Naim,

From your picture I see two or even three possible issues:

1. The battery holder itself. It seems your is of low quality and might have contact issues.
2. Bad soldering job to the battery holder.
3. The red wire next to the connector - where I put the yellow arrow pointing at it.

Yes you can change the wire but you will also need the connector. Once crimped, the terminals of the connector can not be reused (recrimped). You do not list your location in your profile so I can not give you advice on where to get the pigtail (connector with the wires already crimped).

I'd still recommend that you get rid of the battery holder and get a rechargeable pack, preferably made of Eneloops or other brand NiMH Low Self-Discharge cells.

Those battery holders are about $5 to $10 for the real JR product, I would suggest getting a new one. It will come with the correct plug on the end to just plug into your radio. Alternate would be to buy a rechargeable pack for that radio, a little more expensive but again it should come with the proper connector attached.

After looking around it seems the AA holders for these older radios are pretty much gone. Next best bet would be to buy a generic holder from Mouser or Digikey and put the correct connector on the end.

Thanks for the advice. Yes, the connector is the problem if i change the wire. I dont know how to find it in Malaysia as the tx is very old one. Peoples now moved on 2.4ghz transmitter. I think that I should do that too but I'll keep this Quattro. =)
Again, thanks everyone. I'll try to fix it.

On your picture the red wire seems damaged approximately 5 mm from the plug - where the yellow arrow points.

That connector is more popular than you may think - every old and current JR and Spektrum radio uses it.

There are two kinds of JR connector: old black and newer white.

Just looking at the fuse isn't good enough. It needs to be replaced or at least tested with an ohmmeter.
