Strobe will not fire

1. Turn on strobe.
2. Check the DS51 ready light. Turn the strobe's mode switch to
OFF and then back to TTL. Make sure that the switch has actually
clicked into position.
3. Check that the batteries are inserted according to the "+" and "-"
markings. It is possible to buy bad "new" batteries, so check the
voltage output with a meter if possible. If using NiCad or NiMH
batteries, make sure the charger is operating properly and that the
batteries are fully charged.
4. Check the mode switches and cord connections on the camera
and strobe. Check that the fiber optic cord or sync cord properly is
attached.
