Have a Sure Fire 99913 flash light stopped working New batteries no help

The flashing red light indicates that the camera's flash is charging.
Your electronic flash does not work on the low voltage supplied by the camera's battery. Instead, the battery is used to charge a capacitor(s) that are connected in a manner that raises the voltage to a level that will fire the flash. If the batteries are not adequately charged or the capacitor(s) are leaking, which will occur as they age, enough voltage will not be stored to allow the flash to fire.
Make sure your batteries are fully charged. Remember, rechargeable batteries do go bad after time and must periodically be replaced.
If the battery is fully charged and the red light continues to flash, the camera will need to be sent in for repair (probably replacement of the capacitor(s)). Call the Nikon Service Center at 1-800-645-6687 9AM-8PM EST, Monday to Friday, and they can arrange for you to have your camera evaluated and provide you with an estimate without cost. Your camera is rather old and it is possible that it might make more sense to replace it with a new model.

Caroline, you should try to set the camera on "M" and the flash in 2nd curtain flash sync.

Or set flash in ATG wireless IR ETTL Slave modes and pop-up the flash on Canon EOS-70D.

Make sure you using flash grade batteries and not rechargables. try energiser ultra or litiums or duracelll plus but nothing else. if the charge light is not coming up then most likely batteries. I would take it to your local camera shot and test your 7d with one of thier 430 just to make sure the hotshoe didnt short out the flashgun

Does it fire when you push the test button (red light)? If so make sure the contacts on the lens and on your camera are clean. My speedlites sometimes don't fire after heavy use and I clean the contacts with a soft cloth and some methylated spirits or isopropyl alcohol. Hope this works for you.

flash bulb could be burnt out...if it doesn't fire when when you push test, that's my guess as to the problem. Another possibility (although unlikely) is a loose connection in the flash.

Hey i have a 430ex mk1 which when turned on did not fire and red pilot light did not show , i have had the flash since 2006,

i have also tired new batterys and the LCD Light works and the Txt shows up,

Send that back to Nikon for service. http://www.nikonusa.com/Service-And-Support/Service-And-Repair.page

Hello,

Check dirty contacts.

Do this test:
Fresh 4 batteries
Turn on and wait until flashing Green Light.
With insulated wire, both ends stripped to 1/4" of bare wire, short one end to Center of flash shoe and the other to metal outside contact.
Make sure flash is not facing at eyes.
Shorting it should fire the flash.
Or connect the PC Cord to flash and short Center Pin to outside.

I have the same problem, I have looked every where even on the Olympus site and have no luck finding anything, I paid £280 pounds for this unit and have hardly used it. Took it to a few repair center's & they reckon £200 pounds to repair it (how can that be) I only want it repaired and am sure it is the bulb I don't want to buy a new one this could happen again at great cost to me. I have to say I am not very happy with Olympus at all, bad service, & lack of help with this problem.

If your using the hot shoe with an external flash, three things could've happened: battery power in your camera is too low to fire the flash; or check the menu/settings/flash - ext flash settings may not have been chosen by the camera, but you may need to set it first manually; or your hot shoe is not a hot one, but your flash needs to be plugged into a PC outlet on the side of your camera. One last thing - test fire your flash and make sure it works to rule out the camera. There have been occasions where the ready light works on the flash, but it won't fire even after being plugged in. This problem was found to be a loose soldered wire in the flash foot. Another time it wound up to be the flashtube. Hope this helps.
