I have the regulator 7805 I need to know what color wires should be coming off the regulator with the regulator on my desk with the leads pointing at me and I can read the 7805 do I put the red wire on the left and black in the middle then the white on the right. I am also wanting to know what
gauge wire to use and how long to make them.
The regulator is from RadioShack and it is for my sport trac with sub and amp I am installing a Pioneer AVIC Z3



Thanks !!!!!!!

 

Rhite95: The LM-7805 1 Watt Voltage Regulator can supply a current of 0.5 Amp@+5VDC continuous when driven by a 15 Volt source.
The mounting tab is at the ground terminal the same as the center lead.
The T0-3 package if placed as you have stated has it's "input" lead at your left hand. The case of the regulator;which is the center lead goes to the ground (-). In your case this should be the black lead. The output lead for +5VDC lead should be to your right. If you ever get confused the output lead is always at the end of the "7805"text printed onto the case.
The red lead should be traceable to the +12VDC input lead on the unit. Do you have a reliable voltmeter?.
To make sure check the resistance between the red lead to the VR to the +12V or battery input lead of the unit. There should be a definable amount of resistance if you have found the correct lead, and a reading of extremely high resistance over to the white lead.
The size of the wire to and out of the VR shouldn't be a problem considering the low amount of current controlled.

 

That was a big help thanks !!!!!
