2nd Gen Non-Engine/Transmission Has anyone ever adjusted the clutch switch...

[klenger]

... so that the switch changes state at the top of the clutch travel instead of at the bottom? Reason wouild be so that the cruise control will disengage before the clutch disengages so that the RPM's don't run away.

RPM's

What switch are you talking about? I do have the problem with the RPM's can run off with cruise still enguaged. Eric

Same problem with mine occasionally.

Kleger,



I don't think that you can change where the switch gets activited at without a total redesign of the clutch pushrod and master cylender.



Eric,



The switch that Kleger is referring to is the "Ralph Nader" switch which requires that the clutch peddle be fully depressed inorder to start the engine, that is unless it has been disabled and I don't know anyone that would ever do that.

If you adjust it that way, then when you start the truck , the switch would be in such a way that you could still have the clutch engaged when you crank, and start the motor.

I'm not a big fan of clutch interlock switches, and I have disabled them on cars in the past, but I don't think I would want to disable the one on my truck. There would be no stopping it if you ever started it in gear!!!

My Volvo 850GLT apparently had 2 switches in the clutch linkage. The first required the clutch to be fully depressed to start the engine. The second would kick off the cruise control as soon as you touched the clutch pedal. As Ken said, wouldn't that second switch be nice to have on these trucks?

If one could adjust the switch, you still couldn't start the truck with your foot off the clutch. You would have to push it far enough for the switch to toggle. I doubt that I would try to start it with the clutch part way in. I am more concerned about over-reving the engine downshifting with the cruise on.

I guess it's the advantage of an older rig before Dodge started skimping, on my '95 I just have to barely tap the clutch pedal to disengage the cruise, the clutch doesn't disengage. I've never checked it out but always assumed there were two switches.

over revving

You will never overrev the engine just by pressing the clutch in. These engines are rev limited by the injection pump. Pushing in the clutch while cruise is on is nothing more than a minor annoyance, In fact, the engine controller will disengae the cruise automatically when the revs increase too quickly.



You can lay a brick on the pedal and walk away. The engine will run at maximum RPM's as long as the fuel lasts without damage. In fact, wide open throttle with no load is what Cummins call "'high idle'.

My 96 had one switch and it is currently in the tippecanoe county land fill. it broke, and I pulled it out and wired around it. Yes the truck will start in gear and spin tires on gravel in the process.

I'm trying to figure out why/when you would depress the clutch pedal BEFORE touching the accelerator or brake pedal when on cruise control

Oddly enough, shifting from 5th to 6th, just wanting to coast (no need to brake yet) the light may change to green before I get there.

When I downshift to climb a steep grade, especially when towing.
