HEY!!!! WAIT JUST A MINUTE!!!! I JUST LOOKED AT THE PICTURE THAT I POSTED UP AND REALISED SOMETHING! ISNT THE DIODE INSTALLED BACKWARDS???!!!?!?!?!

Hey, thanks for the input. Well, I think I used a 5 ohm resistor, just as Paul suggested (I think can confirm that by looking at the first pic to see the colour codes on the resistor). Ok, guess I will have to try it out on those parts you suggested Paul. When I get the time, I will...

Hopefully this picture is good enough for you. Yup, there are the same AMC 7135 chips. At least I think they are ( i thought DX that I wanted the same replacement, and they gave me these). They look like the ones shown in the picture on their website. Dude...seriously.... frustrating to be...

The black wire from the batteries is soldered on to the outer ring, while the red wire is soldered on to the inner ring.

Hey Paul, Well, I received a new set of AMCs from Dx. They look like the original ones that were on the website photos. Unfortunately, I wired it up, AND IT STILL DOES NOT WORK!!!!!!!!!!!!!!! AH!!!!!!!!!!!!!!!! I have attached some photos of my connection. Do you mind telling...

Hey Paul, Sorry was away for sometime. Had to deal with some exams and stuff. Anyway, I have asked DX to replace my AMCs and they will be sending me a replacement. When I receive it, I will get back to you. Hey, thanks for all your help man. Will talk to ya later. :)

Hi Paul, Tried it. No effect. :( Could it be that the IC itself is spoiled? (a bad batch perhaps) Anyway to test?

Hey Paul, I tried it but could not find a continuity between the positive side (where you connect the batteries) and the negative side (where the LD connects back to the AMC circuit). So does this mean that the internal circuitry has not been soldered on properly etc? I think I...

Tried it man....added a bit of solder on the pins just to make sure there is proper contact.....but still no result. :( :( :( :( What am I to do?

As well as the tab on the IC? What do you mean by that?

Yes....about 3.6 Volts

Here you go mate. I have shown the opposite side of the AMC so that you can see how I have wired it

By the way....the pic is of a brand new board that I used to try Paul's wiring setup

let me explain the pic. I connected the ground going to the batteries to the outer ring on the back part of the AMC. Later, when it did not work, I tried wiring it to the exact same area that you pointed. No effect as well. The positive is soldered on the centre ring at the back of the AMC.

here you go.

Hey Paul, I tried your wiring with a new AMC7135, but it does not seem to work. I wired it up exactly the way you said to, but I used a 5 ohm resistor so that I can calculate the current. But when I tried to measure the voltage across the resistor, nothing. Back to the drawing...

Preliminary testing: I modified my old AMC circuit to match yours, and i placed a 5 ohm resistor to measure the voltage across the resistor. Unfortunately, not seeing any voltage change (i.e. my multimeter reads the voltage as zero as if to say that there is no current passing through).  ...

Hey Paul. OMG!!! Are you absolutely sure about the wiring that you drew out on my AMC pic? Cause if you are, I have just found the source of my problems. I HAVE BEEN WIRING IT UP THE WRONG WAY!!!!!!!!! You see the 2 little holes to the right of the '000' resistor, I wired the...

Guys...I'm sorry, but I dont have photoshop...so I cant shrink this photo. Sorry.

Here is how my AMC 7135 looks like. I dont think I am wiring it up the wrong way, but just to confirm. Can anyone show me where I'm suppose to connect what?
