Is there some special circuitry between the transmitter charging jack and the nicads? I made up cables to use with an expanded scale voltmeter, a battery cycler, and a dc charger. Funny thing I was able to charge, but could not detect any voltage at the jack. Took a Futaba transmitter apart and checked the voltage on the wires attached to the jack, and still nothing. My question is, what's going on and how can I check the voltage and cycle my batteries? Thanks, Bill Kuhl RCSE-List facilities provided by Model Airplane News.
