    Re: Fluke 23 Fusible Resistor

    Mine is a Fluke 23 Series II see attached.

    So as the other components are reading open circuit, is there anything I can do to check that they are working? Without over risking more failures of course.

        Which component??

            RJ1, RJ2 and E1, as in the attached input circuit.

                Many people already explain what those component are and what the reading should be when you measure the resistance, may be you just do not understand how those component function.
                See post 11 and 12.

                    Ok, I can see where you are coming from on this. I'm no expert for sure, but I was hoping that there might be some simple test to check the functionality of the other components. Would Fluke test these protection devices before shipping I wonder?

                    They look good visually so I'll just leave well enough alone. Thanks for all yer help.

                        Just a follow up- the 1k 2W Ohmite OY102KE resistor is huge... almost an inch.
                        I think it's the smaller 1W OX102KE what is used in the Fluke multimeters? Brymen 867 also uses the 1W part, based on pics.

                            The fusible resistor in the service manual is 2W.

                                    Dell 2209WA - power supply - Fusible Resistor replacement
                                    by jinu_j
                                    Hi

                                    I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.

                                    1. FR950 - blown fusible resistor - 0.2 Ohm 1W
                                    2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
                                    3. R835 - Blown Resistor - 20KOhm SMD resistor
                                    4. D930 - Shorted Schottkey Diode...

                                    Need help to identify and to locate a 0.33 ohms fusible resistor for power supply
                                    by gica69
                                    I have a quad charger that is split into 4 separate sections and one section doesn’t charge anymore. I have located what I think is a thermistor and on the shrink tube it says 125 degrees C. I cut the shrink tube and it's a 33 ohms resistor. It measures a little less than 1/2 inch in length. I am including pictures of it. Please help me identify it. So, it should test at 0.4ohms and probably go up in resistance with the rise in temp. On the board it clearly says R for resistor. But it has to be a special one.
                                    Resistor shows orange range silver gold and green lines.
                                    Thanks in adv...

                                    Is this a fusible resistor?

                                    This is from the power supply of an LED shop light. The light went completely dead suddenly. I removed the SMPS board and it looked really good except for some bad solder joints. I touched all of them up but the light was still dead. I then found this open resistor that was between the neutral wire of the plug and the transformer. The color bands seem non-standard. Does it indicate 13 ohm, 30 ohm...? I am not sure. What should I replace this with?

                                    Need help to replace burned resistor in 350w atx psu
                                    by mikey5791
                                    Hi to all forum members,

                                    Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
                                    The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.

                                    Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
                                    Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor...

                                    Can a resistor lose resistance after hot air?

                                    I am curious if a 0402 resistor could go from 43 ohm to 0. In electronics class and my experience a resistor can degrade and gain resistance all the way up to not being able to conduct at all. I have never heard of a resistor decreasing in resistance and becoming 0 ohm or a dead short… that's not the direction they fail… or so I thought.

                                    I was attempting to remove a wson8 chip on an iMac motherboard and it required a lot of heat, on one side of the chip were 3 0402 resistors that were very close. I popped the chip out unintentionally out of the tweezers and sent those resistors...
