I purchased a 1988 hi lo which needed some updating. I am looking for wiring diagram and or owners manual on this

In the reference library there is a owners manual for an '87 and an '89 Hi Lo. Things didn't change much from year to year.The wiring diagrams aren't too good as to component location but will help out.

I don't know that you ARE going to find that schematic. I don't recall ever seeing the AC input to the converter on any of the wiring diagrams. There would be only three wires: Hot, Neutral and Ground.

odd it’s just not documented I have an AC wire about 15 feet long 20 feet long stored in a box that looks like it came standard equipped on my Hilow that stands out . I plug this in and was able to turn on my AC What I’m trying to understand is what else the AC goes into perhaps he goes to a converter that goes to the 12 or that could charge to 12 that’s what I was looking for

Mines a 81
Model 2181

If you're talking about the "shore power" cord (the thing you plug into a 120V AC supply, like at a full hookup campground, or maybe into a wall socket at home), it goes directly to the back of the Converter. The converter has only two functions:

1. It transfers 120V AC power directly to the interior wall sockets, refrigerator, microwave, hot water heater, and Air Conditioner, etc.

2. It "converts" 120V AC power to 12V DC charging power which is directed straight to the battery. The battery then powers all DC appliances such as the lights, top lifting, fans, etc.

Now if the cord you are talking about is the one that goes from the bottom half to the top half. that's what transports the 120V AC power from the converter to the Air Conditioner. I some trailers, like mine, it's "fixed". In others, you have to plug it in.

Wow,
Thankyou Jack you answered my questions I was curious if it would charge my battery while powering the accessories You explained it thoroughly .

JackandJanet · 05-06-2020, 05:57 PM

Yup, those two functions happen together. However, I've found, in my trailer, that there are two 30 Amp fuses that tend to blow in the DC charging circuit. These are sort of "hidden" in my Elixer converter, behind the accessible fuse panel.

I think I've blown those fuses by raising the top or, raising the connected trailer/tow vehicle combination with the tongue lift while having the trailer plugged in to shore power. Both of these actions put a very heavy DC power load on the battery and I think possibly that the heavy drain gets transferred to the converter, exceeding the 30 Amp limit on that circuit. So, I've learned to not have shore power connected while raising the top or lifting the truck/trailer.
