Okay, I got the picture now. Dumb Streamyx, had to disconnect and reconnect just to view it. I have a few questions... how do I find the resistance of the resistors? Do I just point the multimeter heads at both of the resistor's connects? This can be done while the PC is off, right? Any tips on how to get the resistance of Point F? I can't see which point of the resistor that corresponds to the shunt regulator. By the way... before I go further, I think my multimeter is screwed. After setting the voltmeter range to 20v, I get awkward readings like around 270 on my multimeter when I test it on a 1.5v battery.  Again, please excuse me for the noob questions. |

QUOTE(Shah81 @ May 24 2006, 03:30 PM) measure the resistance with the card out of your pc. point the multimeter to both ends of the resistor to measure resistance. i cannot show you where point F is because the picture that you gave me is not clear. try taking a close-up picture with macro mode turn on and at highest quality and make sure your hand is not shaking. you can find it yourself using continuity test with the multimeter. on the shunt regulator, find the leg that is connected to both of the resistor (2 & 3). that leg is Point F. the point where the resistor is connected to the shunt regulator leg is also point F. for voltmod, u can try to lightly pencil on top of Resistor A (its either resistor 2 or 3, i dunno you have to tell me) or solder a pot from Point F to ground. but i need the resistance value to determine the value of the pot. Alright, I'll do that. I'll try it soon as I get another multimeter. It read 2.1 volts on a 1.5v battery, and 1.9v on my core voltage. Obviously, the multimeter must be screwed. Thanks for the help. |

A clearer picture of the area.  |

How do I determine the resistance of Point F, which is a node? What should I do to find out which resistor end is connected to the mosfet or the shunt regulator? Do I find the resistance, current, or voltage? I should be able to get the readings by tomorrow. Sorry to make you wait.  This post has been edited by colinwong89: May 25 2006, 01:29 AM |

To be honest, I'm not very good in using a multimeter. As I said, I'm a newbie when it comes to circuits and electronics. Readings will come out soon. |

Sorry for the long delays because I am unable to get a multimeter in hand yet, but I'll give you the readings ASAP. |
