To check if your battery terminals aren't corroded, you can utilize a multimeter to test the conductivity. Set the meter at Ohms, and place one of the probes against the negative terminal of your Dawn. Then, you can connect the other probe to a plain metal part of the engine or chassis. The reading should be near zero ohms.


Another indication of a weak battery in your Dawn is a clicking sound when you attempt to start the engine. This is because the starter solenoid and other accessories require a high amount of electric current while the engine requires a lower current to function.
