testing engine on stand wiring ?

[dragraceer1956]

Hi, i'm new to this site and there is a-lot of neat stuff on here.I got a question that maybe someone can help me out with.I got a 24v engine out of a 2001 school bus been sitting for a long time so i threw it on my motor stand and put a new head on it. I want to test it on the stand but having trouble wiring the apps because it is on the throttle pedal and not on the side of the pump. I don't want to burn the pump up by doing something stupid for it is a new one.I have already had it running but only at idle i want to throttle it up but can't figure it out . Thanks Craig

This site will show how the APPS functions.Measure total resistance from the "C" & "A" pins on the existing APPS & go to Radio Shack to get a potentiometer to replace it with. Use a switch to replace the "Idle validation" section of it. On those schematics, you MUST use the "ISB" & not the "Dodge" wiring. It's on the "Left" side.

Another simple wiring diagram...

 

 

Now remember this is for the Dodge Cummins not the industrial which might have different pins. I suggest you swap over to a Dodge wiring harness and ECM before going to much farther.

The one I posted had the ISB wiring on it, at least for testing purposes.
