Something interesting...

       Remove this ad - become a site supporter!
I was checking out some battery packs today and decided to check one of my JR heavy duty switches. When the switch is turned on, I get normal pack voltage, when I turn it off, I can still see 0.04 Volts coming through the switch. Haven't checked my other switches yet, but was wondering if anyone else has experienced this?

I know some of the airtronics switches (the ones for PCM receivers, that have a different coloured lead) let a tiny amount of "juice" through the switch to allow the failsafe settings in the receiver remain programmed. If you use a normal switch you have to reset the failsafe (from the transmitter) each time you turn it on/off.

Perhaps the JR system is the same? I dont remember reading anything about it in my 10X manual but I will have a look.

Hi Jason.

Sounds like you're using a digital voltmeter to perform this test. Unfortunately this is not a good instrument to perform tests like this. Voltage doesn't "flow", current does. In fact, it's not unusual to see small "float" voltages on essentialy open circuits. A better test would be to determine if there is any current flow from the battery while the switch is off or disconnect the switch and check the resistance through the switch in the off position.

HTH, Jim.
