Sounds like it’s oil in the vacuum supply.
Here’s a TSB on that:
http://dodgeram.info/tsb/1996/24-16-96.htmYou’re free to assume that all 3 symptoms stem from a single cause.
I suspect there is more than one issue.
Start with this:

http://dodgeram.org/tech/dsl/troubleshooting/12v_trouble.htm
Then look at these:

http://www.cumminsforum.com/forum/94-98-powertrain/2272202-1995-12-valve.htmlThe reason i belive there caused by one thing is because all three things happened at the same time .
Your first post only mentioned the HVAC and RPM gauge going out.
The next day you posted
[quote=”Accord” post=188696]Now its doing that plus it wont go past 50 mph . hows the hvac effect all of this ?[/quote]Which led me to believe that the issues were sequential, rather than occurring all at once.
If you read the very first link, it describes a problem caused by a missing check valve letting oil go places it shouldn’t.
I’m not familiar enough with the setup to tell you if or how all 3 are linked but the lack of a check valve at the very least causes the 1st 2 problems.With all the linked pages, you should be able to sort out the cause of the speed limitation, if it isn’t stemming from the check valve problem.
Thank you for youre help man . ill be working on the truck Saturday . ill post to let know if this works .
Well i went through the links yesterday and saterday well working on the truck . i could not finding any thing that worked . then this morning it stoped chargering. I tryed three different alt’s none made a change . im really stumped on this one.
Did you check these from my 2nd post’s 2nd link?
Voltmeter low, battery not charging
◦Intake heater stuck on (diagnosis page)
◦Engine speed sensor failed (the tachometer will also not be working)
◦Alternator failurefrom
http://dodgeram.org/tech/dsl/troubleshooting/12v_trouble.htmDon’t know how you could actually test the speed sensor aka crankshaft position sensor.
This is what Rockauto lists
http://www.rockauto.com/en/catalog/dodge,1994,ram+2500+pickup,5.9l+v8,1095779,ignition,crankshaft+position+sensor,7196This is a similar issue
http://www.cumminsforum.com/forum/94-98-powertrain/371548-crankshaft-position-sensor-aka-ess.htmlLet us know how you fare.
ok i found the issue . after reading on the dodge cummins forum i found a guy with all the same issues . it turns out that if the crank sensor is bad it will not charge the battery’s the a/c will not work the rpm will not work the over drive ether . thank you bonnieman i found it through youre link.
