2000 H3-45 Engine & Transmission inspection needed in Dayton Ohio prior to purchase

[RichardE]

The owner threw a lot of money to someone who did not know what they were doing. And he paid dearly for it.

Plan on taking the coach to Moscow IA, and let HWH sort it out. Their call in help is hard to work with, but if you will get the coach to them it will get fixed.

The issue now is the first shop did who knows what with regard to how it is supposed to be. And now the dealer has messed with it even more.

I would bet a lot of money that the slide is not physically jammed. Why? I have seen first hand how powerful the hydraulic system is on the HWH slides and what it will destroy going in and out. This is an electrical/limit switch problem in my opinion. The HWH brain follows a very specific algorithm. On slide out, the key is turned, a timer starts for about 15 to 20 seconds, the pins retract and the pin limit switches must tell the brain the pins are retracted, only then will the solenoids open to extend the slide. It is counterintuitive, but both the extend and retract solenoids open in extend mode. The room extends, the outer limit switch makes, and the pins lock again.

On retract, key on, seal deflates for 15 seconds, pins retract, pin switches make, floor drops, retract solenoid opens, room stops when in limit switch makes, pins extend, pump turns off.

You can stand on a stool, look over the slide with a flashlight to see if the pins are engaged. Even if they are not, the slide will not move outward while driving. HWH puts a locking hydraulic check valve in the cylinders to prevent that. You can stuff the foam sealer used for caulking, but I would just put tape on the seam, and plan on using some 3M adhesive remover to clean off the residue.

While you are all wound up, google how to read the codes on the Detroit and the Allison by blinking the lights.

Your ultimate question, can it be fixed? Yes. Can you fix it yourself. Possibly, if you will download the HWH documentation, take the time to study the schematics, and approach the troubleshooting methodically with a voltmeter.
