[QUOTE="travisstorma, post: 3827010, member: 24683"] Probably completely normal. As the magnetic field collapses after power is removed from the coil it creates a high volt low amp spike. You can likely put a diode across the contacts reverse biased to get rid of that. Many relay circuits have a diode built in to clamp that voltage spike from the collapsing magnetic field as it will damage electronics. [/QUOTE]
