On my 5th Relay from radio shack I must be missing something easy. I have tried placing the wire on the silver arm of the relay the one that moves back and forth between the two contacts. I have also scraped the gold contact and placed the wire there.
If I solder the wire on the scraped off contact point on the gold connector the IRO runs constantly with a very high pitched sound, the silver arm does not move back and forth and the neon will only light if it is not connected to the target battery.
If I place the wire on the silver arm that moves back and forth the neon will light and the silver arm moves back and forth only if I tap the (+) side of the source battery.
Radio shack has one relay left and I really want to get this to work. Where can I possibly be going wrong?
Thank you all so much!
I'll say you are missing something... Here is what it is supposed to do!

NEON only lights if a target battery is NOT connected! You do not even need neon at all, it's just there
to tell you the circuit is working if there is no target battery. The silver arm DOES move, but it moves
such a small distance, that it appears still. The noise is the indication of running! You can fix all your
other relays properly now. Put a finger in there on the silver arm, you will feel it vibrate. I did not check
all your other connections (as I do not have a diagram or relay in front of me) but this last post makes
sense, you had it but was looking for the wrong effect apparently! The source batt. negative is soldered
to the scratched off gold contact, the electrons enter there and energize the coil, then the silver arm
BREAKS the circuit, letting the backspike exit out thru the diode leg. You had it, just fix it back like that
and remember, the neon is only operating without a target battery!
