Alarn Module Tone

[pbyrne]

I replaced the alarm buzzer for a new buzzer as the old one was faint to non existant.  I replaced each terminal wire connection one at a time to ensure they went back to the correct location.

When the key is turned to ON but the engine is not started, the alarm is TONE, PAUSE, TONE, PAUSE.

Is this correct?  According to Catalina Direct it should be a solid TONE for low oil pressure.  But I replaced the connections one at a time, and I'm not sure what it SHOULD sound like.

Catalina direct does sell a new alarm for the engine panel that has two different tone patterns, one solid and one intermittent.  In the event you have the one with two tone patterns, it would appear you have wired it with the oil switch to the intermittent terminals.

pby : I don't know where you got your replacement "buzzer" (sounder) from , but I have always used "Radio Shake" to get my sounders from.  Unless you have one near you  - you can go on line to order one!! @ half the price !! I believe that you should have a steady tone!!

It does seem to be what happened, however I replaced each terminal one at a time to avoid it being wrong!

I got it from Catalina Direct.  It was a direct replacement by the 'sounds' of it, but it doesn't seems to have the same internal wiring.  I replaced each terminal one by one to avoid messing it up!

It is likely possible that the original buzzer had the wiring the other way round from the new buzzer.  If you look at the buzzer wiring diagram sticker on the back shown on the CD website, there is a P terminal and an S terminal.  Just guessing, but I would say that the P is pulse and the S is sustained.  If you trade your two wires on yours at the boat between the P and S terminals, you'll likely change what tone each switch makes.  There isn't a problem with changing them.  The P and S terminals are just the ground output.

Yeah they must have switched them.  I know it's not me, as I was very careful to do them one at a time in the same orientation as the original.  I didn't even remove the original until I had the wires switched over.
