Suburban SW6 lights but drops out after 30+ seconds

Yeah I did the same thing, got side tracked by the 12 vdc present constant. I had taken a wire and applied 12 vdc to each coil and listened to the hard click and came to the concussing it was working OK and passed on that ... I had thought about checking resistance early on and didn't do it .... Should have ... lol

Tanks for your help anyway, good advise...
