No matter what I say or print on instructions, people just don't like to read.  There is nothing more I can do about it except if you do not understand something, call me.  My numbers are on the page "contact me" and most information on how to insert the module is under flash and cables. You can do damage "just fooling around".

Not as often, we will experience a flash failure. KAA-KAA, the ancient God of bad luck rears it's smiling and ugly head.  Understand please, most of the flashes we provide cables for are made by the manufacturer to suit his camera line. 

Though they may be marked PRO or HD or whatever, it does not imply these were designed for extreme hard use. They were designed to operate at slow speeds, no heat buildup, subsequent fast flash pictures at partial slow settings, not at high repetitive speeds, lots of cool downs and infrequent use.  Sometimes they need to be rebooted.  

You may try the following;  Reset the flash to it's default settings.  It's like rebooting a computer.  Get out the instruction book. You might try turning the flash off and restarting it with the mode and on button pressed at the same time. And some flashes have to be turned on after the camera to handshake. 

Loose cables can occur at any time and nine times out of ten it's when you about to take "The Shot Of The Year". Thats another reason why we eliminated the RCA jack they pulled out, locked on too tight and could not be removed, or a fan of the blades fell off and shorted the cable.  In our product we use locking DIN plugs, they are externally protected, all grounding is internal, where it should be. 

Use the Isopropyl Alcohol to clean the flash internal contacts and the shoe of the flash where it makes contact on the prism. If you do use AA cells moisten a piece of paper towel with ISOPROPYL and wipe the batteries top and bottom to remove finger prints and oil residue.

I get a pack back sometimes with erratic behavior. I have removed coca cola from the insides and water sometimes.  But slow operation can be from the cable from the battery to the module that goes in the flash.  That brown to red color is heat. Burning the heck out of your flash shooting at extreme settings is one thing. We all get behind the ball shooting and try to catch up usually at the expense of our own gear. 

High power and fast pops without cooling the flash is common to sport shooters, paparazzi, and nervous wedding shooters, I call it shellac syndrome.  

Most manufacturers strobes are not made for abnormal usage. Quantum and other board makers sometimes spray the internal parts of their boards and products to weatherproof and seal the metal stripes. 

The shellac is used to insulate and prevent moisture damage.  The shellac settles on the terminals making them brown.  It could also be the capacitor is getting so hot, you are about to experience a meltdown. Some are covered with paper as an insulator and then wrapped in shellac.

Ever try to solder with a dirty solder iron tip. It don't work, does it , thats why you clean the tips.  What can occur is "fast shorting" contacts that open and close rapidly. Thats what I think may of been the problem with the 580's when they first came out. Weak contacts internally.  

Several ways to clean, ISOPROPYL ALCOHOL, not rubbing alcohol.  A grade or percentage of 93 or better.  Also a soft eraser done away from your gear and lenses, and a vacuum cleaner running while you do it to prevent any abrasive from going internal especially on camera contacts. When I repaired cameras, I had a vacuum table to keep particulate in place. 

Isopropyl alcohol is readily available at the drug store. It is used widely as a solvent and as a cleaning fluid, especially for dissolving lipophilic contaminants such as oil. I use LKG 99.6 percent. I also use a dremel with small wire and eraser tips to polish terminals when really bad.


The modules can also be inserted wrong as in backward. Some of the modules are easily confused.  In that case you can short the strobe or simply most newer ones have protection and don't function. On this site there are sections on specific cables with specific instructions under flash units and cables.

Another possibility occurring with the cables is stretching. Many claim they don't stretch the cables.  

Well after taking things with a few grains of salt, two shots of Tequila, and some lime juice I see things differently. 

This shot taken at a local Lambada Dance contest got the photographer who was so into the music he just grabbed this incredibly gorgeous young lady and almost won first prize taking his own portrait at the same time.

I do have some great guys and gals using the black box. And we'll put up any decent shot you send us using black boxes providing I don't get any letters from the Religionistos. And even then I'll put them up.

Under careful scrutiny I did notice he is still using the older RCA jack which we have upgraded free for years during the time of sale of the Black Box.  By simply sending them to me with fifteen dollars enclosed, we will upgrade the cable to DIN, clean the terminals and ports and send it back to you. Thats another weak link we have over the year attended to. 

3)  We have experienced a few failures with the DIN plug by the retainer screws working loose. from time to time tighten them - Remove one screw at a time, put clear nail polish on the threads and re-insert. From 2009-2011, I now torque them down, we use a different series of shrink tubing,  and Blue Lock-tite the two screws. Send you cable in and we'll upgrade it for free, just enclose $5.00 for return high speed priority mail service.

The last thing about cables is old age. Sometimes we rebuild an older Quantum Cable no longer being used.  We can do that for the Vivitar or make you a great extension for a two cable rig. Only if I deem the cable is OK, will I update it. Cables can corrode internally and the copper has turned green or the rubber has disintergrated and literally falls off. Unseen breaks and we run contiuity checks. Anything other than 000 perfect and we dump them.
