John Timmis Posted May 22, 2021 Share Posted May 22, 2021 Hi. I connected the transmitter ( futaba 6EX 2.4) to the charger this morning. No green light on the charger. The charger is ok, it's working on another tx ( field force 6). The transmitter still works ok & shows 10.5v on the display. It is fitted with an eneloop battery. All suggestions welcome.

Gary Manuel Posted May 22, 2021 Share Posted May 22, 2021 Is the tranny switched OFF properly? I believe that they have a changeover switch to prevent charging while switched on. Quote Link to comment Share on other sites More sharing options...
FlyinBrian Posted May 22, 2021 Share Posted May 22, 2021 Some tx have a diode and or fuse in the tx charging circuit, I have known the fuse to blow so preventing the tx charging. Quote Link to comment Share on other sites More sharing options...
John Timmis Posted May 22, 2021 Author Share Posted May 22, 2021 Hi. Thank you both for your ideas. I have just returned intending to swap the battery to another tx to try. Thought, 'I'll just try it one more time'. Guess what? Now it works fine. Thanks anyway. Funny things these electrons. Cheers John Quote Link to comment Share on other sites More sharing options...

Low pass Pete Posted May 23, 2021 Share Posted May 23, 2021 Perhaps a look at the battery connections and charge point could be worthwhile. Quote Link to comment Share on other sites More sharing options...
J D 8 Posted May 23, 2021 Share Posted May 23, 2021 The charger that came with my T8j proved to be pretty rubbish, just could not trust it to do its job. Replaced with a charger from Weston UK. Quote Link to comment Share on other sites More sharing options...
FlyinBrian Posted May 24, 2021 Share Posted May 24, 2021 (edited) I think any charger that tells you how much you have put into the battery and allows you to check the battery capacity is far preferable to the usual wall warts supplied with the radio. I normally check the capacity of my Tx battery about once a month and of my rx batteries if I have not used the model for a while. In general use I have a fair idea what it takes to recharge my receiver battery and it is surprisingly little. On a days flying, say four flights I expect my 5 cell battery in a 5 servo .91FS powered aerobat to require about 400mAH to recharge. A charger that can run on 12V is also very useful as, just in case you forget to charge and want to go flying you can top up on the way to the field or at the field if necessary.
