Technical Support / Re: Valid fuse

« Last post by Al Postma on Today at 02:22:19 AM »

Thank you guys, I changed fuse F 46 and the keyboard came right up.  Thank you so much.  Now ... after the keyboard came up, I attempted to get the generator to move out and ... it moved and works well in and out.  Now I know the only thing that heals itself is the human body so I assume whatever was causing the generator to not move is still an issue and will pop up again.

Thanks again for your help, I really appreciate it.

Al,
Sounds like you may have lost 12v. Couple of items to check.. On the large PC board in the front electrical bay there are 3 large terminals (lugs) on the right side as you are looking at the board. The top one is House battery voltage, the middle is Chassis battery voltage and the bottom on is Gnd. Check to  see if you have voltage at the top 2. A drawing of the layout is on sheet 2 of of the 07 Contessa wiring diagrams in Coach Assist.
If you don't have voltage at one or both of the terminals check for a blown ANL fuse(s) in the rear run box (rear bay, pass side). Diagram is on pg 18 of 07 Contessa wiring diagrams.
if you have voltage F42 is for the front hydraulics so it should run the generator slide. (uses chassis voltage).

I can't get the generator to come out, might be a bad fuse there as well.  I changed fuse #20 and nothing changed.

Don
Your post states your working on a 2004 with a Cummins and your profile shows you have a 2006.
For clarification we need to know What year make  and model are we working on to get the wiring diagrams right
We need to know whether it's a engine no crank or crank no start.

With that said here goes.
You stated you have poor or low voltage to the ECM

1) First check the ignition side buss bar in the electrical bay to be sure the ignition solenoid is not going. Bad your looking to see if you have a good 12 volts with the ignition on..next check each of the ECM feed circuit breaker on that buss bar to verify it has good voltage going out .

2) depending on the coach in the rear usually in the back of the battery bay there should be an ECM power relay check it to make sure you don't have a bad wire or a bad relay.

3) check. The wiring around the battery area your looking for 2 or 3 fuse holders ( again coach dependant)  these supply direct 12 volts to the ECM and the TCM and can get corroded from the battery acids causing problems.

4) check all your battery cables and ground connections

Hope this helps
Eric

F20 is the Valid Air compressor fuse.  F46 should power the controller/keypad.
Have you checked the circuit breaker on the generator?

I had a 2008 Contessa, and I saved a screenshot of an old post here on the forum where another owner defined the Valid air leveling fuse as F20.

I have a 2007 Contessa with air only Valid levelers.  I have had a nightmare with the electrical systems since having been  hit by lightening.  I think I have the 120 volt working properly now, but now to the 12 volt.  My generator will not go out and the valid keyboard is dead.  Everything on the panel under the window(?) where the keyboard is, seems to have power.  I looked for blown fuses in the electrical cabinet below the drivers seat and didn't see any that appear blown.  Can someone help me by giving me the fuse number of the fuse for the Valid and the fuse for the generator out?  Thank you ahead of time.

One other thing, on our coach the Allison transmission keypad MUST show an "N" (Neutral) before the engine will attempt to start.

Since you indicated possible low voltage issue I'm assuming you've checked all chassis battery connections , especially ground wires. One suggestion would be to start the generator and get a charge going on the batteries - that should raise the battery voltage enough if you happen to be just on the edge of a low voltage issue due to wiring problem.

General Discussion / 2004 Cummins ISL 400

« Last post by Don Colapietro on May 30, 2024, 04:40:39 PM »

we are working on a 2004 Cummins ISL 400 which died on its maiden voyage. running just fine, then shut off... no spitting or sputtering, just shut off and would not restart. plenty of fuel at the filters. it has a brand new ECM and now shows a code for speed sensor. getting tired of throwing new parts at it. we know just enough to be dangerous. some of the DC voltages at the ECM seem to be low. HELP !  where do we look now?  Don Colapietro 239 940 6199  Thanks
