It is normal if the readings of fuel gauge are within the
tolerances of all length between "E" and "F" as shown in the
following table, against the standard resistance between point
A and B indicated in the wiring diagram when ignition switch
"ON".

OIL PRESSURE GAUGE
Oil pressure gauge (bimetal type) is operated by oil pressure
unit (bimetal type) located in lubricating system.
It is normal if the readings of oil pressure gauge are within the
tolerances as shown in the following table, against the standard
indicated pressure values on oil pressure gauge.
