Systems Monitor Alarms Quit Working

[Prosideus]

Anyone experience this?

So I recently replaced the battery charger after it kept frying my batteries. Right before I did that, we were stuck out on the hook because the port engine would not start. I eventually got it started, but in the process the attempts to start without enough juice in the battery bank seems to have cause the systems monitor alarms to quit sounding.

Usually when I power on the engine switches, before starting the engines, two alarms (one for each engine) were constantly sounding until I started the engines. Now that does not happen. Additionally, when I test the systems monitor with the toggle switch, I do not get the audible alarms as I did I. The past.

Could the piezzo alarms be damaged? Is there an in line fuse I should be looking for? Can I simply replace the piezzo alarms, has anyone done this on the systems monitor unit? Any ideas/assistance appreciated.

Ok, so I unscrewed the systems monitor panel from the helm and behind it is a block of epoxy that encases all the electronics. I don't see anywhere that piezzo alarms could be functioning in that block, but I could be wrong. I have started looking around under the helium and do not find anything that readily looks like a sound emitting device.

Any help appreciated.

I stand corrected. The block of epoxy is screwed into the systems alarm faceplate. I took it off and there is the piezzo alarm. I blew it out, tapped on it a few times and viola - it is working again. Thankfully, because there is no simple replacing. Here is a pic. The white circle is the alarm.
