All too often on these forums I see people throwing around the vague, non-descriptive word "solenoid". Can someone please define what they mean by solenoids? A solenoid (per Wikipedia) is a metal coil. However, I know that it can also refer to valves/gauges/God knows what else. I would be very appreciative if folks would use a more descriptive term next time they post. Instead of saying, "Oh, well it's probably a bad solenoid" please be more specific as that gives me very little information.
