What does a hot solenoid mean?
When a solenoid is first energized, its coil receives a pulse of high inrush current that decreases as the plunger closes. If the plunger does not close, the high inrush current continues, which can cause the coil to overheat and burn out. Thus, a solenoid too hot to touch may not be overheated.
When to know if your solenoid is bad?

What kind of wire to use for solenoid?
If you want, you can use brown or orange cables on the high current end of the circuit, to distinguish them from the solenoid to battery connections. The color of those wires will depend on whether you are switching ON and OFF the negative or the positive cable of the device that you are going to handle with the solenoid.
How to test a washing machine inlet valve solenoid?
Touch one lead from the multimeter to a terminal of either the hot or cold valve solenoid, while simultaneously touching the other lead to the other terminal of the same solenoid. If the reading is infinity, then you can be assured the solenoid is bad.
How are the terminals on a solenoid starter connected?
One of the larger terminals is connected to the hot wire coming from the battery, the second large terminal is connected to the starter, the first smaller terminal (S) connects to the ignition switch, the second small terminal connects to either ballast resistor (R) or ignition coil (I) and is generally unused.
Can a bad solenoid be a sign of a bad starter?
