CIRCUIT

These gauges are galvanometer-type

gauges.

It is conceivable

that the coil in the gauge may

have a broken wire that only opens when the

gauge is warmed up. If you are having an

intermittent

gauge problem, leave the vehicle

running for a while and watch the gauge. If the

system the gauge monitors is OK, but the

gauge is reading full scale one way or the other,

then you may have this type of problem.

Fill the fuel tank, if necessary,

to obtain a

reading greater than empty.

GAUGE

With

engine running, the oil pressure

should be approximately

psi

kPa)

psi (276310

kPa) at 2.000 rpm,

it

should

when stopped.

I

Make sure shift lever is in neutral before running

this test.

With the engine cold, the gauge should read off

scale to the left and, when warm, the reading
