1989 Fleetwood Flair - 12v Redo

Hello Everyone, my first post...I hope this is not a "Dude, do your research!"

I have a super cool (to me) 1989 24' Fleetwood Flair Class A motorhome. The electrical system, both 110vac and 12vdc were hacked before I bought it. In fact, I was such a newbie that I didn't even notice that someone had removed the 12vac converter. Ugg!

I have been remodeling this motorhome for the last 2 years and I am ready to address the electrical system.

I plan on staying with the 2 deep cycle batteries but I cant help but believe there are better battery isolators, etc... that i can install to improve my system. I do have the original electrical schematics (from Fleetwood thank you) but I was hoping someone has done a reconsideration of the 12vdc system that still includes the dual batteries, shore power, generator, and solar? I also still have the original Intellitec battery isolator but I am not sure it even works?

Thank you for any suggestions you might have.

Dan

We have a 96 Flair and upgraded the original converter with an Intelitech multi-stage charge profile. https://www.amazon.com/Progressive-D...53278941&psc=1 It made a drastic difference in how long it took to recharge our batteries, off grid. We highly recommend one.

We also upgraded our rig from 30A to 50A. You probably will not need to do such a drastic change, as I'm sure only have one roof mounted A/C. We have two, and kind of needed the upgrade.

If you are not boon docking extensively, and if you have 4KW generator on-board you are good. We still have our 2x 6V batteries. We are planning on doing a lithium and solar upgrade, as we want to extend our boon docking from 3-days to 2 weeks or more.

In regard to the previous owners (monkeying) with the 120 AC and 12 DC wiring, and associated systems.... So sorry to hear that, but glad Fleetwood gave you the basic wire schematics. Have heard from others (recently) that Fleetwood is not doing that courtesy for old customers any longer.

The good news is running new Romex is tedious, but doable. Also good news is Fleetwood did a good job of making the rigs repairable. Good success and post some pictures of your work.

Without knowing the original design for this particular brand and model it is hard to give much advice.

Thank you for this.

I am happy to share what I have from Fleetwood if anyone is in need.

I will see if I can add some pictures and make this a little easier to understand but I figured everyone had upgraded their motorhomes with all the cool gadgets out there. Especially a replacement unit for the intellitec battery isolator controller??? That unit gives me the most concern.

Hi Dan I would welcome any schematic info from Fleetwood. I just bought a 1991 Fleetwood Flair and am looking to upgrade the electrical with solar add-ons. I found the manual online but that have very little schematic details about the electrical system and my model's part numbers. We're tackling the AC now...although its draining but necessary. Again I welcome anything you could share and say Thanks in advance. This board is worth its weight in keyboards LOL
