Hi My JVC DV camcorder powers on in rec mode but powers off almost immediately. It will record normally when connected to the AC adapter. I have discovered that if I place some insulation tape over the middle terminal of the battery (it has 3 terminals +, - & T?) it will work normally. What is this 3rd terminal for?. I have four batteries and the camera will not work on any of them. I can play tapes normally on battery and the indicator shows full.
Thanks for your help.
