Test an Ammeter: 24V DC 100A Loads

[bibs]

How can i test an ammeter with ratings 24V (dc) 100 A with any load?
This is just to check whether the ammeter works in the defined range. What kind of source should i connect to get a current of maybe 25 or 50 amps.

You can generate high current with a car battery shorted, for a short time, to a low resistance load, such as a few feet of low gauge wire, or a motor.
