About headlight switches:

In most cases, the headlight switch will control several other functions. Depending on your car, the headlight switch could control the headlights, high beam lights, low beam lights, park lights, indicators / turn signals and fog lights.

Mechanism of automatic headlight control (application of illuminance sensors) The automatic headlight control function detects brightness outside the vehicle with an illuminance sensor installed near the dashboard, in order to control when the lights turn on and off.
Bad Relays

If a bad headlight relay is a reason your headlights won`t turn off, the fix is to replace the relay. This is a little easier to check since there`s a chance that multiple circuits may use the exact same type of relay.

Always disconnect the battery when changing a blown headlight bulb. Headlight bulbs are connected to your vehicle`s electrical system. They`ll pull power from the battery while the alternator recharges the battery.
Electronic technology has advanced so that an electronic control unit (ECU) is required to control the functions of full LED automotive headlights. An ECU consists of mainly LED drivers for headlight functions such as high beams, low beams, daytime running lights, position lights, turn indicators and fog lights.
All the electrical systems in your car, including the headlights, are protected with fuses. These are designed to `blow` and break the circuit if too much power comes through them. This protects all the components on the circuit. If a headlight fuse blows, it could cause the headlights to stop working.
Car headlights are powered by the car`s battery when the vehicle is off. After you start the car, the engine begins providing power for all of the car`s electrical systems, including charging the battery. The alternator carries energy from the engine to the electrical components of the vehicle.
Today`s automatic headlamps come on whenever the switch is in the “auto” position and it`s dark enough to require them. They use a photoelectric sensor that`s usually mounted on top of the dash, or on the windshield near the rearview mirror.
The headlights of the automobile are wired in parallel. When one headlight of the vehicle is busted or destroyed, the other headlight still works.
The only tools you need for replacing the headlight bulb on your vehicle are a flathead screwdriver and the replacement bulb for your car`s make and model. However, to help protect your hands and ensure you don`t get fingerprints on the headlight bulb or other lens parts, you might also want a pair of work gloves.
Leaving Your Headlights on

One of the fastest ways to cause a battery drain is to leave your headlights on for long. If your car battery keeps draining, there`s a chance that you have formed the habit of leaving your lights on even when parked. Most times, your headlights stay on until the battery dies down completely.

Sometimes, the sensors do not react quickly enough when daylight is detected, either because the windscreen is dirty – hence limiting the amount of light passing through to the sensor – or the sensors are not sensitive enough. Solving the first problem is easy – just wash your windscreen.
Every gasoline-powered or hybrid car today contains a rechargeable 12-volt battery. This battery powers everything electrical: the engine`s control computer, the ignition system, the radio, the headlights, etc. So, the battery is vital to the car`s operation.
When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.” When you are replacing your car battery, It isn`t always easy to remember the order in which to disconnect and reconnect the terminals.
Your headlights rely on power from the battery to function properly.
If a switch is damaged, or you just want to update your fittings, it`s quite simple to replace it. Just make sure you write down exactly how the old switch was wired before you disconnect it, and wire the new switch in the same way. Also, try and keep hold of your original screws.
While you`ll need an electrician for most electrical work around the house, including diagnosing electrical problems and most installations, you can change a light switch yourself—but only if you have some electrical knowledge and understand proper safety procedures.
Instructions. It`s not uncommon for a vehicle to have panels or parts that need to be removed in order to change headlight assemblies. These procedures are usually simple, but a little time-consuming. If you`re not completely comfortable doing the job yourself, we`d be happy to recommend a professional technician.
Changing headlight bulbs in pairs assures that the road ahead will be properly illuminated and that drivers will get the full safety benefit of the vehicle`s headlights, just as the carmaker intended. Replacing parts in pairs can ensure vehicles are properly balanced and functioning safely.
The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse. Consult your owner`s manual to locate the main fuse for the headlight circuit and replace that fuse with one having the same amp rating.
Causes of a defective engine control unit

One of the main causes is a short circuit in the wiring or in components, which can cause them to burn out. This short circuit is often caused by external influences, such as the wrong start of the car.

