TS Pit Crew,
Hope you guys can get me tuned up and back on the track. I'm having trouble powering up a used R-44 I just grabbed on the YS. I can plug the unit into the wall and it will turn on and works fine. My next step was throwing in some AA batteries into the unit so that they act as a backup when the external battery runs low, they kick over to the AA. The unit will not turn on with just the AA batteries. The unit will not turn on using the external battery.
I'm hoping to find a solution. If anyone can help out give a shout.
