JR XP783 Field charging Issues
It has been a few years since I have flown; 5 in fact, but I don't recall the issue that I am having now ever coming up before.
I have an ACE fast field charger that I bought approximately 7 years ago to charge my TX and flight packs at the field.
Thinking that my flight box battery was slightly undercharged I decided to use the Hobbico charger and battery from a friend at the field. The Hobbico charger blew the fuse in the XP783 when we turned it on.
First issue:
The fuse in the XP783 was a 250ma fuse. I dont recall ever changing the fuse in the radio but the other guys at the field who fly JR (one of which is a XP783) all have 3 amp fuses in their radio.
What is the correct fuse for this radio?
Second issue:
Why did the fuse blow?
Third issue:
Once we replaced the fuse, with another fuse (200ma) the radio would not charge on another Hobbico fast field charger or did not charge on the ACE charger in my flight box.
Fourth issue:
I replaced the battery in the radio after not using it for 5 years. The battery I replaced it with is a 940mah. Does the capacity of the new pack come into play here?
Any JR experts out their? I am quite familiar with basic electronics but this one has me a little concerned as I don't want to damage the radio set.
Thanks,
