The voltmeter may be checked by running

STEACE-R Test 67 wtth the engine running.

The position in the center of the green area

of the volt gauge marked GEN is approx-

imately 28 volts.

that the coil in the

gauge may have a broken wire that only

opens when the gauge is heated up. If you

are having an intermittent

gauge problem,

leave the vehicle running for a while and

watch the gauge.

ff the charging system is ok, but the gauge

is reading full scale one way or the other,

you may have this type of problem.

Rotary switch has to be in the

RUN position
