Introducing the Quicktifier 210 and the Quicktifier 420 Heavy Duty Dual/External Bridge Rectifier System

Our unique secondary bridge rectifier system can recover wasted power (power you paid to generate but loose) from your alternator. Plus, it takes the load off the alternators internal rectifier giving you greater reliability and performance.

How the Quicktifier Can Make Your Stereo or Two Way Radio Sound Better

First, let's mention how the "Noise" in your stereo is generated. Some "noise" comes from ignition components, but considerable noise is generated in the vehicle's alternator. When the alternator generates power it does so in the form of AC (alternating current). Then the diodes in the bridge rectifier convert the AC current to DC (direct Current) to match the vehicles electrical system. The "Noise" is generated at the point where the AC current "Squeezes" through the diodes to be converted to DC current. The lower amperage or more worn out the diodes are in the alternator the more noise they will make in the electrical lines which comes out your speakers.

The greater number of diodes offered by adding the Quicktifier opens up the pathway of AC to DC conversion. The average alternator has 6 diodes in the alternator. The Quicktifier 420 has 12 diodes so if you add that to an alternator that already has 6 diodes you end with a total of 18 diodes. You can imagine current will pass through 18 diodes much easier than it can 6 diodes. The easier pathway increases power conversion and reduces noise in your speakers. This product makes sense and works, let it work for you.

How The Quicktifier 210 and Quicktifier 420 Heavy Duty Dual/External Bridge Rectifier Systems Work

Alternators make AC (alternating) current using a bridge rectifier with diodes to convert that AC current into DC (direct) current for use by the vehicle's electrical system. When your alternator's voltage regulator senses the need for electricity the regulator tells the alternator to start making electrical power. The alternator is then turned on and making electricity it taking power from the engine to generate the electrical power in the alternator, the more electrical power an alternator makes the more it costs.

Here's where and how you loose some electrical power from your alternator. When your alternator is making AC power, which you pay for, and your bridge rectifier cannot transfer that AC power to DC it gets rid of it in the form of heat. You pay for generating power, then some of it gets wasted in the form of heat, because the alternator's internal rectifier is not efficient enough to transfer all the AC power, which you paid for, into DC power. To top it off, the more demand you put on your alternator the internal bridge rectifier becomes less efficient and more power is wasted.

So if you are powering an alternative energy system or some other continuous demand system you are paying even more. The Quicktifier 210 and Quicktifier 420 help recover that wasted power by tapping into the alternator stator leads where the AC power is generated. By taping into these AC lines before they go into the alternators internal bridge rectifier the external rectifier is offering a more efficient pathway out of the alternator in transferring the AC power generated into DC power. The increased throughput of higher amperage rated diodes, larger wires and a high volume fan to keep the external rectifier cool work together to create greater efficiency and less wasted power.

The Quicktifier 210's rectifier is rated at 210 amperes, the Quicktifier 420's is rated at 420 amperes, much higher than any alternators internal bridge rectifier. Because of the recovery of formerly wasted power you can power your system, whether it's your stereo, alternative energy System, Emergency vehicle, or other high demand system for less money and less down time. The Quicktifier-210 or 420 will make electrical systems work better and your alternator's bridge rectifier last longer.

The Quicktifier 210 or Quicktifier 420 can be connected to just about any alternator by an experienced alternator technician. Our Unique external rectifier system helps recover wasted power from your alternator plus adds greater durability against bridge rectifier failure caused by heavy use.

General Instruction on How to Install the Quicktifier

These are general instructions and may not include all details for installation on your model alternator. For more information see the installation videos or talk to your local auto electric service tech. Use extreme caution and care when installing this product. You are working with alternating current (AC), the same that is in the electrical outlet of your home. Alternating current can kill. Make sure that the three AC lines that run from the alternators internal bridge rectifier to the quicktifier are secured well and covered with wire conduit to further protect. These wires should never be allowed to touch & rub on any metal surface. If they short to the metal part of the vehicle it will send AC current through the vehicles metal components, potentially causing great damage & possible death.

Basic Installation Instructions For GM Alternators

quicktifier layout
Figure 1

Step 1

First, you determine if your alternator is the type that needs to be opened up to connect the Quicktifier system or does your alternator have a cover on the back that can easily be removed and the system installed.

If you have the alternator type that needs to be opened up this is what you do. Open your alternator by first removing the case screws, then pry the two halves apart. If you have the alternator type with a rear cover that needs to come off you remove the cover. On the alternator type that you split apart you must make sure you reset the brush holder by pushing the springs & brushes back into the brush holder case, then use a pin or a toothpick in the hole that comes out the back of the case. remove the pin after your put the cases back together.(on units with rear cover you don't do this part) Once the alternator is apart you locate the three (AC) stator leads attached to your alternator's internal bridge rectifier.

Some alternators have nuts & studs, some have screws and some stator leads are soldered to the bridge rectifier. For both the nut & stud and screw type you use the ring terminals provided to attach the stator leads. shrink tubing, insulate the already terminated ends of the AC wire, and attach those to the bridge rectifier leads.

