I know this has come up but I figure I would ask...When connecting a wiper motor to 120v house current, what converters is/are everyone using?

What is the cheapest converter to buy? Any links is appricaited....Thanks all...

I use computer power supplies. These have multiple uses for different voltages, 5v 12v 3v etc. Have plenty laying around from old computers. You could just use a 12volt adapter plug that turns 120v to 12v.

I'm using a wall-wart with adequate amps and a appropriate voltage to slow the rotation.

I know on the plugs there are a red, black, and yellow wire...Which are you using to connect the motor to? Red and black?

And what's a Wall-mart?

Check out Monster guts. They have 12 volt and 5 volt power supply at 5 amps.

On a computer power supply, red is 5V Yellow is 12, and orange is around 3, you can use either to run a wiper motor as they both put out a lot of amps, 5 will turn it alot slower i believe. you will also have to short the green wire to a black wire to activate the power supply.

wall warts are the small power supplys that come with everything, and come in all different voltages. they are the annoying black box you need to plug in and rarly ever fit in a power strip, with out wasting at least 2 outlets

thanks gang...I have about 3 power supplies at home now, so looks like I am set..need to hit the junk yard this weekend

I also us a 12v 2 amp power supply I got from All electronics.
