- How the Circuit Works
Do not smoke while working on the fuel system.
Keep open flame away from the work area. Drain
fuel only into an approved container.
A thermistor is mounted in the fuel tank unit. When
the thermistor is cool, its resistance is very high.
When the thermistor is warm, its resistance
decreases. Fuel in the fuel tank transfers heat away
from the thermislor last enough to keep it cool so
the thermistor's resistance stays high and the low
fuel indicator lighl does not come on. When the fuel
level drops below about 2.2 gallons, the thermistor
is no longer immersed in fuel. Without the fuel to
cool it, the thermistor's resistance decreases,
allowing current to flow through the low fuel
indicator light and the thermistor to ground, and lhe
low fuel indicator light comes on.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
