    Wired, rechargeable battery powered overhead LED lights

    . Sir Ian . . . . . . . . It certainly looks like that referenced lighting sources will be adequate , but the only site referencing suggests each unit pulling 3 watts @ 12VDC. Therefore when relating a string of 5's runtime into the use of a Li Ion battery pack would have a battery runtime...

    Need to know pin out (input output voltage ) of an old UPS Transformer

    Sir Prohor . . . . . . . In initially examining the accumulated layer of iron oxide on that one particularly affected E lamination. In its highest level of oxide deposition . . . .as is being verified with a scanning electron microscope . . .is showing right at a 473 micron height. THIS...

    Technics SA-828 Receiver from 70s- Is it worth trying to save this aging patient?

    Confirm . . . . The original batwing power xstrs were bad in the left channel of the unit. Did you lose yet ANOTHER set on your last test ? If yes . . . . Would you like me to give you a procedure, in order to not lose another set on the next power up ? If so, include in your parts order...

    Wiper Motor Wiring

    . Sir darren adcock . . . . . . . I have added onto my earlier # 10 post, so go back and read the final add on, and also . . . . . . a stand alone LM317 just can't handle your motors power/current needs. So o o o o o . . . . . read up on using a companion power transistor in conjunction...

    Wiper Motor Wiring

    . Sir darren adcock . . . . I will just further confirm that a bit of power will be required to run that unit, particularly if taking on a load. I need to use it for single direction continuos (sic) rotation and thought it's be simple enough to wire, THAT aspect has already been...

    Frustratingly familiar connector

    sir tlhonmey . . . . . . . The above should be the male counterpart to what your blurry female connector shows . . . . .as needing a mating male 15 pin SATA connector . . . .take note of the 15 count as they are being redundant for reliability. Just in case you were previously...

    Power up problem in aiwa nsx 330

    Got at least a DVM, ability to disassemble to be able take closeup photos, identify parts . Plus, that is being a complex . . .GOOD SOUNDING . . .unit that they crammed within a small internal area. Its described problem will likelyy be a power supply issue or an overloading power audio...

    Identify Faulty Bulb

    . Sir Muhammad Basit . . . . . Sir Chris . . . . .as per . . . " Use your Ohmmeter instead " . . . . . . . Referring back to the sole forthcoming information provided in posts 1-4 and 6 it just is being perceived that no instrumentation is being had / available and the only reference been...

    Remotely triggering a single button

    Technics SA-828 Receiver from 70s- Is it worth trying to save this aging patient?

    I forgot . . . . it's been so far back, but isn't the problem with the left channel now, and with the right channel still operating properly. If so is there a high probability that the right channel has ALL of its Original Equipment Manufacturer semi conductor devices present, and it if so...

    Having trouble identifying a diode needed for a repair.

    Okay, I have got it now, we ARE in Kansas along with Toto and we are strictly Battery powered (12 dc) NO overhead AC lines to be seen anywhere ! What was being meant by the labeling on the switch was actually being the markings on the panel that it is mounted onto, just above and below the...

    Identify Faulty Bulb

    Now was the PROPER answer having 100 bulbs all unplugged and being in front of you and then using an ohmmeter across each one for individual testing. Or: Sequentially series testing the whole string with an ohmmeter, OR: Use of a 1 1/2 volt cell and two wires to connect to and test each lamp...

    Wi Lite wireless lighting switch

    Unfortunately I work best seeing the other side of the board . . . . But an initial rough analysis seems to be finding AC line input coming in thru the BLUE input surge varistor and then into the 100 ohm film resistor and then into the Gee-iant GREEN polyester film capacitor . To be utilizing...

    Identify Faulty Bulb

    Now on that string of lights, they would all typically add up to your 230VAC voltage when strung up in series, this is not the case when I add them up as 330 V.. Possibly they are running the lamps at undervoltage for better lamp longevity. Here is what I think might be the case in that one of...

    Sir AgTech4020 . . . . . . . Sooooo . . . .this 'pears to be late 1990'sh---- early 2000 vintage piece of equipment. And any 30 amp association would have to be specifically related to the HEAVY heatsinked area. With the three black wires from this units transformer carrying in the reduced AC...

    Need help identifying a component!!!!

    Sir bushtech . . . . . Moving on down to your situation . . . . " Mine is a SM 53 6. " Now, I could only suspect it being the same on THAT part needed. With the 53 being the key numbers and being unsure of the end 6 aspect. IF your unit is not testing out as being SHORTED then use the same...

    Radio Altitude Meter Teardown

    MTSOC . . . . . (Man that's some old crap) Circa 1968 . . . .with the toroid used being the key. I just LOVED to see that bi-directional servo motor drive that series gear train up-and-down in response to the different altitudes . . . .ESPECIALLY on hard dive simulations. 73's de Edd
