LOWER RADIATOR HOSE HEATER OPTION - USE AND MAINTENANCE
Improper use of the lower radiator hose heater could result in damage to the engine or
personal injury. Do not modify the location of the lower radiator hose heater.
The following points should be followed when operating a unit equipped with a lower radiator hose heater.
•
Ensure the cooling system is full of the proper mixture of water and engine coolant before each heater use.
•
The heater is designed for all-night operation, however, 2-5 hours of heating just prior to starting is usually
sufficient for proper engine starting.
•
The unit must be level to maintain proper orientation of the heater while it is in operation.
•
Use only an undamaged, outdoor rated, three-prong grounded 120VAC extension cord with a minimum
amperage rating of 10A. Connect the cord to a properly grounded 120VAC, GFCI receptacle.
•
Before starting the engine, unplug the extension cord from the power first, then unplug the heater cordset
from the extension cord.
TROUBLESHOOTING THE LIGHTS
THIS UNIT USES HIGH VOLTAGE CIRCUITS CAPABLE OF CAUSING SERIOUS
INJURY OR DEATH. ONLY A QUALIFIED ELECTRICIAN SHOULD TROUBLESHOOT
OR REPAIR ELECTRICAL PROBLEMS OCCURRING IN THIS EQUIPMENT.
MAST LIGHTS ON BUT THE LIGHT OUTPUT IS LOW
1. Fixture and/or lens is dirty. Clean reflective surface inside fixture and both inside and outside surface of
glass lens. Use mild soap and water to clean lens. Other chemicals may have an adverse effect on the
glass.
2. Bulb worn due to normal use. Replace bulb.
3. Check the mast coil cord, mast junction box and mast light connections.
4. Generator output incorrect. Incoming voltage should be 120V +/- 5V. If the voltage is incorrect, adjust
the voltage regulator.
5. Low transformer output. The voltage from the transformer should read approximately 400VAC as the
light "strikes" (induces an arc), then drop and slowly rise back up to stabilize at 240-260VAC. On quick
disconnect models, measure across the junction box terminals when the light is unplugged. On hard
wired models, remove the mast junction box cover and insert the wire probes into the connector blocks
for the light and ground. If proper voltage is not achieved, perform capacitor check to determine if the
capacitor or coil needs to be replaced.
If problems persist, contact Magnum Power Products LLC Technical Service at 1-800-926-9768 for assistance.
TROUBLESHOOTING AUTOMATIC SHUTDOWN CONDITIONS
Allow engine to cool before performing any troubleshooting procedures. Contacting
the engine when it is hot will cause severe personal injury.
LOW OIL PRESSURE SHUTDOWN
1. Check the level of the engine oil with the dipstick. The engine controller will shut the engine down when
the oil pressure is less than 15 psi (103 kPa). Add oil if required.
2. Visually inspect the engine for oil leaks.
3. If the oil level is good, restart the unit and verify the loss of oil pressure. Shut the engine down immediately
if the oil pressure value does not read 5 psi (34 kPa) within five seconds.
