18. Sender diagnostics: See Figure 18.0.
• Lower the float to the lowest position to close the
contacts in the sender.
• Raise the float approximately 3” to open the con-
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.
