Coach won't start, need assistance

Coach won't start.  No power going to ignition or dash lights when key is turned.  Any suggestions.
Thanks, Mike

Do you have a volt meter? Check start batteries. Have you tried the boost switch?

Look at big silver solenoid on left of fwd pass fuse panel, should have 12 volts on both big terminals when key on.

Are you talking about the large wiring harness behind the cover in right side of dash in front of entrance?

I don't see any big solenoid, just wiring terminals, no fuses at all.

solonoid looks small can with two big and two small terminals on it. Should be left side when you remove the panel.

all those small square things with a wire on both sides are fuse/ breakers.

Ignition Relay has larger size cable attached and is usually bottom center on the big circuit breaker panel in front of the co-pilot chair.  This relay is likely the problem or the ignition switch is the problem.  When you turn the ignition key on, it activates the important Ignition Relay, which powers dash, etc.
Also is door 'salesman' switch accidently turned off.  Cycle the switch handle.

Unless a solid state solenoid has been fitted, you will have an ignition solenoid like this one under the lid on the dash. Amazon.com: Cole Hersee 24213 12V 200A Continuous Solenoid: Automotive

It will have the largest cables to it. There will also be a ground close by to attach the test light or meter to. One side should be "hot" and with the key on, both hot.

Check engine batteries at the cables leading from the batteries not just the posts. If any doubt, pull the cables off and clean including the battery posts. Many times this is the problem.

As Berry says, make sure you didn't accidentally kick the "salesman" switch. Cycle it.

I am a little confused. What does salesman switch have to do with starting the coach. In all my coaches, engine and engine start system is completely separate from house system and coaches will start with salesman switch off.

Salesman switch should Ave no e;;EMC on engine start - but solenoid and ignition switch in that order likely culprits.
You have that solenoid somewhere, keep looking

First thing is make sure your start batteries have full charge.

Thanks for all the help.  Up and running, at least to get me up to my working campground.  Still believe it is something other Thant he batteries, as they all checked out ok.  Will replace the solenoid relay when I can later this week.
Thanks again, Mike
