Francis, 3 pin voltage regulators have the following;
1 pin is INPUT, let`s say 12 volts
1 pin is OUTPUT, let`s say 5 volts
1 pin is GROUND, all electronics equip. has to have a ground
the problem is they are not all wired internally the same so how do you tell which is input pin and which is output pin ? the best way to find this info is find the data sheet on-line. Google the letters NTE and click on their cross reference link and then enter the number on the front of your regulator and it will cross your device to NTE`s device and show you the info, hope this helps you, Happy Holidays BMW Rider
