    Scratching My Head w/ Crown CDi 4000

    Still getting 0V at TP31?

    Scratching My Head w/ Crown CDi 4000

    We actually have lives to live and can't dedicate to this forum 24/7 as a result..... If you have DC at the main bridge (I'm assuming a 120V input?) then 0V measured at the top of the zeners (TP31) then resistors R370-373 must be open. What do you measure at the 'top' of R370/R372?

    Thermal Printer not feeding paper

    The MOSFET may indeed be the switching component of the power supply to derive the 5V supply the rest of the circuitry needs. Difficult to tell from the images currently available to me. If you look up the data sheet for any of the other multi-pin devices you may find one that shows the power...

    Over current /short circuit protection for the battery bank.

    Fuses protect the wiring - ensure your cables are rated to carry the 100A. It would be far more practical to fit a resettable fuse/circuit breaker so you can get both protection and the ability to isolate the source voltage in the event of servicing or other issues. The marine market is the...

    Thermal Printer not feeding paper

    The 24V input will use the 24V for the motors but reduce the 24V to 5V (or maybe 3.3V) for the electronics side. Sadly, if there is any issue with the 5V (or 3.3V) side of things you're unlikely to affect any repairs without some sophisticated test equipment and (probably) some dedicated...

    What is the optimal design for loop antenna made of copper stiff wire to transmit at 81.39–90.00 kHz?

    I'm an avid fan of sci fi (have you read Ian M Banks?) and strongly believe that given the resources and motivation that man can overcome 'any' fate bestowed him. Most scifi deals with a future where politics is less of an intrusion in the lives of ordinary people, in fact IMB writes about a...

    Summary: fears of man made global warming, CO2 as a pollutant, ending of fossil fuels and climate Armageddon are all BS.

    Thermal Printer not feeding paper

    Pretty meaningless without some context i.e. where is that MOSFET?, what does it control? A 'short' will read '0' both on continuity and on voltage so reading 'something' doesn't mean a short per se. Now that is a proper symptom! and potentially an issue with the power supply. Show more...

    Thermal Printer not feeding paper

    What level of 'not working'? The subject title infers a simple refusal to feed the paper? Is it just that or more? Have you checked the obvious - correct paper feed, paper type, cleaned the rollers, cleaned the sensors, checked the manual feed etc? After that you could measure the voltage on...

    How about hot steam for unsoldering (more effective than heat gun?)

    Does the OP realise the energy cost perspective of using super-heated steam?

    Oil is said to be abiotic(?) and we've not explored or mined so much as a minuscule fraction of the earths resources. Oil is the second most abundant liquid on this planet after water. If we can get over the ridiculous assumption that using such resources is detrimental to all and sundry we...

    Need help with drum module hiss and clicks

    Most likely from the digital board - use shielded cable for the audio between each board and separate the digital board from the other circuitry (distance). Each board seems to have the relevant decoupling but extra capacitance (10nF or 100nF on the supply lines) wouldn't go amiss.

    In a political sense you could be correct but if you're referring to the climate, environment etc you're wide of the mark.

    What is the optimal design for loop antenna made of copper stiff wire to transmit at 81.39–90.00 kHz?

    1 ton of oil equates to around 11.6MW of electrical energy. An average size freighter (global freighters average 50,000 grt) will consumer 100-120 tons of oil per day. The electrical equivalent would require batteries to deliver over 1GW per day (equal to 50MWhr - EVERY HOUR - and that's only...
