During my last couple shoots I've been running into some problems with my AB800s. I will plug them into my vagabond and sometimes one or two the lights won't go off. I figured it might be a problem with the power source, but the problem is still apparent when I use a wall plug. I then figured maybe I had to change the batteries in my PWs, and even after that nothing. I even tried using the dedicated sync cable from AB and I still couldn't fire them. If I push the test button on the back of the lights they go off without a hitch. Sometimes when I remove the softbox from the lights they will start firing, but still not all the time. Any ideas or suggestions, i feel like I have tried pretty much anything I can think of. I've had the lights for just over 3 years if that is any consolation. Is it time for a change?

Any suggestions greatly appreciated.
Casp.

Will they fire when triggered by the optical slave?

Depending on the mood of the lights....maybe 20% of the time.

its just odd that both lights are experiencing this problem at the same time.

silly question, but are you sure you are letting them recharge enough before firing again?

There are times when I wait up to a minute between shots just to make sure I give it enough time to recycle, and still run into the problems mentioned above.

:lol:


is this problem at all power settings?


Don't try to confuse me with the facts, my mind is already made up.

Hmmmm good question, in all honesty, they have gone down to around 1/2 power and the problem still remains. Have not tried with a lower power setting.

You'd probably get a better answer on PCB's forum than here, but something else to consider. The older AB's have seperate power supplies for the cap charging vs. the trigger and other stuff. If I remember correctly once you drop below 60 volts or whatever it is, the electronics NOT related to the flash tube charging can act up.

My initial experience with this was based on a home-brew 12v system that couldn't meet the load and would "brown out" for lack of a better term the AB's. My experience was different however, since the strobe would go into a repetative machine gun style mode and I had to power it down to stop. If you are using one of the older Vagabonds and NOT the new mini, then it may be worthwhile to check out the SLA battery and make sure its good.

OF course none of this accounts for the house power and issues with that.

Are you using a power strip or protector in both the wall or battery configurations?

Interesting points. I suppose the part that concerns me is that this problem persists even when plugged in to a wall outlet. I do have the old vagabond, and once I straighten out this light situation I will purchase a couple on the new mini ones. As for my configuration, it's basically an extension cable that at the end has three heads to plug the lights in to. I was told that a power strip would drain the vagabond battery pack even quicker,

What rating is the extension cord and how long is it? The ABs initially ask for a bunch of AMPs on recycle then taper off during the charge. Put two of them on an under spec cord and that's why u have a problem on main or batt. Do you have any issues with a shorter ext cord OR directly connecting the two ABs to different supplies?

On a side note, that SLA battery is probably due for replacement if it hasn't been within the last 2 yrs or so!

Again, some very interesting points that I am going to have to explore adn get back to you with the results. The SLA battery has not been replaced since ownership. The extension cable is 25 feet, and off the top of my head I have no idea what the rating is (is there a way to determine that?). I guess the only thing that concerns me about about your points is that I have used this exact setup for the past three years or so and these are my first times encountering these types of problems.

Just call AB and arrange for them to have a look at them. Their customer service is outstanding so I wouldn't hesitate to trust their opinion. If you had sent them in when you first encountered the problem... you would most likely have them back by now.
