Q:Any ideas what th FL5 50 amp fusable link is for, thanks in advance
Give the abs unit a slap with your palm.I had one of thes e with a stuck solenoid causing the unusual current flow What follows is not related to your problem but the info about FL5 follows:- If you have a Range Rover Classic or Discovery 1 that is getting up there in age and has had its share of use, not to mention exposure to western New York winters, you may soon find out how a fusible link works. Sometime in the 1992 Model Year, Land Rover introduced the fusible link as an added protection to the electrical systems in the Range Rover. This system also was used in the Discoverys. If you experience a number of sudden and simultaneous failures of various electrical systems and components, there is a good chance that you have blown one of these fusible links
Q:Hello. I have a Peugeot 306 1.4i (2000). My battery wasn't holding charge and having tested it it became apparent one of the cells was damaged. Having replaced the battery the car still won't start. Prior to replacement of the battery the car had needed jump starting a few times.So when I turn the key to on position the lights on my dash light up. If I try to actually start car power dies. If I try and turn main lights on from this position - power dies. Once the power has died I can turn the key and no lights will come on dash. To get juice round the car again I can wobble the battery and power seems to flow back through car. Possibly there is an issue with battery connectors?I ran a multimeter over the main fuses with the key in on position and all the main fuses in the front have 12v running across them - so fuses good I'd think. This means the starter motor could be gone and draining all power? Maybe?Any ideas / suggestions would be spot on! Cheers.
get new terminals fitted .and as suggested charge battery ,car will start ok with that done .rem to tighten battery terminals well .you said you wiggle them and lights come on . that suggests not tight enough ok .all the best .
Q:If I were to connect an appliance to something other than an electrical wall outlet for power and that device produced more volts / watts than what my appliance needs to work, would it mess it upand if so how to I control this?
if V I R, you are effectively increasing V while keeping R constant; so I through the device must increase. Power dissipated by the device I^2 R : so by doubling the applied voltage, you'd quadruple the power dissipated by the device. If you're lucky and the components can handle the additional heat dissipation requirement, then nothing will happen except the device will become quite hot to the touch. If the components can't handle the additional heat being generated, the device will burn out. If you're lucky, there is a single fuse or component that will burn out and break the circult; stopping the flow of current. If you're not lucky, then the device could continue to heat up and eventually catch fire. you need to buy/acquire/build a voltage converter/power supply -- something that will take the input voltage and current and output the voltage'/current required by the device. Running 12V electronics from a car lighter socket, you encounter this all the time. The DC adapter basically takes the raw 12.6V and ensures that the voltage/current specification required by the device are met.
Q:2.8 manual trans blows ecm b fuse in the under dash fuse box. Changed relays(2), fuel pump and ecm. It might be the fuel pump primer but I don't know where it is located.When I bypass the relay the fuel pump runs but when I try to start the engine while it's bypassed the bypass wire from the positive battery post gets red hot. The engine used to start while wired in this fashion when the fuse would fail. Now the fuse fails all the time.
You have a direct short in the ECM B circuit. When you bypass the fuse you destroy the harness, fuses are to protect the harness and the components they are connected to. They protect the ECM. The B circuit usually is the power circuit for the fuel pump, through the relay. Check the harness for continuity from the relay connector to ground from the fuel pump power supply wire I think it's tan/wht. If there is you have a short and you will need to pinpoint where. but you have probably already melted the harness together. Good luck. It might have been cheaper to hire a professional mechanic shop.
Q:component in the product functioning or not. true or false?
You are attempting to characterize interdependence. Logically, something is independent if it has no dependency on any other component in the product functioning AND SEPARATELY no other component in the product can cause it to function or not. You describe the first component, but not the second. Example - An IPOD plugged into the cigarette lighter of the car (and pretend that it has no internal batteries). There is nothing that can be entered into the ipod that will change how the car works (car is the potentially independent component), however, if the car fuse blows, the IPOD turns off. This certainly violates the hypothesis that the car is independent.
Q:from a circuit board, is this a resistor or a fuse?
Use a volt/ohm meter to test the fuse. Connect leads to each side of the fuse. With power off, measure ohms. Anything other than zero, you need to replace the fuse. or With power on, measure volts. Anything other than zero, you need to replace the fuse.
Q:Hi everybody, I tried asking somebody to check the engine light on my car, they accidentally jumped the wrong cable which seems to have stopped my sony car stereo from working now. I checked the radio fuse and fuse behind the stereo and they all look fine. I am still able to eject and insert a CD into the system so that means that power is getting to it right? Is there a reason why the head unit doesn't come on?also Is it possible to fry your cars wiring with this mistake? But isn't that what the fuses are for? Is it just my head unit?thanks in advance!
No, fuses do not protect against reversed polarity. They are designed to protect from shorted electrical supply wiring and overloads (excessive current). Reversing the DC polarity to many devices will spell sudden death. Depending on how long the condition existed, there could have been a really huge buildup of heat which has damaged power supply components. One reason that reverse polarity is used with DC welding equipment is that normal polarity puts more heat into the workpiece, whereas reversed polarity puts the heat into the welding electrode.
Q:I tried both slow-blow fuses and fast-acting fuses, the fast acting fuses are blown immediately, and the slow blow fuses allow the amp to turn on, but it doesn't work correctly. The amp is a fender personal small amp. How can the amp be fixed?
There's an excess current drain in the amp. A component has failed and needs to be replaced. Replacing the fuse won't be of any help until the amp is repaired. Without technical know-how yourself, you'll need to take the amp to someone that can fix it for you.
Q:Hi, I've had a lot of problems with my bike and I know I need a new one. Don't need to be told that. I own a 2005 R50x 50cc scooter. On my way home, the lights went off and the 'dash' went off including the rpm gauge. The horn, starter and full beam still work though. The fuse is fine and it isn't the battery. If anyone has a clue please let me know and the location of the components that may be affected. FYI, all the electrical bits are in the front not under the seat. Many thanks
Without a wiring diagram, I can only speculate. The ignition switch might have a seperate circuit for the items not working. Using a test light, check for batterry voltage at each component. Trace each wire back to a wire they all have in common. Figure out why that wire isn't getting power.
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!
It could be your time-n-change. A oil change will not stop your car from starting.
