Common Complaint
Air horn does not blow, or sounds weak. Assuming the plumbing is
correct, we will check for tuning, when we refer to tune we are not talking
about adjusting to high or low tone, it is in tune or out, blows weak or
without the intensity you would expect from a air horn approximately
130db.
Procedure:
To tune a horn, fi rst check bushing threads exposed forward of sound
unit should be one or two in most cases. To tune, hold bell end fi rmly
with left hand and with right hand grasp complete sound unit and rotate
counter clockwise slightly, only enough to turn bell, in or out to expose
threads slightly forward of sound unit. A good starting point to tune is
one thread exposed, tighten bell up to sound unit and try, if sound is
not pronounced, loosen unit move slightly 1/8 turn in or out, and retry until sound is bright and crisp.
In some cases it becomes necessary to replace Spring, Diaphragm, or Gasket. Use Kit #1094.
On the Non-Adjustable style horns, Use Repair Kit #1681 for 1700 series and Kit #1607 for 1600 series horns. The only
other item to check on these models, is the bell seating into the sound unit and tightness of clamp.
1-1.8.1 Backup Lights
Backup lights are similar to vehicle backup lights. They engage when the motor home is in reverse to warn motor home is
backing up.
1-1.9 Landing Lights
There are three sets of landing lights. Two are on the left side of the motor home, two are on the right side of the motor
home, and two are on the rear of the motor home. They may be switched on or off by selecting one of three buttons marked
REAR LAND, LEFT LAND, or RIGHT LAND, on the panel just to the left of the main instrument panel on the dash. A common
use would be to aid owner in various operations performed such as loading the motor home, entertaining, or anytime light
is needed in that area of the motor home. The reverse landing lights will only operate while the motor home is in reverse or
neutral. They will not operate if motor home is in drive.
1-1.10 Spot Lights
The spotlights are located on the roof in the front of the motor home. They are operated by and on/off switch and toggle
switch used for directional purposes on the right hand side of the dash beside the ignition switch.
1-1.11 Vehicle Loading
The Federal Certifi cation Label, located inside and above the driver’s windshield between the sun visor mounting brackets
describes the maximum weight-carrying capacities of your motor home and for each axle, respectively abbreviated by
“GVWR” and “GAWR.”
The Gross Vehicle Weight Rating (GVWR) is the maximum motor home weight allowable with all systems fi lled and with
passengers and supplies aboard.
Each axle also has a maximum load-bearing capacity referred to as the Gross Axle Weight Rating (GAWR).
The load capacity is the difference between the GVWR and the actual weight. This means that the total weight of all food,
clothing, other supplies and passengers must not permit the load capacity to be exceeded.
To fi nd the actual weight, with the motor home fully loaded, drive to a scale, read the weight on the front, and rear wheels
separately to determine axle loading. The load on each axle should not exceed its GAWR. If weight ratings are exceeded,
move or remove items to bring all weights below the ratings.
