Q: I wrote to the company and they said they can't (or won't) identify the thermal fuse rating, nor will they tell me where to get one. They told me to just buy a new fryer for $50. I don't want to do that, being that I know the fuse costs $2 (I just replaced on my coffee machine). The numbers on the old one are illegible. If I knew the specific rating, I think I could just scoot down to the local Radio Shack and get a new one, like I did for the coffee maker. I can find no service manual anywhere. I assume the rating has to be at least 450 degrees F, but I want to get some more info before replacing what is essentially a fail-safe protection device. If I get on that is rated to high, I run the risk of severely overheating the unit, and I have teenagers who may use it; too low, and it will blow before the oil gets nearly hot enough to fry my chicken. I know I can make the thing operate without the fuse, but I would like to replace it. Any info?
If the old fuse is open, it did what it was supposed to do. Until the cause is found and repaired it will continue to open when it is used. Take the unit in to a local service center and have it repaired or purchase a new unit. The reason the company will not give you the information you request is a product liability issue. If you install a fuse in a faulty unit and burn down your home they are concerned about an insurance claim. For $50 it is not worth risking your home with a fire and your insurance deductible is probably much higher than $50. All advice on this site is worth what you pay for it and that is the limit of the liability.
Q: Any place I can find a fuse schematic for a 2005 Honda Met 2? My daughter crashed hers and ,as I was cleaning it up looking for damage, I found a fuse loose inside her radiator and I see an empty slot in the fuse box by the battery (which could be normal - I don't know). I'm guessing it'scondition that it has been there for sometime, but there is no way for me to be certain and I also want to ensure all the electrical components work as they should.She bought it used so she has no manual. Is there somewhere I can find out which types/sizes of fuses belong in each slot without buying a $50 manual? I've never had a problem getting this info on a car, but can't find it for a scooter.
The honda dealer parts dept can look up schematic 4 - you
Q: I turned the key once for the electrical components and it worked for a split second then it went dead. Then I tried to jump start it and nothing happened, no clicking or anything. just dead. Then, when I unhooked the jumper cables, there were sparks from the jumper cables which would indicate that the battery isn't dead.
If the jumper cables were still hooked up to the other vehicle, then that is why you got sparks between the two cables. How long did you leave the cables hooked up to your vehicle while the other one was still running? Hook the cables up to a good battery and then to the bad battery. Let it charge for a few minutes and go back and give it another try. If you still don't get anything, then you may have a cable loose somewhere, like between your battery and starter. Could be a solenoid or a relay also.
Q: i'am searching for switches or components that act like breakers but for low currents like 5A.
Quote: or components . . . How about fuses?
Q: i understand you need the battery to get a car started and the spark plugs, but what else is used in a car to get it to start? i ask cause when i try to turn it on sometimes it wont start right away, the battery is fine my sparks are good, but the car still has a hard time starting up.
Well three main things that make a motor run are fuel,air and spark. most cars since the eighties are computer controlled by many sensors constantly sending information to the computer telling it what to do by measuring fuel/air mixture,temp,etc and if a sensor is going bad a check engine light normally comes on. you have to have a diagnostic computer plugged into a terminal inside under your dash to read codes the bad sensor placed to troubleshoot the problem. now if no light has come on then it could just be a number of things to do with a tune-up,such as air filter,spark plugs and wires to them or fuel filter.and that's all i know to tell u
Q: I had the fuse break on a Joker 200 light, but I don't know what could cause a surge of electricity (no lightning storm at the time). If it matters, it could have been on the same line as a coffee maker/toaster/microwave. Please help me out. Thanks!
A surge is not going to blow a fuse IN a ballast. A fuse will blow when there is too much current flowing - which might be a loose wire touching ground or two wires shorting. If the fuse is in the fuse box then something else being on the circuit might blow the fuse.
Q: Compare the energy given off per gram of reactant for each of these processes:(A) deuterium (2.01355) fuses with a hydrogen nucleus (1.00728) to produce helium-3 (3.01550)(B) two helium-3 (3.01550) atoms combine to form an alpha particle (4.00150) and two protons (1.00728).I'm not really sure how to go about doing this, I know you are supposed to use the formula emc^2 but I really dont know from there. And i found these answers but idk if they are right and i cant get them. a) E 1.59 x 108 kJ b) E 1.34 x 109 kJ Please explain
The mass you use in Emc^2 is the difference in mass between the fused atom and it's components. For example in (A) your mass (that is converted to energy) is 3.01550 - (2.01355+1.00728) 0 If you want to know why then look up mass defect
Q: a 75kv 750mA fuse has blown in my micowave (sanyo em d953)do these blow because of the age of the machine or is there another reason
The fuse can blow from a power surge, caused by lightning or inconsistent power service. They can also blow from a direct short in one of the other components. Replace the fuse, they are cheap. If it blows again right away, you probably have a direct short in the microwave.
Q: I have an 04 ford focus. My car died after stopping it for about 5 minutes. Tried jumping it twiceonce with old cords, and again with new ones. Oh andI reversed the polarity by accident the 2nd time.I never noticed any signs of my battery dying before this occurrence. I replaced my battery myself and now my radio will not turn on. No other problems, all other lights, brake lights, blinkers, wipers, and auto locks still work. What could have happened? I checked all the fuses, and could see that they were still intactdo I need a new radio/cd player?HELP!~music-less in tx :[
If you pull the radio out of the dash a little way,there is usually an inline fuse on the hot wire going into radio.I doubt you ruined your radio.You more than likely blew the fuse in the line.
Q: car radio
A fuse's purpose is to protect the electrical source of the head unit. If too much current goes through a fuse, it blows but saves other electrical components from damage.
