2. Defective temperature
1. Install 40 ohm resistor
sending unit between temperature sneding
unit and ground (disconnect
from unit). If dash unit reads
full scale, replace temperature
sending unit.
3. Open wiring. 1. Follow corrective action as

4. Disconnect the tank unit lead wire (light blue with
black tracer) from the tank unit.
An gas gauge reading can normally be
found result from a poor grounding condition
within circuit. Using the procedure as outlined
below lead to the correction of the inoperative
reading replacement of either the tank unit
or the unit.
5. Connect stock tank unit; ground unit, and
operate manually.
6. If the dash unit shows a correct reading, then
replacement of the tank unit is required as the cor-
rection.
1. the gas tank (ground) strap is prop-
erly secured.
A correct reading will be one which resembles the
movement of the manually-operated tank unit.
2. Make’certain the ground wire (brown in color) for
gasoline/ and temperature gauges is properly con-
nected
the windshield wiper motor and is secured.
(This wire is also common for the heater
blower
7. If the dash unit does not show a correct reading,
then its replacement is necessary.
If the procedure does not produce a satisfac-
tory reading, an attempt to isolate the defec-
tive i.e. tank or dash unit should be made.
3. a tank unit from parts stock.
