Wiring reed switches to the Universal Relay (item #7244). One of the blue wires goes to each one of the reed switches. The yellow wire on the universal relay goes to the yellow power source. The remaining wire from each reed switch goes to the brown wire of the power source seperately. The universal relay is doing nothing. What am I doing wrong? If you have a wiring diagram let me know.

Hi David, By all accounts that is correct, as per the attached image. You may need to confirm the solenoid is operating correctly with out reed switches. Test, prove, test. If the solenoid is opperating with out the reed switches, test the reed switches using a multi meter, or a simple light bulb circuit. Does the magnet close the reeds, and complete the circuit. You can always here the reed switch click when it closes. The reed switches can be a bit fussy in there alignment with the magnet, so care with alignment may be necessary. Is there a break in your power supply circuit, check you have correct voltage. I am using reed switches in the same manor, and have no problems operating solenoid relays. Cheers, Brian.

Hi David,
Just to offer an alternate troubleshooting approach.
If you have a voltmeter you can measure from brown to blue and expect to see about 16 volts with reed open (no magnet). If you don't see the 16 volts then you have an open relay coil or open wiring or bad power supply.
When you pass the magnet correctly over the reed the voltage should drop to zero. If it doesn't drop with the magnet pass, and it's all aligned properly and close enough, then you have a bad reed switch. If the voltage drops but the relay contacts don't switch you may
have some internal mechanical problem or the coil is bad in that it isn't creating enough field to move the solenoid. Keep in mind that you only want one reed actuated at a time and you will need to determine which switch will cause the relay contacts to change
from whichever its present state is.
I don't have any direct experience with these relays so I'm not sure if they can be energized for long periods or if they just expect a momentary type of actuation. Perhaps someone here can answer that, but just to be safe I would stay in the momentary regime just in case.
