Car Electronics and Lights

The formula you are looking for is W = A x V.

GPS receivers integrate a radio and a navigation computer and can receive the faint, twenty-watt signals coming from the satellites. The computer uses these signals to calculate the distance between the satellites and the receiver. With this information, the computer can further calculate the position and velocity of the receiver.

The number of satellites visible to a receiver constantly varies between four and eleven according to time and location. Each satellite broadcasts a number of unique spread-spectrum codes, but only one, the Coarse Acquisition (C/A) code, is easily accessible for civilian use.

On the ground all GPS receivers have an almanac programmed into their computers that tells them where in the sky each satellite is, moment by moment.

It depends on the fixture. I have 4 types. One has screws on the outside of the metal frame, so you unscrew those and hold the glass bowl. Another has two big metal clips INSIDE the glass bowl. I have to be brave and just pull to one side until the first side unclips - putting it back on is more nerve wracking! Another has a metal pole coming through the center of the dome. Hold on to the glass, but pull the metal piece a bit to one side and then unscrew it. The final one almost stumped me - an electrician purchased it and installed it this winter and I never thought about changing the bulb! There is no metal pole, no screws, just the frame and the dome. You have to TWIST the glass counterclockwise and it unscrews (there are three metal bumps on the INSIDE that hold it when you screw it back. hope this helps!

And I found a fifth: Hold metal frame and pull down on glass fixture. One side started coming out giving me confidence to pull more. I finally removed the glass and found three Spring Clips that hold the glass fixture. I strongly suggest that this is the last method you consider.

To program a new sliding gate remote rc434, you typically need to follow the manufacturer's instructions. This may involve locating the programming button on the gate system and the remote, and then pressing them in a specific sequence to sync the remote with the gate. Consult the user manual or contact the manufacturer for detailed programming instructions.

Old-fashioned camera light bulbs could burst due to a variety of reasons, such as excess heat buildup inside the bulb, manufacturing defects, or physical damage to the bulb. The intense heat generated by the bulb during use could cause the glass to expand and contract rapidly, leading to its eventual failure.

Yes, lead can conduct electricity, but it is a poor conductor compared to other metals like copper or aluminum. Lead is used in a variety of applications for its electrical conductivity properties, such as in soldering materials and electrical cables.

real P= V * I *cos(phase angle between V and I)
for purely resistive loads or DC voltages this equals real power P=V*I = 120*5= 600Watts
for not pure resistive loads you'd have to measure the phase angle between Voltage and Current to get real power.
However, at home, the utility company charges for Complex power = V*I.
So you'd still pay for V*I.

To wire a three-way switch with SPDT switches for one light controlled by two switches, you will need to connect the common terminal of one switch to the hot wire coming from the power source, connect the common terminal of the other switch to the light fixture, and connect the two remaining terminals of the switches together with one wire. This configuration allows either switch to control the light. Be sure to follow proper wiring techniques and safety precautions.

It sounds like there could be an issue with the alternator or the electrical system in your car. The drop in idle speed and juddering indicate a potential problem with the engine. The flickering interior lights and headlights suggest an issue with the alternator not properly charging the battery. It's best to have a mechanic inspect and diagnose the specific cause to address the problem correctly.

The PassTime device itself should not ruin your car. However, improper installation or tampering with the device could potentially lead to issues. It's important to follow the manufacturer's instructions and have the device installed by a professional to avoid any damage to your car.

Amperage is always measured with the guage in series with the hot wire. That is the one wire is cut and the guage goes in line as opposed to some devices which have a hot and neutral (or ground).

A feeler gauge is typically used to measure dynamic valve clearance in internal combustion engines. The gauge is inserted between the valve stem and the rocker arm to determine the correct clearance while the engine is running.

It is not possible to convert watts directly to volts because they are two different units measuring different aspects of electricity: watts measure power, while volts measure electrical potential difference. So, there is no definite conversion between the two.

dont know -------------------------------- EDIT: 2 Channel if really what its sounds like, 2 channels which means you have a Left + Right basically. 4 Channels is for 4 channels which like in a car would be Front Left + Right and Rear Left + Right. Reminder!!! Check RMS NOT max Power!!! -TheRamMan-

This is your coolant level sensor or the radiator warning light. It most likely means you're coolant level is low. Check the coolant exopansion tank located on the left side under the hood on the V70. You can add straight water. Don't add just any anti-freeze, light green Prestone; it can really damage the radiator. Volvos are funny that way, a qualified Volvo mechanic knows this. KJR

Yes, they are an efficient way of sorting and transferring metals.

The trip odometer switch on the odometer itself is the dimmer on Toyota Sienna. If you turn this switch all the way to the left your panel would become dark. Simply turn the switch to the right and all panel lights would come on. I had a similar problem and the manual bailed me out.

There is a small rectangular slot on the right side (passenger side) of the transparent cover/lens. Put a properly fitting (not too small, not too big) flat screwdriver in the slot and leverage the cover/lens downward. It should pop out. Don’t be too rough, but you can apply some force—the cover is fairly strong. After that it is easy to pull the light bulb from between the spring terminals. Put the new bulb in and pop the cover back in its slot.

just so you know, all trucks used to have a full 24 volt system and cars had a 6 volt system so the design is not a nightmare. still a lot of tractors about with a 6 volt system. now a good electrician can connect a 12 volt unit to a 24 volt system if he knows what he is doing it is just a matter of knowing where to do it on a battery. you can also buy a voltage converter and wire it in. and yes you can still buy 24 light bulbs Before you go deep inside this, check the voltage on the cigarette lighter. It should only be 12 volts. The 24 volts are used in starting the truck only. By thinking this through, designing a vehicle that worked on a 24-volt electrical system would be a disaster. No one would buy it. All the current electrical components for vehicles are for 12-volt systems. Lights, gauges, radios - everything! How much trouble would it be to replace something like, say, a map light if a 24-volt lamp had to be located? Alternativley Check the powercable as many of them can work on different voltage say from 10 to 30 volts and power the gps with the correct voltage.

The negative battery cable bolts to your engine block and body/chassis of the vehicle. Which means that any metal part of the car is essentially the negative terminal of the battery so whenever you need to ground or earth something on a vehicle you simply find a bolt, nut or screw attached to a metal part of the vehicle and attach the wire to it.

if the ground is from your old stereo either follow it and ground you new stereo there or wire them together uses heat connectors. better yet buy a wiring harness and don't worry about the whole mess.

Everyone should have a manual for their vehicle, and the library should have a professional shop manual available, for FREE, in the reference section(make copies of the correct sections) read up and fix it like a PRO! :) good luck-Dave

A slower blinking turn signal can be an indication that a bulb is starting to fail or has already burnt out. It could also be caused by a faulty flasher relay. Check the bulbs to see if any are not working, and if the bulbs are all functional, consider replacing the flasher relay.

Defective clock or it is wired incorrectly. Should be wired to have power when ignition is turned off. it sounds to me that the constant live has been lost to the clock, there are three wires to a vehicle clock, an earth, an ignition live and a constant live

If the lights still won't turn on after replacing the light switch, check the circuit breaker to ensure it hasn't tripped. You can also inspect the wiring for any loose connections or faults. If these steps don't solve the issue, it may be best to consult a professional electrician to diagnose and fix the problem safely.

Often a fast-flashing turn indicator (inside the car) means either the front or rear turn signal bulb is burned out. Check the actual turn signals and see if they are working. If not, just replace the bulb.
