Are there any special mounting instructions for solenoids?
Electromechanical solenoids should be mounted on a non-vibrating surface such as a fender well or firewall. They should not be mounted on a surface that vibrates such as an engine, as this may reduce the lifetime of the component. Continuous duty solenoids should be mounted in an area that has ventilation, as the coil circuit normally generates heat. Orientation of the solenoid, i.e. bracket up, bracket down, or bracket at right angle to the ground does not usually affect solenoid performance. Electronic solenoids are much more rugged, because they have no moving parts. They also will stand up to an incredible one million On-Off cycles!
