SOLVED!!!
Thanks everyone for all the suggestions and help. The annoying buzzer was
easily found once I was able to un-attache the dash cover and expose the
wiring. The buzzer appeared to be wired to the "Low Fuel" TellTale light
using very thin wires. The buzzer was exactly where I suspected it to be;
pressed directly against the plastic shroud carrying air from the
HVAC system, which was a perfect resonator, amplifying the noise to an
uncomfortable level.
I cut and insulated one of the wires leading to the buzzer, and that
immediately killed the offensive gremlin. The Fuel Gauge (and all other
instrumentation) still displays correctly. Those of you that reported that
our coaches have only a low fuel warning light, but do not have a low fuel
buzzer were correct. This small but loud buzzer was clearly a PO
modification.
We will be taking the coach out for a run this weekend. It should be just
far enough to lower the gas tanks to the point that should trigger the low
fuel warning light, as it has done on those rare occasions when stretching
out the miles before filling up with fuel, seeking better fuel pricing
further on down the road. These past experiences have set off both the
buzzer and the warning light. It is interesting that this current
malfunctioning only affected the buzzer, without the ever turning on the
yellow Low Fuel TellTale warning light.
I'll report back on how lowering the fuel on this upcoming trip affects the
warning lights.
Special thanks go out to Steve Wienstock, Carl Stouffer, and Jerry near
Virginia Beach, for explaining how to get the dash off. And yes, someone
had already cut away the material in the upper left corner, making the
reinstall a piece of cake!
