This issue occurs with older batteries, particularly when they haven't been charged for a long period of time. Multimeters are a good tool to test the conductivity to determine if the battery terminals have corrosion. Set the meter at Ohms, and place one probe against the negative terminal of your Dawn. Then, you can connect the other probe to a plain metal part of the chassis or engine. The reading should be near zero ohms.

A clicking noise is another indicator of a weak Dawn battery. This is because the starter solenoid and other accessories require high electric current, while the engine needs a low current to function. This means that the battery cannot provide enough charge.
