HI thank you yes it is an ultra 1800 i mispoke. This constant flashing that seems to happen may be from a bad ground.
the flash that does not fire accept for the first time (then beeps at me) seems to be working better now would this be a bad ground as well? I use the cyber commander to trigger but i also test them with the button on the back.

Ok, first, there is no Ultra 1600. Ultras were 600, 900, and 1800. Ultra Zaps and X series were available as 1600's, as were Alien Bees. Not to be pedantic, but knowing the actual type of light can be important.
Secondly, make sure you are using a grounded AC outlet, and remove any extension cords or power strips. Change circuits our outlets if needed. If there is anything in the RJ11 jack, remove it and see if the problem persists.
With the units unplugged and left to sit for several minutes, remove and reseat the flash tubes to ensure they are making proper contact. While out, make sure the legs (outside the glass) are not charred. If they are charred, the tube has arced, and the flash unit will need to be repaired. Blackened areas inside the glass are normal and expected.
Also, how are you triggering the flashes?
