graham dallison Posted March 9, 2017 Share Posted March 9, 2017 Went to charge my TX, plug in the charger but the green light failed to flash. Voltage on display shows 6.5, checked battery voltage 6.5, checked output on charger 12.00 so any one any ideas. Quote Link to comment Share on other sites More sharing options...
Dwain Dibley. Posted March 9, 2017 Share Posted March 9, 2017 Could it be as simple as a blown led bulb, we get this a lot on our panels at work. Leave it on for an hour then check voltages, assuming you haven't already done so, and see if there is an increase. D.D. Quote Link to comment Share on other sites More sharing options...
Dwain Dibley. Posted March 9, 2017 Share Posted March 9, 2017 12 what by the way, out put from the wall charger should be 1 Amp or so, depending on make. I always use my lipo charger and charge nimhs at 400Mah. on the nimh setting of course !! D.D. Quote Link to comment Share on other sites More sharing options...
graham dallison Posted March 9, 2017 Author Share Posted March 9, 2017 Had it on charge over night with no increase in volts. The 12 was volts. Sorry for my ignorance but no way for checking Amps. Think I will go to lipo and remove for charging. Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted March 9, 2017 Share Posted March 9, 2017 A charger has to pump in whatever power has been used from a cell or cells And an unregulated supply can be measured way over the voltage printed on your pack Most chargers will show a higher voltage when no load is applied The voltage should be correct when connected to the pack One LED would not cause this discrepancy, but you could replace the LED Edited By Denis Watkins on 09/03/2017 20:07:14 Quote Link to comment Share on other sites More sharing options...
Peter Christy Posted March 9, 2017 Share Posted March 9, 2017 I think the "wall-wart" is just a power supply on the X9D. The charger is in the Tx. You haven't been plugging an external charger into the X9D, have you? That is a sure way to blow the internal charger. You should only use the supplied power supply to use the internal charger. However, most of us just unplug the NiMh pack and use an external charger. Indeed, if you get one of Overlander's Eneloop packs for it (which gives you a significant increase in capacity!), you will find it has a small Molex connector to plug into the Tx, and a separate JR type connector to connect to an external charger. Then you don't even have to disconnect the battery to use the external charger! Just make sure the Tx is "OFF" before you try and charge it! -- Pete Quote Link to comment Share on other sites More sharing options...
bert baker Posted March 9, 2017 Share Posted March 9, 2017 I blew the internal fuse in the transmitter when I plugged a futaba charger in JR have centre pin as negative Quote Link to comment Share on other sites More sharing options...
Steve Balaam Posted March 9, 2017 Share Posted March 9, 2017 If the worst has happened and you have blown the internal charger, it's a fairly simple item to replace. I upgraded my original battery to NiMh 2000Mah and replaced the internal board with an upgraded one. I think I got the parts from T9 Hobby Sport Steve B Quote Link to comment Share on other sites More sharing options...

That makes sense peter, I think you have it there matey. No such thing as ignorance in here , just questions and answers. D.D.

John Privett Posted March 9, 2017 Share Posted March 9, 2017 Posted by bert baker on 09/03/2017 20:28:47: I blew the internal fuse in the transmitter when I plugged a futaba charger in JR have centre pin as negative I'm not sure of the relevance here, Bert. The power supply supplied with the Taranis has the more common, centre-positive plug. But many sources state that the Taranis has a bridge diode rectifier between the input socket and the internal charger and so will happily accept either centre-positive or centre-negative. Even, I guess, AC? Just don't try and use an "intelligent" charger via the Taranis socket - that is likely to let the magic smoke out...

Or did you mean you tried to charge a JR tx with a Futaba charger? I assumed you meant you'd tried a Futaba charger on the Taranis and blew a fuse.

bert baker Posted March 10, 2017 Share Posted March 10, 2017 My mate put my tranny on fast charge for me, shame he used a Futaba adaptor and blew the fuse,,,,,,,,soz I didn't realise that some have a built in charger so no relevance Quote Link to comment Share on other sites More sharing options...
graham dallison Posted March 13, 2017 Author Share Posted March 13, 2017 Many thanks for comments, but just received replacement battery from Hobby King for use in Taranis. Only thing is I have to remove for charging. Cost is less than sending for repair, and will last longer between charging. Quote Link to comment Share on other sites More sharing options...
