- Q: I have a 24vac about 5 amp transformer that will have leads coming out of it for testing electric circuits. I need to know if there is a component to help me out. If the leads were to touch together it would short out frying my transformer. I need a device that will upon the leads touching will not allow the current to back into the transformer causing a short. I know a fuse accomplishes this but I don't want to keep buying/replacing fuses since they will touch a lot! I'm going to use a resettable circuit breaker for know till I see if there is a better alternative. Thanks!
- Whatever reason you may think you have for doing such a thing, stop it. The output of a transformer cannot be safely shorted, even for a fraction of a second. If you do use a circuit breaker, it will do exactly the same thing as a fuse, except that the circuit breaker should not burn out. If you persist, you will eventually burn the transformer out.
- Q: I have a 24' sylvania color tv that suddenly stopped working. I discovered that the fuse had blown out but when I replaced it with another one it immediately blew again why would that happen? There were no other components plugged in at the time, just the tv alone.
- Because theres something else down the line that made the fuse blow, something shorted. Dont worry most people who replace the fuse happens to them to. Recycle it. or Get it repaired.
- Q: I have a 1000 watt insignia amp trying to power 2 12 sony xplods but everytime i connect power to the amp the fuses blow in it. I also have a fuse by the battery that hasnt blown. Everything is right and it should work, I have gone throught it like 100 times and I cant understand why the fuses are blowing. Someone said insignia is garbage and i should just replace the amp, is this true?
- probably have you tried a larger sized fuse?
- Q: After discovering the reason why my car battery kept dieing, a massive draw on my car battery coming from my IOD (Ignition off Draw) fuse, i was able to start my car reliably once again! However, without this fuse, my turn signals will not work. Is there an easy way to get my turn signals working without having to take out and put back the fuse every time i want to start my car???
- instead of fixing the problem by removing the fuse I would find the actual problem and fix it. Then you could reinstall the fuse and your turn signals would work.
- Q: I'd like to be able to generate significant voltages of DC for experimentation purposes, but so far am having difficulty in creating/sustaining such high voltages. My hope is that the answer may lie in building a voltage multiplier, but I know very little about such technology. It seems I could potentially build one if I knew what components to get and how to configure them. Any help would be appreciated.
- yes, you can use ordinary diodes and caps for this. The difficulty is in adequate separation and insulation between stages. For example, if you start with 120 volts ac, from a simple isolation transformer, you can get 160 volts per stage. You need 400 volt diodes, although I'd get 800 volt ones for extra margin, such as 1N4008, as the price difference is small. For the caps, it depends on the current. I'd get perhaps 20?F caps. You need only 200 volts, but I'd try for 400 volts for extra margin, in case one stage dies. reference has more details. edit: I'd be sure to use lots of fuses, like 1 amp ones. And I'd get some high voltage resistors, so you could build a voltage divider to measure voltages. For example, a 100:1 divider could be a 99 M ohm and 1 M ohm. The 99 M could be 4 - 22 M and 1 - 11M. You may have to adjust the 1 M upwards to compensate for your voltmeter resistance. A thousand to 1 would be a 1 Gohm resistor and a 1 M resistor. You can get the Gohm from places like Victoreen, or build it up from smaller resistors. Note that 1/4 watt resistors usually have a max voltage rating of 450 volts. I have seen web pages that go into detail on how to do this, re epoxy and other techniques to maintain the high voltage. .
- Q: I had my brother wash my car and he put a hose to the engine compartment and by the time i saw him he had wet everything under the hood. I turned the car on and it started/ran just fine, the display was on but all went dark after about 30 seconds or so. Its been 3 days and still dark. What do i do? It has a 5.7 liter 350 V8, TBI.
- definitely, definite, it may bring about failure of the Catalytic Converter. You O2 sensor detects whether finished combustion has took place. with out it, the laptop will deliver extra gasoline than needed and which will overwork your catalytic converter. the main important element you will see with a bad O2 sensor is detrimental gasoline financial gadget.
- Q: I have 5mm LEDs that Im using to make automotive tail lights with and I need to know what I use for surge protection.
- No surge protection is required, and as for fusing, use a normal-blow fuse rated about 20% higher than the current normally drawn by the lights.
- Q: Hello,I am having a home audio problem. I got an amp for free (Tanderg TR-2080) along with 2 BW speakers. I wired it up and worked great for over a year. Then all of a sudden the LH channel suddenly stops working. Thinking it is a disconnected wire, I switch channels and now its the RH side not working. Is there something I should look at, first and foremost? I think the amp is kind of cheap but its in my garage for working on cars. I would like to get both channels running but I don't want to spend $$$ to get it repaired. Any ideas?
- There is a slight chance it might be as simple as a blown fuse. Depending on the design of the amp, there may be a fuse for each channel of the amplifier. They would be located on the back of the unit close to the power cord. If not there, take the cover off of the amp and look inside. Remember to unplug the amp before performing work on it! They would be the cylindrical style fuses.
- Q: I bought a 2003 1.4 Renault Megane for my first car and ended up doing 70 through a huge puddle and ruined my fuse box. I got a new fuse box from a 2004 1.6 Renault megane and put it in my car, but now the car feels like its not getting enough power to the engine, the electronic windows dont work as smoothly and also the window wipers wont go off. What is wrong with my car ?
- would be a defective starter/ solinoid. If it became the alternator, the motor vehicle might initiate the warning lighting fixtures may well be on the sprint all the time and the 1st signes may well be as your utilizing alongside the radio wouold fade out, then the motor vehicle might decrease out and no capability in any respectthen you certainly wait and the battery might get better, and the motor vehicle might restart. yet might only run for a shorter distance. each nighttime you will possibly would desire to recharge the battery and interior the morning the motor vehicle might initiate first time every time. So i think of adjusting the alt became a waist of pennies. perhaps in case you may upload if the motor vehicle actuatly turns over once you place the substantial in and attempt to initiate it. or if each thing is ineffective?, whilst the engine wont initiate- does the radio paintings advantageous?. If it became a gasoline pump i might think of it would turn over and slutter to existence with what's interior the carb/injection gadget
- Q: I have BOSS Bass1500 with 25A fuse hooked onto 8GA 1000W 40A metra kit. Annoyed with low output I bought a 2 way subwoofer crossover SOUNDSTORM SX210. SOUNDSTORM SX210 kit requires a 3A fuse from the battery to crossover.What if I run a 10GA cable to power the crossover through my amplified subwoofer?Also, run the remote wire through the amplified subwoofer to crossover?Doesn't make sense laying 2 power cables running from the battery to 2 different things and 2 separate remote wires from the head unit.What do you guys think?
- For the main power you can use a distribution block that splits the power two ways. just cut the main power wire (with the battery disconnected of course!) and connect them back up again via the d block. then run your 10GA wire from the d block to your crossover. Don't forget to put fuses in between the distribution block and the components though. A 25 amp fuse for the sub and a 3 amp fuse for the crossover. For the remote wire you can simply tap into the one already running to you sub. there are connectors for this that you can buy from any electrics store. Good luck. Ben.
