- Q: I own a 21.5' Spectrum sail boat I
- any of the books by Nigel Calder will give you the details on proper marine wiring. I suspect your boat was made in the 1970's or 80's and the wiring is not adequate for today's safety standards. The number of fuses depends on the accessories you have. And you want to be sure to fuse each major accessory e.g. bilge on one, radio on one, navigation lights on one,
- Q: i have a cb base on my home i was connectin the cb on my power supply and i put the wired rong i switch the way is supost to go and know the power swich goes on the cb wont go on i check fuse on power supply its good and radio is good in the fron of the power supply i have 2 button for positive and negative i think the problem is there fuse never burnplease help my question thank you god bless you
- Does the power cord coming from the cb radio have a fuse? if so, it is probably blown. If it does not, then you may have fried a diod or other component on the cb radio circuit board.
- Q: I have a video mixer here which the power plug says 12v 300mA and i have a power supply which is 12v 1700mA. Will i be able to use this power supply or will it blow the video mixer up? Thanks
- You have a power supply with about 5 times the power requirement of the mixer. You can very safely use that power supply, the mixer will only take the 300ma that is needs. The higher capability of the power supply is idling(not used). In actuality you can run 5 mixers !!!!!!
- 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.
- Basically everything under the hood is necessary to start the car. Air filter, oil, battery, ignitions, ECU, fuel, fuel injector, pistons, valves, crank case, crank shaft, spark plug, wires, etc. You would have to ask more specific question and describe your problem more specifically. Good Luck.
- Q: Hey i just bought a van for travling and i was wondering what can i run off a 12 volt power point?? kettle ' fan ect.
- you should be able to run anything that does not exceed the amperage rating of the fuse for the power point this is usually about 10-15 amps, depending on the vehicle and what other components this fuse controls. If we consider that wattsvoltage x current that means that you should be fine with anything that is rated at under 120-180 watts or a combination of things (using a splitter) totaling less than that. Find the fuse that controls your power power point, and look at its amperage rating. I would assume that this fuse also controls other components as well (dome lights, etc.). Multiply its amperage by twleve and that is the MAXIMUM number of watts that can be used on that circuit. Since this represents the maximum number of amps possible on the circuit (and probably would result in a blown fuse) dont pick an appliance that matches the wattage number you calculate or you will overload the circuit and blow a fuse. Other than that you can use just about anything that meets these requirements.
- Q: car will not start, could it be some thing to do with time for oil change. Have new starter andd battery. Still can not turn motor over. Turn key loud clicking from fuse box under seat!
- That's what you get when you buy an American Tuna Boat.
- Q: Hi my first visitI have been having problems with battery drains lately. Overnight the voltage of my car battery drops from 12.4 to 11.8 and if I leave it more than 3 days it will not start (11.5 to 11.2). On idle and load it is near 14.2. So I feel alternator is charging well.I am about to start pulling fuses to locate drain but was wondering if an alternator that is starting to die (but will still charge) can cause battery drain. Can the diodes in alternators draw current from the battery?Thanks
- Yes, it's possible that a marginal diode can cause battery drain. I think your idea of pulling fuses is a good idea. Connect a meter to to the battery to measure current, determine how much draw there is, then start pulling fuses, one at a time. Note that stereos with clocks will always draw some power, as will an alarm system. Be careful what you disconnect, since some alarm systems need a complete reset if power is lost. The ignition / fuel management systems on some vehicles are also affected by power loss. Check your owner's manual first!
- Q: I am looking to short out a resistor - any way I can actually short one out so that it is faulty of its own. Also, any ideas if i can blow one so it is open or is the fact it ends up being shorted or open a random thing that when it is bad it just so happens to be one or the other, not that certain conditions produce one and other conditions produce the other.Any insight into this is very helpfull. Oh, I know about use the jumper wire to reproduce a shorted component I was hoping to actually use a damaged component and I do not have one right now. Thank You Kindly One and All(this is not a school related lesson, I am trying to teach myself at home - I'm an adult learner).
- there are many kinds of resistors. fixed carbon resistors have a wattage rating. if you exceed the wattage (may be dangerous) the resistor will heat up excessively and burn. it stops burning when it is physically broken and cannot continue to conduct electricity (or blows the fuse). this then creates an open circuit. open circuits are commonly misnamed short circuits. a short circuit happens when the electricity in a circuit takes a shorter (or different) path than the circuit was designed. this may burn out a circuit component, then you will have an open circuit. does this make sense?
- Q: I have a 2003 Hyundai Sonata and the power locks in it won't work. At first I thought it was the key but the unlock button works. The lock button doesn't work in neither the car not the remote. Is it just a bad fuse or is it more complicated than that?
- The owners manual will give you a list of the fuses and what they opperate. It would be unusual to have the fuse to the lock mechanism be different than the un-lock fuse. There must be a universal lock component somewhere that is the culprit. Could be a loose connection , burned wire or a short. I wouldn't know where this component would be on a sonanta. You would need a Haynes or other repair manual to know where this component would be.
- Q: I did this hardware mod for my computer : (
- Two things seem likely. 1. You've created a short circuit somewhere 2. Your mod is trying to draw more current than your power supply can provide
