Tip & How-To about Radio Communications

How to revive old Ni.Cad and Ni-Mh batteries.

Hello,

This is a hit or miss procedure so do it at your own risk. It sometimes happens that your above mentioned batteries go dead and your charger doesnot recognize them and shows an open circuit or similar. to reveive these batteries you will need a 12v Lead acid battery. connect the -ve terminal to the -ve and +ve to the +ve for approx 6-10 secs to each cell individually the cells should be warm to the touch and not hot. At this pint you should connect them to your charger and it should start charging them. most of the time it works but it is not foolproof method.

The light came on because the charger brought voltage up to full, but when you hit the throttle, the voltage dropped since the charger cant power the motor. While checking the wiring (which I assume people automatically do), bypass the power switch with a screwdriver or a jumper wire. If it works, replace the switch. Check the battery with a multimeter...you should get > 25.2v full charge, no load. If you get 0v, check the fuse in the battery case. If all of the above check out ok, and it's totally dead, you probably need a controller.

12 RES - Control Panel Dead With New Battery


If it won't start in manual, you have a short and/or a bad control board. Make sure battery polarity is correct, did you disconnect battery charger before removing old battery? If not charger can push DC volts over 20V and can damage control board.

Hello, have a 2003 XL 1200 custom that wont start,what is happening when you kick it over and it starts clickin then starts to die away like battery going dead. cheers Jes


I think you hit the nail on the head, Jes. Sounds exactly like your battery is going dead. Just to make sure, take the battery out of your bike and take it to an automotive parts store. Have them test the battery. They'll usually do this free of charge. If your battery is over two years old, it's probably bad.

Now, if you purchase a new battery, get the highest CCA (cold cranking amps) battery you can get. Also, consider the purchase of a Battery Tender or a Smart Charger that will connect directly to your battery via a short pigtail. Do not use a regular automotive battery charger. Put the pigtail on your battery and when you get of the bike, plug the charger to the battery. This will increase your battery life tremendously.

Good Luck

i switch on my phone and nothing happens


Hello. If nothing is happening you most likely have either a dead battery or a dead charger. Take your phone and your charger into any phone store and the tech. will check it for you. Regards, Joe

TX IS DEAD


The T3 will appear dead until the battery has SOME charge. A totally dead battery, even though plugged into a charger, will not let the T3 turn on. You mention a previous charger problem. Could be a bad charger, or a bad battery. Check to see if the charging light is on on the T3 when you think you are charging. If it is not on, try another charger. If it is on, you may have a bad battery.
