    How to test this 24v 13" Worx Mower

    I couldn't fathom the images you posted - until now! Now that I 'see' what you've done you say you aren't measuring anything across the terminals where the genuine battery should connect? Is that with the switch in the run position? If so then maybe the switch is defective or the motor is...

    Tv oled not turn on

    Google the make/model and see if there are standard repair kits for the PSU section as, if such faults are commonplace, kits are often readily available and supply all the parts necessary to get the PSU working again. Alternatively use eBay or other source to find a replacement board.

    Kitchenaid KBMS1454SSS-3 Microwave control board troubleshoot & repair

    The technical document says the MW transformer section is replaced by a inverter. Clearly the inverter is faulty. Show the inverter board (both sides). Alternatively, disconnect the power TO the inverter board and test to see if the unit will power up. If so then the inverter board is dud or...

    How to test this 24v 13" Worx Mower

    Meaningless. Show where you made a measurement, how you did it and the results you got. A 24V device won't work with an 18V battery. At best it will cause an over-current situation and the built-in battery protection would cut off the power from the battery anyway. The battery terminals may...

    Cause for TX frequency difference

    The crystal is probably associated with two capacitors and you can - if necessary - replace one of the capacitors with a variable type and trim the oscillator frequency using it.

    Repair to Control Board PCB of Whirlpool Oven

    The display CAN be levered up if you can separate the sticky pad - a sliver of something 'sharp' can be used else just trial and error, hoping the 'error' side of the equation isn't destructive! Heating the board with a hot air gun often works to loosen the glue too. The board can take a...

    Repair to Control Board PCB of Whirlpool Oven

    Sure about that? Which IC is it? There are no ICs under that board as far as I can tell. They'd have to be surface-mount if they were and the replacement part isn't that type. It's possible to cut the leads of the ICs close to the body of the IC (craft knife) leaving the pins in the board...

    Kitchenaid KBMS1454SSS-3 Microwave control board troubleshoot & repair

    Inevitably as a result of overload somewhere. Disconnect the connections to the off-board items (magnetron etc) and see if the clicking stops. If it does then you need a new magnetron.

    Need help w/ home stereo

    As said, that plug is a Chinese 'killer' plug being un-fused and, most likely, aluminium cored wire instead of copper. Totally illegal in the UK. But the main issue is the cut-off mains cable. That usually indicates the equipment is dud/faulty. A replacement will involve opening the set and...

    PWM on 12volt winch?

    A pot won't work. PWM does lower the voltage (average power) so there's that. And your winch doesn't do 10.5/s - that's like snapping an elastic band. Maybe 10.5m/MINUTE. (approx 2 feet/sec).

    PWM on 12volt winch?

    Personally I'd use a 100A device (with suitable thermal/overcurrent trip, resettable) and be careful how I used it. I'd also use a bypass switch to run it at full current when that was necessary - probably not very often. Even a low current controller can be modified to work at MUCH higher...

    PWM on 12volt winch?

    The x5 would only apply to 'dodgy' source units. As per Bluejets saying 'quality' product, such a device would work when rated at 250A or even 200A with suitable fusing/breaker for protection.

    PWM on 12volt winch?

    Spec says it's a permanent magnet motor. Full pull current is 200A at 12V.

    PWM on 12volt winch?

    Strongly doubt that the winch uses a BDLC motor. If its original control was a simple on-off switch (or push button) then it's a brushed motor and PWM controllers are 'ten-a-penny'. Bluejets mentions the key word 'quality' - under this meaning I would agree that the 10-a-penny devices should...

    Trying to identify a resistor network

    '102' signifies 1k ohm so replacing the package with 4-off 1k resistors (1/8th watt) would be easy enough. Solder four to the pads in the elongated rectangle PCB marking, fold over the opt wires of all the resistors and solder them to the single 'pad'.

    Help to identify/replace component

    What the motor consumes and what the semiconductor is rated for are often not comparable. I can't imagine that because the motor draws 12A the designer would spec a 15A MOSFET. Coould be that they got a good deal on 162A MOSFETS and that's the only reason such a rated device is fitted but, to...

    What are specs on this cap?

    My bad. NOT a typo in that context - that's what I meant when I said 20/22, sorry. What is the voltage at 20/21 with power ON? What is the voltage at 20/21 with the START button pressed? That 2.5VAC is 'as good as nothing' so with nothing on the rectifier ZL2 there should be NO DC coming out...

    PWM on 12volt winch?

    Lots of 12V PWM controllers on Ebay. If yours is a 'brushed' motor then there's loads of solutions.
