Day 15 - Corvallis, OR

I think that I'm just about done.

The Raspberry Pi is set up and running. For some reason, the Tristar was absorption charging at 15.1 volts. Too high. I restarted the unit and that seemed to resolve the problem. It looks s supposed to be 14.8 volts Hmmm, I'll have to keep an eye on that. Fortunately, that's what the Trimetric is for.

The automatic transfer switch (circled in red) is installed and tested. It's purpose is to switch the outlets in the trailer between the inverter and shore power. Installation was pretty straightforward. One romex to the breaker (hot), neutral and ground in the panel and one romex to the outlets hot, neutral and ground which are isolated from the panel. And a third cord plugs into the inverter output. The breaker is 15 amps and that matches the 2000 watt output of the inverter pretty well. BTW, the refrigerator is on the same circuit so I need to remember to switch the refrigerator to propane if I don't want it to run off of the inverter. The transfer switch is in the same compartment as the EMS so I ran an extension cord forward to the inverter.

If you have an RV, take a look at the keys for the storage compartments. If it says "CH751" then you may want to re-key your compartments. That key is used by many manufacturers probably for the convenience of the dealers. Once I was able to physically measure the storage compartment locks, I was able to order replacements from Industrial Lock and Hardware ( They arrived in today's mail so I'll probably install them tomorrow morning. As you can see, I opted for the cylindrical keys just to be different.


  1. I have to offer a big, huge, grateful THANK YOU for dashing any dreams or aspirations I might have harbored about owning and maintaining an RV in retirement. *grin*

    I realize more and more each day that I want to find myself a simple existence with less concerns for the things in my life. Scooter, black T-shirt, a pair of jeans, boots, and a credit card. Do I need anything else???

    1. Just don't get a "classic". This one is a 2001 model. If it was new I wouldn't be inclined to drill holes in it...

  2. So, Richard, with all your technical improvements... will it fly? I mean, literally?

  3. Blah, blah, blah, automatic transfer switch 👍! 😁

  4. Yeah, I was able to follow along until this post. This was real Greek. But if it makes you happy and works, I behind you 100%. HA. I'm gonna park my trailer beside you one day and enjoy the diagnostics show. hehe
