I am using a 5v reed relay with a coil resistance of 250ohms, and contact ration of .5 amps and nominal current 20mA.
I have the same relay on a breadboard and in a perf board and it seems to be soldered together the same way. When it is in the breadboard, the relay and diode on its coil works. On my multimeter I get a normal reading...(when I put the multimeter on ohms, one side gives a reading, the other does not) however this same circuit in my perf board, when I test the diode, i get a reading on both ends...meaning when I flip the + and - on the multimeter i get a reading of like 200ohms either way...when I take the diode out of the perf...the reading is normal again...the diode works.
Any idea what could be causing this?
