KW W900 low air alarm inop

1999 KW W900..when the PSI is below 60, I get the red idiot light on the top of the visor but no audible alarm.

However, if I turn the ignition on w/o the engine, I see the OIL idiot light and the alarm/chime does go off.

I suspect the alarm/chime is for several reasons and you then need to look at the idiot light panel to see what it's chiming for.

Since the light lights for UNDER 60psi, I presume the sensor is AOK
and since the buzzer buzzes for low oil PSI, I presume the buzzer is AOK.

Is there a separate buzzer or any idea why this doesnt buzz?

 

Ok. I wasnt sure as I never had a rig that only 1 of them worked.
any thoughts on how to fix/trouble shoot this?

The 1 buzzer buzzes so we know thats good
The 1 light lights so we know thats good
Since the light comes on at and out at 60+ the sensor is good

..whats left to look at or repair?
Faulty instrument panel thingy?

I did see some dipswitches on it and perhaps some combination of those does things like this (maybe?) but w/o documentation I can only guess.

 

Hawaii ? WOW!
I got married there, but can't drive there until they finish that bridge.

..I like the idea of a different buzzer. Something shrill maybe. But OTOH, I would like to know why something factory isn't working. I think I will keep asking around and thinking. If I can't get an OEM solution, then I certainly can drop into "Bozo Barn" (as we call it) and see what options I might have.

I hate things that don't work right.
-Obviously buying a used 1999 KW would cause conflict with that statement.

 

Ah hah...thats cool. Care to share each dip switch?
I saw this red switch thing last weekend when I had the visor area out.
Maybe 10-12 white switches?

I plan on doing this Sat early am. Its just too dam hot out right now and the rig is in the dead of the sun. NO SHADE

PS. Thanks

 

no, thats it...8-12 little dip switches.

Does it say UP/ON = buzzer?
DOWN/OFF = Silent?
