Low voltage during engine start can cause the SAFE message, and low voltage to
the alarm could certainly explain the drop in volume.
But corroded cable connectors, battery terminals, and grounding wires could
cause the same thing.
So which is more evident? 4+ year old battery, or a rusted engine compartment?
the battery is 4 years old but the voltage indicator is at 12. so can we
rule out the weak battery? Rusted and corroded cable connectors, is that
easy to check or it has to be done by a mechanic.