Now, route the leads outside of the alternator case, this is easily done by using an existing hole or drilling a small hole in the rear case then installing an insulating grommet or bushing the make sure the wires do no short to the case and are secured well inside the alternator so the do not hit the spinning rotor inside the alternator.

Step 2

Once the cables have been attached and safely routed, put the remaining insulators on the AC wire and crimp the three included ring terminals to their stripped ends. Connect these terminals to the bridge rectifier, or bridge rectifier stack, inside the quicktifier. It does not matter in what order the AC wires that come from the alternator connect to the 3 studs in the quicktifier.

Step 3

Now that the Quicktifier is attached to your alternator, close the quicktifier case and mount both under your hood. Connect a ground cable from Quicktifier negative (-) to the battery negative (-), and connect a fused positive battery cable from Quicktifier positive (+) to battery positive (+). Then run a ground cable from the alternator case to the Quicktifier negative (-) and a positive cable from alternator battery post to quicktifier positive (+).

Step 4

With the Quicktifier nearly hooked up, now run a line with a 1/2 amp fuse inline from a positive ignition source (a line that is only hot when the key is turned) to the red ignition cable on the back of the Quicktifier. A male spade crimp connector is provided for your convenience. Connecting this line runs the fan and is crucial for proper quicktifier installation and use.

Basic Installation Instructions For the Ford 3G, 4G and 6G Series Alternators

The Ford Motorcraft 3G, 4G and 6G series alternators have 6 stator leads, the Quicktifier 210 and 420 only uses three of these stator leads, the other three leads are for the "Y" connection and are not used.

Step 1

On the 3G you remove the voltage regulator/brusholder assembly before taking the thru bolts out and prying the rear housing off the bearing. The 4G you do not have to take out the thru bolts, it has a cover on the back that you remove to expose the area on the bridge rectifier where the Quicktifier leads attach. The 6G series you remove the three through bolts then pry the rear housing off the rear bearing to expose the stator leads.

Step 2

On all 3 of these alternators you connect the Quicktifier 210 or Quicktifier 420 to stator leads #1 #2 & #5 with number 1 being closest to the main positive battery terminal on the rectifier.

Step 3

Once you attach the 3 wires that go to the Quicktifier you either drill holes in the rear cover or you run the wires through the air holes in the cover of rear housing.

Important: When running these AC lines from the alternator to the Quicktifier box you must make sure they cannot rub or short out on any metal part of your vehicle. Alternating current can kill. Never work on the Quicktifier with the vehicles engine running.

Basic Installation Instructions for Nippondenso (Denso) Alternators

Nippondenso (Denso) alternators are commonly used on the following makes: Toyota, Acura, Honda, Jeep, Dodge, Chrysler, Plymouth, Lexus, Mazda, Jaguar, Chevy, Geo, Suzuki, Daihatsu, Isuzu and Sterling.

stator leads

Step 1

Installation of the Quicktifier External Rectifier system on the Nippondenso (Denso) alternator is very easy. Like the GM AD series alternator only the rear cover needs to be removed to access the connection points required to install the Quicktifier, as shown on the left. The rest of the alternator does not need to be disassembled.

Step 2

The photo shown on the right shows the first lead to connect to the Quicktifier. Notice how the rectifier stator lead connector only uses a Phillips head screw, no soldering required! Simply crimp on the supplied ring terminals and insulate them with the provided heat shrink tubing. Then either split the ring terminal or remove the Phillips head screw to attach the Quicktifier wires to the internal bridge rectifier.

Step 3

This part is very important: The Quicktifier only needs three (3) of the four (4) leads shown on the stator. Choosing the correct three (3) leads is very important . The photo on the left shows that one of the terminals has three (3) leads to one connection , do not connect a Quicktifier wire to this lead. Connect the Quicktifier AC wires to the other three (3) terminals that have a single connection to the stator, not to the one (1) that has several stator connections to one terminal.

quicktifier wires attached

Step 4

Connect the rest of the Quicktifier wires to the proper stator leads on the bridge rectifier. The finished product should resemble the image to the lower right . Some models of the Nippondenso alternator have stators that are double wound , they will have two (2) stator connections for each terminal and six (6) on the unconnected terminal. Proper connection of all three (3) Quicktifier wires is required for operation.

Step 5

Once the Quicktifier wires are connected to the proper stator leads on the bridge rectifier, drill holes in the rear cover so the Quicktifier wires can pass through. NOTE: The holes must be large enought so the wires do not short out on the cover. This would cause the case to be excited by AC and could lead to severe burns, vehicle damage, or death.

Step 6

When connecting the three Quicktifier terminals connected to the alternator inside of the Quicktifier External Rectifier module, order does not matter. Simply cut the wires to the required length, strip the ends and crimp on the provided ring terminals and insulate with the included heat shrink tubing. Then remove the nuts from the Quicktifier bridge rectifier stator studs and slide on the ring terminals, replace and tighten the nuts using a small amount of thread locker. When the cover is replaced and the wires are connected, wrap them with the provided looming and secure the overall wiring so it cannot short out. Shorted AC lines are very dangerous. Connect all wiring as shown in Figure 1 wiring diagram above.
