I have never checked how much amperage a solenoid draws. That being said, it should be only a few amps depending on if it a Ford or GM solenoid. A old school GM would be the most.What it is energizing is what is going to cause the most amps drawn. Modern permanent magnet starters will draw about 150 amps while cranking. That would be on a small block engine with 10 to one compression. The initial amperage draw would be about 20 to 25 amps more.
