Interfit EX150 Mark II Two Flash head not firing

If you had the ATG Gold MG8k Flash Kim X3, then your 430EX II or 580EX II can transforms into wireless radio ATG ETTL II.

If you are using the outdated wireless IR ETTL with a 580EX II as a Master. Then you have to set the Slave (ATG/580EX II/430EX II) body facing close to the Master.

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.

More info needed: Will the flash fire when you push the test button? Have you rest the camera you're using to factory defaults while the flash is mounted on the camera and turned on?

It could be the bad bulb. You need to replace the entire bulb assembly. Canon Speedlite 580EX II MYK Camera Camcorder Repair

sometimes there is no manual included in a new ex150 but there is a CD or DVD with some instructions .. not much in the way of how to make things work but safe use and assembly and simple setup .. here is a bit of information that might help:

Canon MP170, MP450, MP530, MP600, MP610, MP800, MP810, MP820, MP830, MP960, MP970
MX700, MX7600, MX850

1. Switch off the printer the button Power

2. Holding button Resume (the red triangle in ring), include the printer (press the button Power ) - an indicator fires green cvetom.

3. Holding button Power , release the button Resume

4. Not releasing button Power , two times press the button Resume and release both button.

5. After indicator of the cut-in/readiness flashing.. and fires constantly, fall into service mode.

6. Four times press the button Resume , under each striking Resume indicators are switched: green-yellow.

7. Once press the button Power for acknowledgement of the selected action (the unset of the counter абсорбера). For switching off the printer button Power press once again.

Good luck!

You have a defective PC Cable.

Try this:

Turn on flash and wait until ready.
With PC cable connected to flash only.
Short out center pin to outside of PC Cable, this should fire the flash.

How old is that Flash?
In my opinion, battery is dry and flash circuit is OK.

Hmm...I can't find a software control either. When the flash is down there is a cross through the lightening mark in the upper left portion of the screen, and when I press the flash button and raise the flash the same lightening mark in the upper left has no cross through it. Do you have the same mark? Does the flash button have no effect upon the mark?

Hi Guys!
I have had the same problem on CT-1 s and CT-5s.
In both cases the flash cable (called PC synch cable) was to blame. If flash fires correctly with the test button on the handle, then cleaning the cable contacts with contact cleaner spray seems to be the best first step.
