I have a problem that just occured. I swapped my Futaba RX pack from my boat to my plane, (just after using my boat) and now it wont work in my plane. I'm not sure how ot check the volatge, as all the methods I rtied show a ery minimal reading. Coud it have been discharged? Also, when i hook it up to the charger, the charge light wont come on. Coud there be a problem in the switch? Im not quite sure how the charging works so I can;t do much trouble shooting, and the make the problem wprse, the charger cable is broken at the end that plugs into the charger. I have experince fixing this but not sure what goes where, becuase the light only comes on when the two wires are touhing? ANy help is appreciated thanks.

A couple of questions:

Can you take it back out and charge it whichever way you did when it was in your boat?

Yes, it could be discharged. Remove it from your plane and hook it up to the meter and see what it reads.

What kind of charger do you have?
