Q:whats wrong with my guitar amp?
It could be the the power supply (that provided power to the tubes) is not working. Just because the low voltage filaments are getting power and lighting up doesn't mean that the high voltage portions of the tubes are getting power.
Q:please help! Odometer and Speedometer question?
get the speedometer working and the odometer will start working.
Q:My car won't start!!!?
i'm guessing that you are talking about the fuse for the fuel pump two things can cause the fuse to blow. bad fuel pump, or a short in the wiring.
Q:ford galaxy issues, fuses, relay if there are any, electrical.?
Ford Galaxy Electrical Problems
Q:General Physics question about electrical components?
Because the fuse is supposed to just create a short circuit when the current is larger than what it's supposed to be. the fuse must conduct therefore it won't have a large resistance whereas a resistor such as a light bulb or any other load is clearly to have high resistance, as the name resistor indicates.
Q:What is the blood component to these functions?
Protection Against Disease Blood Component
Q:do i have to replace the whole part in a 1997 ford thunderbird back lights and blinkers?
Either the turn signal switch or turn signal relay. If the green light comes on when you put the lever in the turn position, check for burned out bulbs, front and rear. If the bulbs are OK, replace the flasher relay. Master tech 40 yrs.
Q:why did my blinkers, brake light, and gauges stop working on my kawasaki kz1000?
Because it spent all that time in the ocean after the tsunami
Q:please help me to get a block, schematic diagrams for +/- 15V basic power supply With less than 15 Components?
you opt for a voltage regulator, amperage concerns much less subsequently. I make uncomplicated circuits and for all people I upload a voltage regulator. considering which you're working at a extra physically powerful voltage, you're above my sort (i take advantage of 6v and below). in spite of the incontrovertible fact that, maximum high quality voltage regulators comprise geared up in cutting-edge and voltage secure practices. A voltage regulator additionally will modify the present to a particular output. verify the link below, 5 amps max (thats solid on your case). The voltage is likewise in the skill, dont be perplexed by way of the information sheet. that's unquestionably fairly user-friendly. You DO choose a multi-meter to purpose the outputs in basic terms incase. yet that would desire to do it for you guy. i'm unfamiliar with the kind of regulator I appropriate in spite of the incontrovertible fact that it is going to tolerate warmth effective judging by way of its layout and schematics, not a low priced little 1cm x1cm element. this might set you back approximately 5-12 greenbacks. based the place you purchase it, choose a soldering iron and additionally the multi meter. something with DC, i like to characteristic a diode for a circuit, stops cutting-edge/voltage from going the incorrect way. Your capacity supply might have it regular although. Edit: in spite of if that's RATED for 10 amps, it does not advise that it is going to likely be 10 amps, relies upon on the draw. Thats all it may produce. Odds are you have a low priced duel factor fuse in there. it is going to hold a solid 12 amps for 15-20 min. Volts will burn out circuits quicker than amps (yours is possibly rated for 600v), so verify that score first. As an electrician, we continuously verify volts first. OCPD (overcurrent secure practices gadget) will cease any injury. You DO choose a regulator although, to guard your amp. Edit back: Jumbilia kinda reaffirmed it. Love electric engineers!
Q:What's the most common component effected by electrical surges?
Typically the power supply. Sometimes as simple as a blown fuse, other times it can wreck the transformer, bridge, regulation circuits and of course resistors etc. Check fuses first.
