I want to fit audible alarms for high coolant temperature and low oil pressure. My Moody 35 currently has warning lights on the engine panel in the cockpit – would someone please recommend a simple system to add audible alarms.
Just wire your buzzer across the warning light bulb, buzzer will then operate with bulb.
You will need to check which is positive on bulb, to match up buzzer leads, normally a pos feed and a neg side to sensor on engine.
