Won't turn over
I go to start my 1998 Dutch Star Newmar 300 hp and it will not start. One Jack is down and it will not come all the way up but I dont think that's the reason it will not start. All lights are on and batteries are fully charged. Where can I start looking. Thanks for any help.

Any lights on the dash? Do you have a battery-boost switch/button?
Will the generator start?

Since you don't " think " its the reason, I would get the jack up first. Then you will know.

Is it turning over at all??
Had you been working on it at all?
My coach actually has a toggle switch on the dash in the back that allow you to start the coach from the back. I accidentally hit it while working on the coach and ultimately found the switch was hit not letting me start the coach.

People sometime use the same terminology to mean the same thing.
Does "won't turn over" mean it will not crank or it will not start ? If it will not crank, does it try to crank (you can hear the starter engage but not spin the engine) ?
If the starter is NOT engaging and the battery is good (put a test light across the starter battery terminals and see if the brightness changes when someone else turns the key to START), you either have a loose connection or there is a safety/security switch inhibiting the starter.

no start
If it dosen't crank[starter turning motor]the neutral safety switch is in the transmission control module.Make sure the gear shift pad is lit up,wont hurt to take it out of n and put it back.

"lejamjr"......It sounds like there may be a jack interlock. As stated.....get that jack up first or at least jumper the jack up switch and trick it into thinking the jack is up.

Don,
While I guess it's possible that there might be some form of interlock with a "jack down" situation but, as an example, our coach, MUST be started in order to bring up all the jacks and fill the bags. Now, could the OPs coach be wired or setup differently than ours, of course it can, but is it?
OP,
I'm assuming this "No Start" condition is something new, correct? How long have you owned the coach? Has anyone done any work on it lately, especially in any of the battery area, starting area, charging area? It's a known fact that, bad or, defective grounds cause a very large percentage of electrical problems in any automotive product, or at least used to. With that being said, have you checked the ground cables where they attach at the frame. They live in a hostile environment for sure.
There's other potential spots, switches, neutral safety scenarios, and more but, always start with good connections.
Scott

On my RV the motor must be running in order to operate the leveling system. Yours may be different. I would try getting the motor started and then try bringing the jack up. You may have a bad battery, or bad starter. Do you have fuel? Hope you get it figured out soon at little cost.

My key needs to be in the acc position. I dont think the Jack's down have anything to do with it because I'm sure I've had it idling when all 4 Jack's were down.
So I was playing with the relays the same time my wife was trying to start it and it did start. After we moved it and turned it off it will not start again.

It was running fine when we put it up for the winter. I need a wiring diagram for the ignition system.

You will find that on the chassis manufacturers web site.

If it started one time after failing to start, you likely have a loose connection or relay preventing the starter from engaging.
If the starter motor fails to engage there are typically four areas that need to be checked to isolate the cause. These areas are:
• Starter Power
• Ignition ON Circuits
• Ignition START Control and the
• Start Relay/Solenoid/Starter
Look for relays with names like Ignition, IGN, Start, Starter, Engine Control Module, ECM, Transmission Control Module, TCM, Neutral Lockout, and Starter Lockout or similar.
In many cases you will find an identical relay in another socket that you can swap for a test. Sometimes just pulling and replacing the same relay can overcome a poor connection and get you going. By changing only one thing then testing you should be able to identify what was the stumbling block when it all of a sudden starts working.
These relays may be in multiple locations such as close to the batteries, under the dashboard, or in the engine compartment.
The task can be a lot easier if you can get the starter circuit schematics from the coach vendor and have the skill with a multimeter to identify how far from the ignition key to the starter the power and start signal is getting.
