12 volt port.

Wires hook to the posts on coil , one side is negative and other side is positive

Sorry I do not remember the polarity only that it is the same as the battery pack that it is to replace and it works fine in that application.

negative or positive voltage is simply a reference to ground. reverse your power connections (leads) and you now have negative voltage. it does not have a dual output for both positive and negative voltagesgood luck

I use a 1 spot power supply, negative is the center, positive on the outside.

What are you using "load" for? I plugged the Schumacher solar panel into the "power" connector and the "load" connector is not used. If you are using the "load" connector for an accessory and polarity is important to you, examine the leads on this item. It shows the positive and negative terminals. The red wire is positive and the black is negative. http://www.amazon.com/Schumacher-WM-12-Connector-Battery-Maintainer/dp/B003WDDLTO/ref=pd_sim_auto_4?ie=UTF8&refRID=17QWYESMERCBD397V2K6

center pin is positive. The all metal that you see just inside the rubber is negative. Any question 719-331-6199

I use a generic one, with interchangeable connection pins and variable voltage (but fixed 3A). Set it to 9V, center pin positive connection, and you're ready to go. I'm pretty sure you can find one here.

Thanks, i'll check for the switch on the back tonight. i'm sure the polarity is correct, red to lead (+) and black to ground (-) right?

No polarity does not change, With out seing it my guess would be the plus and negative signs are taking the place of male and female. In other words if you were using a single connector you would insert the male part into the female part of the connector. I have many panels hooked together with these connectors and it doesn't change polarity. I would recommend phasing plus wires from panels with red phase tape and phase wires back to invertor or charge control, makes it a whole lot easier to keep track of what is what.

The center wire should be Positive. Sorry that's the best I can tell you, it's been way too long since I installed mine.

Polarity should not be an issue. Also these are probably a little large for an instrument cluster.Check for cross reference guide for what you have now.
