I need a replacement diode that runs from the batt. light to the alt. its in the brown wire, I called radio shack they only carry 1N4001 AND 1N4003 NOT 1N4OO2 WILL ANY OTHER DIODE WORK THAT I CAN PURCHASE? THANKS

A 1N4002 is a general purpose rectifier diode good for 1A and 100V reverse.

A 1N4003 is the same thing, only it's good for 200V reverse. Anything up to a 1N4007 will work just fine.

Thank you

PROBLEM SOLVED after all my questions and taking up all of your time, it was in fact the bulb issue, i have a good bulb it just needed to be seated a little better to make good contact, charging like a bull,, again thanks forum for the help,, c-note

Correct. The forward voltage drop of the 1N4003 will probably be slightly higher than that of the 1N4002, but not enough to matter in this application; both will be ~0.7 volts forward drop. A slightly higher forward drop is one price you pay to achieve a much higher peak reverse voltage.

Over the years I have used tons of 1N4001s and 1N4002s in a wide range of applications. They are probably the most universal and generic 1-amp diodes on the planet.

HATS OFF TO YOU GUYS THAT UNDERSTAND ALL THE DIODE AND RESISTOR TALK,, THAT IS ALL FORIEGN LANGUAGE TOO ME,,oops dam cap lock,,,

@northstar, it’s not so much of a rocket science actually, just grabbing the concepts for people without basic electronics knowledge is a bit tricky. What matters in case of transistors are two things, if they are NPN or PNP and whether or not they will fulfill your specifications. In this case you can note that the series of transistors 1N400X has more or less the same function, they might come with slightly different ratings though and depending upon the ratings, price will differ. There can be so many different series like 2N22X, 2N23X and so on. Guys at Radio Shack know this stuff, next time, just mention the part number and where you want to use it and they'll recommend the nearest match even if they don't have the exact component.

Well there ya go.

Actually the 1N and the 2N refer to the number of junctions in the device. A 1N device is a diode. It only has one junction. It only has 2 wires attached to it.

Transistors are 2N devices. They have two junctions. They have 3 leads to them. Like an Oreo there are three parts, but 2 places that the creamy white middle "junctions" with the outside cookie.

NPN and PNP refer only to transistors.

This discussion was about diodes and not transistors. All the numbers stated above are for diodes and not transistors.

Finally the guys at Radio Shack know some about cell phones but don't know **** about what is in those drawers back in the corner.