The ECU has the important job of processing all of the data that is sent by the sensors throughout the vehicle. It “uses” the sensor data that is being sent to help read the messages revealed by the vehicle on its current status.
Mechanism of automatic headlight control (application of illuminance sensors) The automatic headlight control function detects brightness outside the vehicle with an illuminance sensor installed near the dashboard, in order to control when the lights turn on and off.
Automatic headlights tend to work by using photoelectric sensors embedded into the instrument panel, around the base of the windshield. These sensors tend to rely on ambient light level rather than on visibility perceived by the driver.

Intermatic Tl11-70 24-Hour Mechanical Time Switch

This was used with the manual on/off switch to control the pool filter. Today I decided to set up the timer so I pulled out the dialas directed. The trippers weren’t there so I just put the dial back in. Now the manual switch won’t turn on. Help please! and thank you.

ANSWER : With the Intermatic timers I’m familiar with, pulling out the dial but, if it pulled out and turns to lock, make sure you have it back the way it was. Obviously the time is doesn’t matter because you are using it manually. Anyway, the dial shouldn’t really effect the manual switch. If you disconnected any wires or if any came off , you will need to put them back. The system is pretty simple, just like a house switch. It sounds to me like the breaker is tripped or a wire came off.

Razor E-100 – The toggle switch was broken, I replaced it with another lighted switch, but the switch won’t light. The motor runs o.k., why won’t the switch light when turned on? Thanks.
ANSWER : The Switch can be almost any but the lighted switch has to be a compatible 24vdc lighted switch.
As seen on this web page.

Need the wire diagram to rewire my Ariens lawnmover to bypass the safety switch. It is Ariens GT-19 model # 931026 Serial # 001463.
Can you help? It is an old Ariens mower but still runs good but now I need to bypass the safety switch in order to run it any longer. The local Ariens dealer said I need to go through the internet and get the wire diagram as they cannot give it to me directly. They told me I needed the wire diagram and the part involved in bypassing the safety switch. Hope this is all the information you need to help me.

Thank you. Roger Fielitz

ANSWER : Here is owner manual: the switch is behind the ignition, sometimes at the N position of gearshift, just look for a switch with one wire coming in & one going out (usually the same color); disconnect the two wires & jumper them together to bypass the switch. Looks like yours has one under the seat.

Hayward motor needs replacement toggle switch, and the motor has AO Smith on it…can i just replace it with a simple 3way toggle switch or do i have to purchase a pricy pool toggle switch?
ANSWER : You should be able to use just about any toggle switch; however, you need to ensure it is rated for the proper amperage. In other words, if your motor is rated for 10 FLA (Full Load Amps), you are going to want a switch capable of handling at least 15 FLA.

Switch for 1990 evinrude not marked old switch has 6 terminals all
around switch new one has 5 around but 6 one is in the center. I do
not know what goes to what.
ANSWER : HI.Were the switch going to the terminal of the battery?

My swimming pool. I have just had my fifth IC 40 Intellichlor chlorine generator installed in 4 years at a cost of over $900 today. Each one has worked for no more than 8 months. The first three were replaces under three year warranty, the fourth by a factory rep and I bought the fifth today. The first three all failed with Flow Chk PCB error message. The fourth just stopped working on Sunday, no power or lights. A local Pentair warranty person, whom I paid a Service Call, unplugged the unit, opened the small power center cover, showed me the green light indicating that there was power, plugged in a new IC 40 which worked immediately (as did the other four). I asked if I should replace the power center and he said that it’s basically just a transformer and is working fine. We do get occasional power blips that make the clocks on microwaves, etc blink, but I thought that the power center essentially isolates the cell from these. I do have a Florida Power and Light surge protector on the electrical box that brings power into the house. I have now talked to the pool builder, two Pentair warranty repairmen and one factory rep. I am at a loss. They all tell me they have no idea why these units fail after less than a year. This last IC 40 was installed 3/24/2010, version 2.0 and now failed in less than 5 months. Should I replace the power center that the IC 40 plugs into. Any other suggestions. I have been told that this is the best chlorinator. I don’t want to keep replacing units. By the way, each unit had been spotless inside. I keep the water chemicals and salt levels at ideal levels. The units have never worked long enough to get dirty inside. The power center is connected to an Intellitouch control system outside with an indoor control panel. Last time I called Pentair North Carolina and got some smart alec tech person that had no suggestions. Please Help if you can.
ANSWER : I’ve had the same experiance. On my fifth one as well. Fail every year. No idea why.
