Re: Alternator External Bridge Rectifier

After reading the first post again and their website and their claims, I have made the following observations, and discussed them with someone more technically proficient in this area. These are just my opinions

The Quicktifier circuitry simply connects a second bank of diodes directly in parallel with the existing internal set-up. Provided that the external diode bank has a lower resistance than the existing internal set-up, it should carry the majority of the load.


It states "...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."

Solid state diodes do not wear out or become more worn-out, like moving parts these items either work or fail. The suggestion of significant wasted power is again BS.

"The greater number of diodes offered by adding the Quicktifier opens up the pathway of AC to DC conversion." (It was always open without them)

"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" in fact adds extra unwanted conductors, connections and components, all providing additional opportunities for faults to occur and component pieces to fail.


As it should run at a lower temperature this is a likely scenario, but this is not mentioned in the sales pitch and needs to be proven. As always with this sort of product, the definitive facts are not provided. I would like to see hard, proven data and figures showing increased performance. Before and after measurements of power, temperature reduction, etc.

Having searched various sources, I have not found one person who has reviewed this product. Surely such a device should have testimonials. This has been around for quite some time, over 8 years.



There is absolutely no protection against a short-circuited internal diode which, remaining in parallel, could still impose alternating current on the DC output and cause the "Christmas Tree" effect. In fact, a second set of diodes is included, thus providing twice the opportunity for this fault and scenario.

There cannot be any improvement in maximum alternator output as output remains solely under the control of the voltage regulator. The sole benefit is in reducing the current passed by the OEM diode bank. The argument hangs on the OEM being defective, in both design and manufacture. Any such advantage will be confined to periods when the alternator is running at close to maximum

I believe this idea is pitched to appeal to the gullible audiophile market, more inclined towards spending money on any extras that they can brag about. The key to the product is the I did-it-myself ingredient and the look-at-me factor.

As I said, any OEM or rebuilt guarantees will most certainly be compromised due to modifications and the possibility of faulty connections and the opportunity for external short circuits.
