What would cause a right signal light not to work on the front and rear even in the hazard mode?
Hey Greg==Ther e can be a coulple of causes. one, the turn signal switch or the lights don't have a good ground. Check it out. GoodluckJoe
Thank you for the reply Joe.
I pulled the flasher relay apart and the Mazda has two relays and a circuit board inside. Both relays appeared to work fine, but no right side signal lights. I squeezed the circuit board together and ...voila,signals. I am thinking it is a crack in the circuit board of the flasher. Even though the flasher is $80.00 Canadian, at least it isn't the wiring.
Thanks Again Greg
Depends on the impedance of each speaker. If they are car subs and not converted home speakers, they are probably 4 Ohms each. Depending on how you wire them you get either 8 Ohms or 2 Ohms. 8 Ohms is not a problem load-wise for the amp, but if it is rated at 100 watts into 4 Ohms, then you will only get 50 watts into 8. Many car subs nowadays will handle a 2-Ohm load, but some will not. Your two speakers will handle 2x150 watts or 300 watts. An amp that is rated to drive 300 watts into 4 ohms will either deliver more like 500 watts into 2 Ohms, or it will melt through the floor of your car. So you need to look up the specs for your amp in the instruction manual. If it will only run into a 4-Ohm load, you can only use one 4-Ohm sub per channel. If it will handle a 2-Ohm load, you will have to turn it up slowly or you will blow your speakers out. Mr Ohm and his law will not be denied.
Why is one of your civic 97 Ex low beam not working but high beam works fine?
Low beam bulb is burnt out. Replace it.
How do you expect anyone to answer this goofy question? Actually, it's not even a question, it's a statement with a question mark after it. If you're serious about getting an answer, state what your problem is and the year, make, and model of your vehicle.
Why would the AC and turn signals work when the engine is off but not when it is running?
Most likely is a bad ignition switch.
Do anyone have a Viper 160 xv installation manual?
YES! I have one. Its just the remote start manual correct, cuz the 560xv is the remote start and alarm model.

Why would voltage gauge move when turn signal is on in a 1997 Chevy blazer?
The voltage gauge on the Blazer is not the most accurate (cheap) When using the signals the voltage draw on the system is enough to make the gauge move slightly.
How do you replace the front turn signal bulb on a 1998 Buick Century?
1. Open hood and locate the light assembly (left or right). On bothsides of the assembly you have a white piece of plastic that slides up and the whole unit comes loose. Make note where the light assembly connects to the car before removing the assembly. 2. Unplug the wire harness so the entire unit can be removed. 3. On the back of the light assembly, remove the round rubber piece for the bulb you want to replace to expose the light socket. 4. Turn the socket counterclockwise (about 90 degrees turn) and pull the entire bulb socket out. 5. Remove the old bulb from the socket by grasping near the base and pulling. 6. Insert the new bulb (in the same direction as the old one). 7. Reinsert the socket into the assembly by aligning the tabs on the socket with the holes in assembly and turn clockwise (about 90 degrees) to relock the socket in place. Then replace the round rubber piece. 8. Reconnect the wire harness and reinstall the white pieces of plastic to hold the assembly in place. Good luck. Should take about 5 minutes to do this.
dont know about the emissions stuff but if your planning to swap engines the ECM will also have to be switched as the 267 ECM will not work on the 305
Why would the wipers only work intermittently on a 1995 Pontiac Transport SP Minivan?
The front wipers on your 1995 Pontiac TranSport minivan are intermittent because there is a manufacturing defect in how a couple of connections were made (soldered) to a control board that is located in the motor assembly. I had the same problems with a 1996 TranSport and the fix took only minutes once the motor assembly was removed. Basically, it involves resoldering a couple of connections. Other than a few hand tools required to get the assembly out from under the hood, only a soldering iron and some solder are required.
There is a really good web site with a complete set of photos describing the fix once the box is out.

The wipers on my Transport got worse and worse until they finally quit altogether. Some have suggested replacing the control board but a healthy dose of solder will cure the problem.
What does the speed control sensor do?
