I bought a 89 Holiday Rambler 5th Wheel they were going to remodel and have taken the thermostat for heater, The lights on the wall and what ever else not sure what else .There are wires sticking out of thr wall above the entry door also on the opposite wall .Just to give an idea of what I'm dealing with 1st how can I find weather I have a inverter or a converter and how can I check to see if it works or not . I worked for Western RV in the 80s to mid 90s i know how to do trim install windows replace panes and everything on the exterior walls but when it comes to interior I'm not good I have a basic understanding of wiring 12v and 110v any help will Be greatly appreciated Thanks in advance H.A.G.

Almost any RV manual is just a collection of the manuals that the appliance manufacturers put out and any other information is just about useless.
For that year RV I suspect you have a converter and not an inverter unless the previous owner changed it out. That is how most RV's of that time were supplied.

We have a longtime member, Chris Bryant, now retired from his RV service business, who has generously provided a link to many manuals, both RV's themselves and appliances used in RV's, on his company website. You can check out the various categories on his site
here.

You would probably be best served by looking up the model numbers of the various items in your trailer and then searching for the manual for each item.
Good luck. 🙂

Check the battery voltage, plug in the RV and if it goes up the charger is at least partially working. Follow the heavy battery wires to the charger and research the model - if it exists. If the charger has AC output wiring then you have a charger/inverter. Turn on the inverter and if you have 120V AC output it's working. This all assumes you have batteries and they are OK.

Highly recommend you post on a HR board for help and you might even find wiring diagrams.
