Sender diagnostics: See Figure 18.0.

Lower the float to the lowest position to close the
contacts in the sender.

tacts in the sender.

ADJUSTMENTS:

ENGINE SPEED AND THROTTLE LINKAGE

1.

The engine should idle at 1,200 RPM:
See Figure 7.45.

Slower idle speeds will result in poor idle quality,
reduced flow of cooling air, and reduced oil flow.

Higher idle speeds will result in harsh gear
selector action and possible internal damage to
the transfer case.

2.

Top no-load speed should be 3,850 RPM:
See Figure 7.46.

Slower top no-load speeds will result in dimin-
ished performance.

Higher top no-load speeds will result in unsafe
operating conditions and possible over-speed
engine failure.
