Just looking for some clarification. I have an 89' 340 Sundancer with the systems monitor in place.
Does this unit only look for 12v from something and then trigger the LED ?
The unit I have is covered in red cement? so it's difficult to see what is going on. The unit itself has a ribbon cable coming out of it and then each wire is separated and screwed into a long strip with all of the devices that are monitored on it.
The issue that I have is that I can trigger the LED but the alarm won't sound. I have tested for voltage at the alarm and have nothing.
Is this circuit just simply looking for 12volts and turning on the corresponding LED and then supplying 12v to the alarm ? Just looking for clarification because if that's the case I could easily rebuild the whole unit.
I have tested with the bilge high water alarm (which is triggered and needs to be fixed). I have 12volts coming in from the labeled wire and that wire is jumped to the corresponding wire in the ribbon cable which also has 12volts. If I remove that wire the light will go out. This just seems to simple not to fix and upgrade.
The unit in my boat does not look like either of these - http://logicleveltech.com/searayboard.html
