    Repair of Dewalt dcb101 battery charger

    Sir suppala . . . . . . . . That charger can be a real problem if one cell drops out or will not charge. I took out the battery and connected + ve and - ve terminals of battery with +ve and -ve terminals of charger and succeeded in charging the battery. If you are able to get access to...

    I need help identifying an SMD capacitor and ordering 2 axial inductors

    Sir jacob varley . . . . . Just a ton of additional . . . . . . "NOW I know why it did that " . . . . . . facts now coming forth. (meaning it emitted RF and the old inductors didn't get hot) and the only use of ((( that))) cap was for RF filtering - your thoughts? Nope . . . . the best...

    DT 9205A Help

    Sir memo_memo. . . . . . . Of its many clones . . . .I wonder what brand name your unit has on it ? From your problems description, there is a high probability that your unit has DOUBLE POLE- DOUBLE THROW switch inside which has lost contact tensioning or has oxidized and is no longer...

    I need help identifying an SMD capacitor and ordering 2 axial inductors

    Sir jacob varle . . . . . . . . Ahhhhhhhhh so . . . . . . this do be velly- velly intelesting . . . . Rather than a further observational manner, instead lets move more of an analysis of what we currently have. Figure on our DC power coming in from the shown VERY nearby power connector and...

    Fix Satellite Dish Positioner

    That actuator certainly was CLEAN inside. While you are at it why don't you try a RED LED across the actuator terninals, tried with both polarities, to see if it has enough current to drive the LED as a test indicator.

    Need information about diode VDAG01AT

    PIV spec ? Current spec ? Schottkey ? fast diode with nanoseconds spec ? All I can tell you is that they are available at Panasonic or Encompass parts.

    How to test a transmitter circuit?

    Sir Teh . . . . . Is your monitoring receiver old school, that lets you tune to any frequency and thereby be able to receive white noise / hiss when tuned off of a station, to a dead spot on the FM band ?. Or is it digitized and will step to and stop on ONLY active received stations ? Old...

    Help On Relays

    Sir emyel2697 . . . . . Inspect your unit and see if it is having a mechanical relay inside for doing the light switching. If so, then check the number of large power switching contacts being on the relay. Could be 2,3,4 or 6. HOPEFULLY it might be a SPDT (3 contacts) or DPDT (6 contacts) type...

    Pipe Locator

    Sir zamiac . . . . . . . . A couple more probing questions while we still have you here on the 'ole Interweb . . . . FIO . . .That unit can be used in either a conductive mode or an inductive mode. Are you exclusively using one mode or do you switch, and if so . . . . . is your problem...

    Fix Satellite Dish Positioner

    Sir pharaon . . . . . . . . If your short passage there says that the dish was able to be moved, prior, with the sensor wires connected, but now with them disconnected for testing, the dish wil not move. That seems to tell us that we DO have sensor loop wiring continuity, which was being our...

    Fix Satellite Dish Positioner

    Sir Pharaon . . . . . Since I still do not know product brand nor specific model, I will just engage in concept of design. With both of these sensor input connections being black, I then can possibly assume that this uses the simplest methods of detection of rotation of the actuator. We had...

    Fix Satellite Dish Positioner

    Sir pharaon . . . . . . . . OK on the first top photo I can see the rear RED and Black connectors that feed drive power to the activator and MOLEX CN1 with its 4 connections on the PCB, where the units remoted power transformer is inputting its AC power into the board. What I am NOT...

    Ways To Turn Knob With Stepper Motor Using Arduino

    Sir StealthRT . . . . . Could you work with using one of these with pulsed DC drive ? To fine tune in its speed aspect, as it's going to have plenty of torque. Or use one extra gear down set in interfacing into the knob...

    Two mic's, one CB

    Sir Chando . . . . . . . . I have chopped down a “ thousand large trees and extracted 66 tons of massive boulders “ in order to then simplify the complexity of your units schematic that you so generously provided me . . . . and now . . . . we have come down to only its sole circuitry being...

    Samsung TV

    Sir rutwad. . . . . . . . Why . . .'soitanly . . . . It’s just that I am edu-guessing that Samsung might have initially had their power supply design prototype and then jobbed it out to be manufactured by 2 or 3 other firms / closet subsidiaries. OR they might have just loosely given out...

    Restoring a Regal Do-Wa-Diddy by fOXX

    Sir tedstruk . . . . . . . . Just examine your unit as it is presently wired and tell me what ancillary remoted component you have the wire from PCB stake A going to. Also, I have need to know . . . .within the expanse of a COSMIC / NATO / CRYPTO / TOP SECRET / EFTO clearance . . . . ...

    Correct name for push button switch

    Sir Tyler Monk . . . . . . . . Lets now compare and evaluate and see egg-zackly what switch action you need. From what can I perceive from your initial given information of : Be momentary, no latching That is where the spring loaded comes into play . . . . it only engages . . . for...

    Trying to repair our VFD

    3.6 kb density won't cut it on that photo. If using Cmos circuity in that area, are you sure that water hasn't seeped and creeped and is still having moisture / wetness hidden? Try a heating of the potentially affected area with a blow dryer 73's de Edd
