The solenoid gets it's magnetism from the DC current passing through it. If there's the same voltage at the solenoid terminals when the engine is hot as when it is cold, replace the solenoid. If it's lower, find out why. If the solenoid has only one wire and relies on the mounting screws for a DC ground, that would be the first place to check. Unscrew it, clean the mounting surfaces, and reinstall it. Tight.
