Check to be sure that the battery disconnect relay switch didn't get bumped and take the batteries out of the loop. OR are you sure that something wasn't left on and drained the batteries? Are you plugged in power with the shore cord? Check those things first............and then get back to me if you need more as all follow ups are included in our fee.
Try starting it in neutral.........
And is what?
Some testing may need to be done here..........and I have to leave for a few hours, so I will opt out and allow another tech to offer something. Not sure when that might be as weekends are busy here.
Hi my name is Robert..
Just checking in to see if you need more help on this? What engine and chassis do you have?
Normally if you have a ford engine you would have a ford chassis, but I suppose it is possible that you have a Frightliner chassis, normally they use the Freighliners on diesel pushers.
So it sounds like you have all the dash power? Also on the transmission do you have a shift pad or lever you have to move?
I will try my best on this, it might take some going back and forth which is pretty normal as you are my eyes in troubleshooting.
That's OK and makes more sense.
So do you have all the dash power? And does anything at all happen when you try to crank.
Make sure your oil and coolant level is topped off, cycle the parking brake and make sure the unit is fully in park.
Also do you have a test light or volt meter?
This to me sounds like a possible issue with the start solenoid. The engine will not crank over if it is not in park so that is why the other expert was asking, IF all the dash lights work and you have good battery voltage go to the solenoid for the starter and try smacking it a few times and then see if the engine will crank over. What I would also do is get a 12 volt test light and turn the ignition ON and probe each fuse in the chassis fuse box, should be on the firewall in front of the steering column, a test light will allow you to test the fuses quickly and see which ones have power. You can use the steering column to clip the test light to for a good ground.
Also I would see if the starter solenoid is getting power you should be able to bypass the solenoid and see if the engine cranks over, I can go into more details on that if you like but I might have a mobile tech try that if access to the starter solenoid is poor, as you might be trying to do this from underneath the RV.... Robert
Check that oil and coolant level as well... Robert
Sounds good, I have a feeling the starter solenoid might be the problem if you have ALL your dash power but I would check all the chassis fuses first, try tapping the solenoid, sometimes they can seize up and the engine will not crank.

Also brain storming on this, on some RV's if the slides are out it will prevent the engine from cranking, so if they are out run them in and see if it will crank over.... Robert.
I might cycle them in and out, also I found an article with another owner with a Workhorse that had the same issue, it talks about a few things I mentioned, it may be helpful, click HERE to view... Robert
Also if the unit sat be on the look out for any chewed wires, rodents can cause all kinds of issues if they chew on the wiring, have seen that before....
Good deal, I am glad you figured it out, IF you are satisfied with my efforts please feel free to select a rating, it is the only way I get credit for helping out....
