Operation

This section provides information on the opera­tion and function of the controls, indicators and gauges located in the pilot/co-pilot compartment that are used in connection with the coach automo­tive systems. Figure 2-1 illustrates the pilot/co-pilot compartment, high-lighting the instrumentation and panels covered in this section.

Instrumentation

All essential operating controls and gauges used to monitor and control associated engine, generator and coach systems are located conveniently on and adjacent to the electroluminescent dash panels, figure 2-2.

Associated instrumentation, accessible on the bulkhead above the pilot, includes generator ON­ OFF switch, altimeter and diesel fuel filter moni­tors. Refer to figures 2-2 through 2-13 and the fol­lowing paragraphs for locations and functions of associated operating controls and indicators.

Pilot Control Center (Dashboard)

You are now seated in the control center of your new coach. You have control of all engine func­ tions , generator functions as well as all accessory functions at your fingertips.

Our new dash layouts for 1988 were designed for viewing continuity as well as function and beauty. You will notice as you drive that viewing angle changes only slightly from the road to any part of the dash.

The dash is divided into eight main panels, (fig. 2-2) which are the upper dash panel, lower dash panel, shifter panel, upper right hand dash panel, lower right hand dash panel, monitor panel, moni­tor control panel and inverter panel. The gauges, switches and warning lights installed in these panels will be explained as far as function and op­ eration in the following text.

NOTE: Some items operate at all times, some require the 12 volt master to be on, while others need the 12 volt master and the ignition on. Gauges marked with an * require the engine to be at nor­mal operating temperature for correct readings.

Upper Dash Panel

1. Engine Water Temperature - Normal water temperature should be between 180° and 210° for safe operation.
   • CAUTION: If the Engine Temperature gauge indi­cates excessively high temperatures, the engine may be over-heating and should be stopped to prevent damage. Allow the engine to cool before check­ ing the radiator coolant level.
2. Engine Oil Temperature - Gauge-Gives a constant reading of the engine oil in the supply line from the pump. The normal operating temper­ature is from 200°F to 250°F. If the temperature goes over 250° the engine may be low on oil or there is overheating of the cooling system.
   • CAUTION: Your Wanderlodge is designed to op­erate at ambient temperatures up to 100°F with no problems. If temperatures greater than 100°F are encountered, the operator must closely observe engine water and oil temperature and trans­ mission oil temperature to avoid over­ heating conditions. If overheating con­ditions occur at ambient temperatures less than 100°F, the cooling system must be checked and problem cor­rected.
3. Engine Oil Pressure - Indicates the pressure of the oil, not the amount of oil in the engine reservoir. This gauge will normally read be­ tween 50 and 70 psi during cruising speeds; and drop to a minimum of 5 psi when the engine is idl­ing.
   • CAUTION: No oil pressure, or low oil pressure readings (below 25 psi) when engine is operating at cruising speeds are trouble indications! Do Not Operate the Engine Under These Condi­tions!
4. DC Volts - Registers the actual voltage at the coach batteries. With the engine running, gauge should read14 volts (+ or - 0.5).
5. Alternator Charging Amps - Shows total charging current in amperes. With the engine run­ ning, total alternator output is shown. When parked, with a source of 120 volt ac, (outside power or generator), the gauge will show total output of the battery chargers.
6. Tax Axel Pressure - The tag axle sus­pension pressure is factory set at 60 psi on WB-38 & 40 coaches
   • CAUTION: Before driving check gauge to make sure there is pressure in the tag axle air bags. This is critical for proper coach axle weight distribution.
7. Air Pressure Front/Rear - The Dual Air service Brake Pressure systems are engine operated and supply independent brake system air pressure for front and rear service brakes and the parking brake. During normal oper­ation, each air pressure gauge reading will build up to 100 psi to 120 psi shortly after the engine is started. Note that, as a safety feature, the parking brake cannot be released until air pressure read­ings are at least 65 psi.
8. Fuel Level - Indicates the amount of diesel fuel remaining in the 300 gallon fuel tank. Note that the 12.5 kw generator also gets its fuel supply from the 300 gallon tank. This gauge reads only when the ignition switch is in ON or ACCES­SORY position. As a precaution against generator operation draining the fuel supply, the generator fuel pickup is shorter than the engine pickup. Sep­arate fuel filters are provided for each fuel line.
9. Low Fuel Light - When this light comes on it is an indication that the operator should be looking for the nearest refueling station.
10. Low Air Warning Indicator - This light is associated with a buzzer. These warn the driver that there is an insufficient supply of air (65 psi or less) to properly operate the coach. If the air pressure is low, when the ignition key is turned on, the light and buzzer will come on immediately. Both warnings will continue until the air pressure is built back up, or the ignition key is turned off.
11. Burglar Alarm Switch - There are two switches that turn the Burglar Alarm on and off. The switch on the dash is used when you are inside the coach. The weather proof key switch, outside the coach next to the entrance door , is used when you are going to be leaving your coach for awhile. Note that both switches operate independently of one another. If the Burglar Alarm is turned on at the dash, then it must be turned off at the dash. The outside switch works on the same principle.
12. A/T (Anti-Theft) - deactivates the starting system for protection against unauthorized cranking and theft.
13. Accessory - These BLANK positions may be used for the installation of additional switches and indicator lights for customer add on equipment.
    • CAUTION: Use existing panel holes for installation of additional controls or indicators. Drilling new holes will destroy the electroluminescent features.
14. Headlight Alert - When the ignition switch is turned off and the headlight switch is on, this red warning light, along with a buzzer , will come on. These will remain on until the headlight switch is turned off or the ignition switch is turned back on.

Lower Dash Panel

1. Speedometer - Indicates speed and ac­ cumulated mileage (odometer). This is a solid­ state electronic monitor, with an RPM sensor lo­cated at the right drive axle brake drum
2. Tachometer / Hour Meter - Indicates actual engine RPM (Revolutions Per Minute) when scale (0-25) reading is multiplied by 100. Idle RPM should be 600 and full load (uphill) 2100 RPM. HOUR METER shows number of hours engine has been in operation.
3. Transmission Retarder Temperature - Measures temperature of the transmission retar­der oil. If the gauge registers a temperature over the 330°F maximum safety range, reduce use of transmission retarder. See information on use of transmission retarder later in this section.
4. High Beam - The Blue Bird logo is illuminated when high beams are selected using steering column switch.
5. Accessory Warning Lights - These three (3) warning indicators light to alert you of the following conditions:
   • Water in Fuel
   • Suspension Dump
   • Level Warning