It is important to know how fast a vehicle is going for many reasons. Since speed effects handing and braking times, you can't make proper driving decisions if you do not know how fast you are going. Speed sensors measure how fast a vehicle is going.
What is an output voltage swing?
Output voltage swing is defined as the maximum positive or negative peak output voltage that can be obtained without wave form clipping, when quiescent DC output voltage is zero.
VOM is limited by the output impedance of the amplifier, the saturation voltage of the output transistors, and the power supply voltages. This is depicted in the figure above.
This emitter follower structure cannot drive the output voltage to either rail. Rail-to-rail output op amps use a common emitter (bipolar) or common source (CMOS) output stage. With these structures, the output voltage swing is only limited by the saturation voltage (bipolar) or the on resistance (CMOS) of the output transistors, and the load being driven.Maximum and minimum output voltage is usually a design issue when dynamic range is lost if the op amp cannot drive to the rails. This is the case in single supply systems where the op amp is used to drive the input of an ADC, which is configured for full scale input voltage between ground and the positive rail.
Because newer products are focused on single supply operation, datasheets use the terminology VOH and VOL to specify the maximum and minimum output voltage.
It is because your shifter has not engaged in its place properly ( in park, P), therefore the ignition does not sense that it is in place and it wont let it turn and be pulled out.
Where can you find a wiring diagram for a 1997 Chevy Lumina headlights with daytime running lights?
Try MOTORLIT.COM Some libraries or schools have subscriptions to a database called EBSCO Host which has an Auto Repair Reference Center, think chilton on line. In Montana, the state funds it and all public libraries offer it. Worth getting into, endless diagrams
When does the diode not allowed to flow the current?
A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit.
The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.
Why does your clock lights fuse blow when you turn your lights on?
Fuses That "Blow" Repeatedly
Without being able to "hands on" troubleshoot the circuit served by the repeatedly blowing fuse, none of us can identify the specific defect which is causing your problem.
Therefore, the following generic answer can be applied to any electrical circuit, whether in a vehicle, or in a building, whether direct current [DC], or alternating current [AC].
Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] and other components from short circuit conditions and/or overload conditions which cause an extremely large flow of electrical current [measured in Amperes], which causes overheating of the conductors that results in damage to the insulation and the conductors.
And in a worst case scenario, the probability of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.
When a fuse or Circuit Breaker [and replacement fuses, or repeatedly "tripping" Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
The fuse or circuit breaker is doing what it was designed, intended, and installed to do; that is to protect the conductors and components of the circuit which it serves.
The proper "fix" for this issue is for a qualified technician, who knows what he or she is doing, to troubleshoot the involved circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse or before resetting a circuit breaker].
Some ignorant few people will suggest installing a larger fuse or breaker to solve the problem, BUT that will only increase the hazard, not correct it.
Do not follow "bad" advice by installing a larger fuse in a misguided attempt to correct the problem. To install an oversized fuse would almost guarantee damage to the wiring and the probability of an electrical system fire.
Can a 350 watt amp power 2 10inch subs 250 watts rms each?
depending on your amps rms, i wouldnt suggest it.
Why a diode can be used as a frequency multiplier?
A single diode alone can not multiply frequency - it can only divide frequency.
Two diodes in full wave split mode, or 4 diodes in full wave bridge mode, will seem to multiply frequency, due to the fact that alternating polarities of the AC wave will be flipped and superimposed on the resulting DC. It should be noted, however, that this is not true multiplication, because the result is not sinusoidal.
It is possible to filter the output and make it look sinusoidal, but that filter design will be very complex.
*************************************************************
Yes, a diode can be used as a frequency multiplier.
A diode is a non-linear device, and any signal passed through a non-linear device or circuit will result in harmonics being generated. If the signal passing through the diode is not a sine wave then harmonics of all the other frequencies present at the input will also have harmonics generated. There will also be the sums and differences between all the reultant frequencies.
That is why a diode is used as a "detector" in an a.m. receiver. Another name for a detector is a mixer, the other name for which is a multiplier.
