I found your company first on eBay then I bought parts directly from your site. I probably wouldn't have a running car if not for Prime Choice! I couldn't afford everything to fix the suspension from any other place but your prices are so amazing. Thank you,

Rielle Wright

I just wanted to compliment your company on great service, communication, shipping and products. The purchase I made just recently arrived lightning quick. I was surprised because I placed the order almost too late to give you a chance to get it here when I needed it. But the order made it. I also worked with a couple of your folks on an ordering problem and they were very helpful. I will definitely try to call on you again for future orders. Thanks a lot,

Hi. Thank you for your refund, your professionalism and fast response. I am very satisfied. I plan on purchasing new wipers for both my vehicles and will plan on getting them from you. Also if your product is as good as they look I will inform my associates I work with - 250+ of your product. Thank you again and I look forward to dealing with you in the near future. Sincerely,

Paul Horniak

I ordered two sensors for my car. You sent me a confirmation and let me know that it had shipped. I PAID NO SHIPPING. You are the best. I am 59 and I appreciate the way you do business. To be a good customer should I tell everyone about you or just spend lots of money? Danny C. Graybeal

Half the price of anyone else. Very good quality parts and the how-to videos really helped. It took me about an hour to replace both front struts. Thanks and Regards,

Strut Assembly and Brakes. Well you are right - half the price, good quality and excellent service. You were so inexpensive I was suspicious. Everyone told me don't do it - go local. Well they are the loser and I am so thrilled. The job went well and I saved over 500 dollars. Thanks!! I am spreading the word. A Grandmother with guts,

Thanks for the great service! The parts arrived as promised and fit like a glove (also as promised). The instructions that were included made it relatively easy for me to do the work myself. That saved me over $300 on labor. Unfortunately my regular mechanic believes only KYB makes shocks and struts! I would recommend you to anyone and have! Thanks, again! It's been a pleasure doing business with you!

I am glad I found you on the internet. Your parts are so cheap (only in price).Thanks for the good service, fast delivery and free shipping. When I need any parts I will order from you and also tell others about you. (Family members etc.) Thanks,

How do Alternators work?

An alternator is the power base of your vehicle – it provides the electrical energy required to run essential components like fans (engine cooling, air conditioning), ignition coils, and nonessential components like car stereos, interior lights and cigarette lighters. Most people believe that power comes from the battery, and to some extent that is true. However, the power that runs all of those electrical components actually comes from the fuel used to run the vehicle. Essentially, the electrical power is generated by your crankshaft. It turns your fan belt which then rotates the alternator. The primary function of the alternator is to convert the power from the gasoline engine that drives you along the road to electrical energy. This keeps your battery fully charged and provides the electricity required to power all your electrical needs.

How can you tell when your Alternator is no longer working?

Initially you may not notice anything because the battery will continue to provide enough electricity to continue running the engine and the above-mentioned electrical components for period of time. A bad alternator is not going to immediately leave you on the side of the road. Still, if you were driving and knew your alternator was failing, it would be important to conserve power by turning off the stereo, blowers, and headlights (if you could do so safely). The battery reserve power might allow you to get home or to a local garage.

One major problem that will occur when your alternator is failing will be the lack of voltage to keep the engine running properly. This happens as the battery loses the last of its reserve power.

How can you tell if the alternator is failing without taking it apart and doing some measuring inside the alternator?

It's really pretty simple. You will need a simple voltmeter. You can get one at an electronics store for less than ten dollars. To tell whether or not your alternator is failing, follow these next steps. Start the car, make sure all the accessories are off and rev up the motor to a fast idle. Set the voltmeter to the DC scale (not AC or Ohms). Measure the voltage across the battery terminals – red lead of the voltmeter on the positive terminal, black on the negative (ground in most cars). The voltage should read around 14 volts. If it reads less than 12 volts, you may indeed have a failed alternator and may need a new alternator, you can skip the next step. Next, turn on the heater, the rear window defroster, stereo, headlights and anything else that draws power. Now rev up the motor and watch the voltmeter. It should still be reading around 14 volts. If it reads lower than 13 volts, your alternator is likely not in the best condition and you may want to consider a replacement alternator.

The last indication of alternator failure can be found in the noise it makes. The rotor inside the alternator rotates on bearings; these can be high precision bearings, and they can fail. If they do, you will hear a loud grinding noise coming from the alternator. To isolate the noise, get a length of tubing; any garden hose will do fine. Put one end to your ear, and move the other around in the vicinity of the alternator. The noise will be much louder when you point it at the alternator if that is the culprit. Other possibilities are the water pump and the power steering pump which are also driven by the engine belt. To further isolate the noise, disconnect the drive belt and spin the alternator by hand. If you hear a rumble or grinding noise, then the bearings are broken. If you don't hear a noise, the problem may still be in the alternator since the bearing might be quiet without the loading of the drive belt tension. Check for side play.
