Custom coils are designed to your exact specifications. They can be made either constant rate or varible rate.

Besides supporting the weight of a vehicle, the leaf springs control the ride height and keep the tires in contact with the road. Springs also affect alignment angles and are the most important components in controling the "feel" of a vehicles suspension system.

Constant rate springs defelct the same amount each inch. An example would be: 200 lbs. = 1 inch deflection, 400 lbs. = 2 inch deflection, 600 lbs. = 3 inch deflection, and so on. Constant rate coils have will restore your vehicle to its original height and ride.

Variblee rate springs defelct at different amounts per inch. An example would be: 200 lbs. = 1 inch deflection, 600 lbs. = 2 inch deflection, 1000 lbs. = 3 inch deflection, and so on. Varible coils have a soft initial spring rate and a much firmer spring rate to handle more weight, decrease sway, and improve handling.

Worn or sagging springs - Weak springs lower the chassis height of a vehicle, resulting in premature tire wear and poor handling characteristics. Sagging when loaded - Vehicles used for family transportation, works trucks, or sales fleets can benefit from upgrading to Broken original springs - Although uncommon in general, certain vehicles have been known to have a very high faliure rate of broken springs.

There is no standard life expectancy of springs. In general, coil springs on heavier full-sized vehicles tend to last longer than those on smaller light weight applications. To determine when coil springs need to be replaced have the springs inspected and the vehicle ride height checked by a trained professional.

The most common method of coil spring inspection is checking the vehicle ride height. Measure! Don't rely on eyesight alone! This method will only catch the extreme cases of spring sag or leaning. In addition to checking ride height, look for these signs, which also indicate the coil spring requires attention: Vehicle that commonly carry extra weight, resulting in unlevel condition most of the time (family transportation, work trucks, and sales fleets).

The UV lamp should be installed above the air conditioning coil. Drilling inside the coil frame is risky due to refrigerant lines in the vicinity.

When replacing your air conditioner or heat pump the answer is most likely yes. The efficiency ratings that are advertised for an air conditioner or heat pump are based on the performance as part of a matched system. If only the outdoor portion is changed, the efficiency and savings could be less than that of a matched system.

A T-coil is a device in some hearing aids that allows a hearing aid to pick up low-level magnetic signals from a phone. When a T-coil is used, the microphone on the hearing aid is turned off and the sound from the phone is delivered to the hearing aid via the magnetic signals. Because the microphone is turned off, T-coils help eliminate backgrounds noises and help the user hear only the phone conversation.

Electronic ignition has been around a long time; it was invented by Chrysler and used on their cars starting in 1971 or 1972, but didn't hit some automakers until years later (Volkswagen in 1980 - when they already had multiple-point electronic fuel injection!). The system is a computer-controlled way to deliver power to spark plugs without cumbersome and maintenance-heavy breaker points, and with better timing and far higher levels of current.

Coil bind takes place whenever a spring is compressed and one or more of the spring's active coils contact another coil. The rate of the spring increases whenever a coil binds since the bound coil or coils are no longer active (this changes one of the three rate-determining factors). Handling is affected whenever a spring coil binds. If the spring is compressed to solid height (all coils touching) during suspension movement, the suspension will cease to work.

One coil has a yellow wire and one has a blue wire (comming from the points). What cyl. fires off which coil.

Often, when hearing aid users place a telephone receiver to their ear, their hearing aid makes an unpleasant whistling noise. A telecoil option, added to a hearing aid, uses the electromagnetic energy produced by the telephone and eliminates the annoying feedback. The hearing aid will have a switch allowing the user to choose between the standard microphone mode and telephone compatible mode. Ask your audiologist to explain the features of your hearing aid to you.

In the above Q & A we talked about two and four conductor wiring in humbucking guitar pickups. If you have four conductor wiring, you can take advantage of the three wiring options in your question... coil tapping, out of phase, and series / parallel switching. By using a switch (like a push-pull pot) to ground the two colored wires that you soldered together from one side of the pickup, you'll get coil tapping.

Yes we can! You will need to email your logo for a price. All logos or custom tooling must be in jpg or tiff format and must be photo ready. For best quality engraving all lines must be crisp with no colors or shading. Price will vary according to the complexity of the work. If you know which product interests you please let us know.

The design of EMG active pickups doesn't allow access to the individual coil outputs from the pickups. As such, it's not possible to wire coil taps or pickup phase switches in the traditional manner. We do provide a number of alternative accesories to help you simulate some of these tone mods.
