Wiper Motor Power Supplies and Connectors

1163 Views 7 Replies 5 Participants Last post by  Ghost Ninja
Hello all, I need to order a new power supply and I came across at least two different sizes. Fright Props lists their connectors at 5.5 mm x 2.1 mm and many listed on Ebay and elsewhere are listed as 5.5 mm x 2.5 mm.

So my question is will they work interchangeably? I suppose I could cut it off and attach my own female end to match.

Second question, on Ebay I see a lot of low price power supplies that seem to be designed for printers or monitors, but they are 12v 5a. Would they work on wiper motor prop?

Thanks in advance.

Thanks J-Man!!!
Point taken. I've actually done it right and wrong before. Many wall warts have a diagram showing which part of the plug (inner or outer ring) is + or -.
