I installed gauges in addition to lights, as well as piezoelectric buzzers in different sounds for various functions. For example, above the temp gauge I have two LEDs with different buzzers to differenciate the alarm
. One connects to a temp sender bolted on the cylinder head
. The other is connected to an Aqualarm flow switch to indicate if a plastic bag has blocked the intake, or that the seawater impeller has thrown a rubber fin. The two alarms tell me whether I need to shut down the engine
now, or can I wait a moment.
I also have a Racor
vacuum gauge, plus a vacuum switch to warn if the diesel
filter is clogging, warning me to switch over to a backup filter.
In addition, all alarms and indicator lamps have test buttons and mute switches inside the electrical
panel to reduce the stress when stuff happens.
