Starting problems on 2015 Thor Axis 25.1

This is the third attempt to post this. I am logged in and as soon as I try to submit it as a new thread it says I am not logged in and I lose everything I have typed. When I went to start to start my Axis 25.1 I just got a click from the solenoid. All batteries are fully charged and the chassis battery is also new. I have had no prior problems with it starting and I had driven it a week ago for a
couple of hours. I took the old starter off and got a new one, which yielded the same result, just one clack, no spinning or any other noises. The horn is loud. lights are bright so I think the issue maybe power to the starter. I checked the #2 relay which is located in the fuse box on the driver's side front, under "hood"
and it is good. All wiring and contacts are clean with no corrosion anywhere.
I am hoping someone might be able to suggest some other check to fix this.
Thanks in advance - fingers crossed!

Clack???? With new starter. wow!
First thing I would do is put a wrench on the crankshaft on see if the engine turns.
Then with the headlights on, try to start and see if they dim.
Don't dim, power not getting to starter.
If they dim then power is there but not enough, bad cable or battery cranking amps no longer there.

On my coach (ACE F53) relay 2 in the power distribution box (in the engine compartment) is the fuel pump relay; relay 4 is the starter relay.....but I don't know your Axis at all......just asking if you checked the correct relay with a Ford manual?


Also the "time out" for entering info on the forum can be a PIA (but they try to limit logons who look like they are not doing much I guess). I found if when you log on, check the "remember me" box.....you stay connected longer. Also use a word processor to draft your text first; then logon to the forum; copy and paste your text into the forum entry and post.

I can't get a wrench on to turn the engine but I know it will turn. I had the lights on and tried to start - lights did not dim - and it just did one click. This RV only
has 8k miles on it and I put the last 1k on and it runs great, as it should.
I am thinking it has to be a starter relay in the fuse box but I have tried switching
the existing starter relay with another same kind relay from another source and
that did not change anything so I think that relay is good. On my Axis it was 2nd
from the left on the back row and is black rectangle about 1" x 1/2" and 1" high.
the one for the windshield wipers was identical so I tried that one in the starter slot. No change. I saw several other starter fuses listed and checked those and all appear to be good. At this point I don't know what else to check - anymore suggestions are welcome! Thank you.

Where do you hear the clicking?

When you said clunk in the first message, was that a clunk or misspelled click?

Far reaching but..... Is the shifter lockout messed up? Try to start in neutral or wiggle the shifter while starting.

Hi, I am not sure if your coach is similar to mine in terms of Ford fusing but there is also a 10 amp fuse in position 9 of the Power Distribution box in the engine bay that is labelled as starter relay coil; starter ground relay circuit. From your description I assume your reay flips were regarding relay #4? Ther are a couple of old Ford starter circuits on a web link if you scroll down it that might be similar to what you have .....the one that seems to go through the PCM (Power Control Module) may be the more modern schematic to use. There is not much else to check if the fuses and relays are good; you replaced the starter itself......so connections of key cabling and the chassis battery is about it. Hope this link works as I have had some issues with them in the past.

Trkyte - the click is coming from the starter. Tried wiggling the shift lever and also in neutral but that made no difference. The starter was exactly like the original so I am sure it isn't a fitment issue.

Javelin - I did get the link you listed and it did provide some info but nothing I could use to fix the problem. I have been working on my own cars since my '57
Ford and have never run into something like this before - very frustrating.
I did try swapping every fuse and relay related to the starter with other similar fuses/relays but that didn't change anything. Like I said earlier in a post, this is
a newer RV with very low mileage and hasn't been in any floods here (Harvey) so
all the wiring and connections are in like new condition. This thing has been trouble free until I went to start it the other day - no warning on this issue.

If you can't get it going, you have free towing with Ford to an authorized dealer that can work on it and perhaps free fix. You can call the Ford number for repair.........don't have it handy and they will make all the arrangements for you. I had to do it once, when mine would not start. Turned out to be a vac. line leak. Yours is probably something simple also, but tough to track down.
Good luck
