GAUGE TROUBLE DIAGNOSIS
GAUGE TESTING EQUIPMENT:
A. One new OK tank level unit (constant voltage).
B. Three ten-foot lengths of #16 insulated wire equipped
with clip terminals at each end of wire.
C. One new OK panel fuel indicator gauge.
VOLTAGE REGULATOR:
The constant voltage regulator is common to both the fuel
and temperature systems, that is, one regulator is used to
operate both systems.
METHOD OF CHECKING:
1. If both gauges read considerable too high-- for example,
if the gas gauge reads up scale with an empty gas tank
and the temperature gauge reads up scale with a cold
engine, the constant voltage regulator is not working
properly and should be replated. (Check ground connec-
tions of the voltage regulator as grounding is essential to
the proper functioning of the regulator.)
2. If both gauges read too low, either the input voltage to the
C.V. regulator is below 5.0 volts or the voltage regulator
is inoperative and should be replaced. Check battery
voltage output before replacing regulator.
PANEL INDICATOR CHECK:
1. Disconnect lead wire at gas tank gauge unit.
2. Hook in a new tank unit. Grand tank unit. Place float in
empty position, Figure 103. Turn on ignition switch.
Panel gauge should read at (E) on dial.
3. Move float to full position, Figure 104. Panel gauge
should read Full (F).
NOTE: If checks 2 and 3 are O.K., both panel gauge and
lead wire are O.K. If checks 2 and 3 are not O.K., hook
up a new tank unit to proper terminal of panel gauge and
eliminate the lead wire from the panel indicator to the
unit from the regular circuit. Repeat empty and full
check. I f tank
check. If now operating O.K., correct or replace bad wire
between tank unit and panel gauge.
GAS TANK UNIT:
If there is any question about the tank level unit being
O.K., hook the tank unit up in series with a panel
indicator and a constant voltage regulator known to be
O.K. and a 6- volt battery, operate tank level unit by
hand and see if panel indicator reads empty (E) with
tank level unit float in bottom position, Figure 108, and
read full (F) with level unit float in top position, Figure
109. If the panel indicator and lead wire function prop-
erly with a new O.K. tank unit, but did not function
properly with the original unit, replace original unit.
NOTE: Be sure tank unit is properly grounded to gas
tank and also that the tank is grounded to the frame.
GASOLINE TANK
REMOVAL:
1. Raise car and place stand jacks under frame.
2. Drain the gasoline tank and disconnect the fuel gauge
wire and the fuel line.
3. Remove three Phillip head screws in rear compartment
and remove the sponge rubber retainer.
4. Remove the rubber grommet and overflow drain hose at
gas tank filler door.
5. Remove the two nuts and spacers attaching gas tank
straps to body crossmember and remove the gas tank.
6. Remove the gas tank gauge unit.
7. Remove rubber shield from gas tank inlet pipe.
8. Remove gas tank outlet pipe.
Installation:
1. Install gas tank gauge unit (use new gasket).
2. Install gas tank outlet.
3. Install rubber shield to gas tank inlet elbow (use new
clamps).
