2001 Damon Ultrasport, cummins 275 hp motor on a freightliner chassis. I just installed the 2 chassis batteries after charging them up and it won't turn over, nothing. I get all the lights on the dash and after they all go out, the "low Air pressure" stays lit. There isn't any air pressure at all. The manual trouble shooting to add air from an outside source but it fails to explain how to do it. Bare with me, I'm fairly new to this class A.

There are a few interlocks that may prevent your engine from starting, like slides out, etc. EVery coach is different but you may go through a check list to make sure that EVERYTHING is in the starting position.

Look around where you did the battery work. Look for a cable that may have been dropped.

Took pics before disconnecting and everything is where it should be. Slides are both in.

Bare with me, I'm fairly new to this class A.Sounds like the connection - clean and reconnect when you check the batteries to be sure they are charged fully.new batteries ?when did it last start? My guess is bad connection or bad batteries.Let us know how it goes.BOL,

If it was ok before you changed the batteries it should be a wire not connected or one connected to a wrong terminal. Possibly shorted and blew a fuse somewhere!

Update. Went over with my cousin and we started with the simple first. Had him go under and tap the the starter and boom, started right up. I'm happy, just a bummer I couldn't get under there myself.

Usually just means a stuck brush in the starter from setting.

Have you put a meter on the starter solenoid?

The prints I got show all of them. The 1st print they sent me didn't show any so I replied to their emailed and explained what I needed. The next day I had 4 really nice prints. To small to read, so I took them to a print shop and had printed on 24x36" paper.

The diagrams are nice, but they don't really tell you where the components are. FL can tell you that, too.

Do you have a voltmeter? If not you are trying to solve an electrical problem by guessing. What are the voltage readings at the battery and at the starter when holding the ignition in the start position?

With my back issues, I have to wait for the weekend when my cousin can help me and then I have to wait when it ain't raining or he won't go under the mh. lol. But that's in the plan, but did notice corrosion on some of the cables and will also look at those also.

I got ahold of freightliner and asked them for wiring diagrams for my 2001 ultrasport/xcs chassis. They sent 4 to me, front to rear. If anyone needs them to find what wire goes where, call their support number or pm me and I'll pass them along.
