Set the meter to ohms, and touch one of its probes to the negative terminal on your Dawn. Then, touch the other probe to a metal part of the chassis or engine. The reading should be near zero ohms.

A clicking sound is another indicator of an insufficient Dawn battery. This is due to the fact that the starter solenoid as well as other components require high currents of electricity, while the engine requires a lower current to function. This means that the battery will not be able to supply enough charge.

Water Damage

If you accidentally dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it is likely suffering from water damage. The chip's electronic components are protected by rubber seals but prolonged exposure to clean ocean or salty water could cause it to stop working.
