    Rating of circuit breaker for protection.

    Assuming this is an AI response it doesn't exactly fill one with the 'dread' we're supposed to feel - moreover it makes me 'sad' that it can't even get something so basic as circuit breaker ratings correct. Dumb as a rock.

    You could do many other people a favour by posting a pdf copy on this site - it also gives the site some 'advertising' when people search for this manual as Google will flash up this thread as a result.

    How to detect actuator feedback voltage using Arduino/esp32?

    Connect two resistors (in series) between the blue wire and ground. 'Top' resistor should be five times the value of the lower resistor (i.e. if you use 10k for the bottom resistor, use 50k (or 47k as the nearest standard value) for the top resistor). The voltage between the junction of the...

    You forgot this bit......

    Usually, with transistors of that particular type (body package shape) the pinouts are mis-noted, mis-read, mis-used etc resulting in incorrect connection. Do you have the datasheet for the transistor?

    That's not correct. Short the blue wire to the black wire(s) to enable the 12V output. Leave the red wire disconnected (and insulated). Make sure you have a short wire loop connected from the +12V of the amplifier to the REM terminal too or the amp won't switch on.

    Have you tried to use it with them disconnected? Show us a link to this 'instructional video'.

    Separate them. Insulate them individually. The fact that they are shorted is causing the 'wooping' issue.

    Rating of circuit breaker for protection.

    I sent a 'faux' circuit breaker to BigClive (Youtube) some time ago and the video proved quite popular!

    Rating of circuit breaker for protection.

    More than the rating of the breaker is the rating of the CABLE being used to connect things. The breaker must NEVER exceed the rating of the cable - which itself is dependent on current and length - else you're claiming on your fire insurance. The other importance of that breaker is that it is...

    PROMAX AE-566

    @Promax22 posted their response some 5 months ago, made ONE contribution to the forum (that post) and hasn't been back since. The chances of a response from them is close to zero.

    Tv oled not turn on

    Not from the description you are giving...... What chip would that be? Which terminal? Generic in-house code. Chance of obtaining details of which is ..... 0 Most TV switch-on faults lie with dry capacitors that often manifest themselves as swollen or leaking (sometimes showing no external...

    Altering sensors of similar sort...

    0% Those devices each transmit on a different frequency (channel) so if you fitted a different sensor it would still try to transmit to a channel already in use and you get a conflict whereby (likely) neither unit works.

    My subwoofer is making a thundering noise, can anyone help?

    I suspect he's shorted the 5VStby supply (red/blue wires) causing the SMPS to cycle a fault status.

    My subwoofer is making a thundering noise, can anyone help?

    What did you do with the red/blue wires from the power pack? If they are shorted you'll get 'issues'. Similarly, to get the full amperage from the Power Pack you must use ALL the yellow wires into the 12V feed of the amp - fit a shorting link between the +12V input and the centre pin. By not...

    Burnt resistor’s value for MAS830L multimeter

    Two 0.15ohm resistors in parallel equals 0.075ohms and at 10A will drop 0.75V which just happens to be the amount necessary to forward conduct a transistor junction (to 'switch' something or just indicated an overload situation for example)

    Scratching My Head w/ Crown CDi 4000

    Measured both ways? If so then test again with either of the zeners removed (D28/D29) and again with D26 removed.

    Scratching My Head w/ Crown CDi 4000

    The only way you can get '0V' at TP31 is with a shorted zener or a shorted C196. You said "no luck" with the C196 answer but never told us what you did. Did you actually replace it? Did you replace it correctly or test it before fitting the new part? Have you retested it? That said, a...
