11.6 is one bad cell, time for a new battery.
My LX-7 has a green light at 13.3 volts
I have never seen it blink, if I plug it in and it is not connected to the unit the light is green, if I plug it in and it is connected to the unit and the unit needs charging it is red
When you plug your charger into the outlet does it blink red for awhile or turn green?. I let the machine die today and trying to charge from dead. I plugged it in and the charger light blinks red, it usually stays constant red when plugged in but it has a faint red blink...
Phill Charge the battery with the charger from one of your other flashers while you're waiting for anew charger from Marcum. At least you'll know if the battery is ok then.
I did that today... the battery is fine.. it was the charger that crapped out..
