electrical converter

[kcamacho]

Hey guys.
      I have a 1975 Jayco pup and I would like to install a battery in it. Under the dinette there is a converter box with a switch that say battery. It Is made by Andover Inc. I would love if someone could help with a wiring diagram.
Thanks.

Can't help with a wiring diagram, except to say the mid 90s converters had 3 wires coming out the back. A blue 12v + output, a white 12v - output and a red 12v+ battery input.

The lights are all powered by the blue and white wires. The switch on the converter conv-off-batt determined if the blue wire's 12 v output came from  120v converted or from the 12v + battery input (red wire).

Most things were also tied into the safety switch triggered by the swing over sink.

Thanks for the reply. I will get in and take a look and some photos as soon as I get a warm day. I am not sure what wires come out of the converter. I know the trailer does not have a battery tray on the chassis but I also know the previous owner did not do any dry camping and probably removed it.

The battery tray is usually just 2 pieces of 1" angle iron run parallel to each other, across the trailer tongue and welded in place. The battery sits in a plastic battery box (obtainable from Walmart for about $10) and the battery box is held to the angle iron pieces with a nylon strap (that comes with the battery box).

From there, use a white 10G or 12G wire from the negative post on the battery to a terminal that is sometimes mounted on the bottom side of the frame. If there isn't a terminal, you could drill a small hole and use a self tapping 10-24 screw. Be sure to solder wire connector ends on all of your wires and use heat shrink to keep the moisture out.

Then run a 10G or 12G wire from the terminal on the frame, through a small hole in the floor of the camper (near the converter). Solder that to the negative wire on the converter.

Buy yourself a 30A o- 45A time delay circuit breaker ($5 at Autozone). On some of them, one side of the circuit breaker will have a connector that slips over the threaded terminal on your new deep cycle battery on others, you'll have to make a short wire from the breaker to the battery terminal (like the one in the pic below). On the other side of the circuit breaker, run a black 10G or 12G wire from there, through the hole in the floor of the camper and solder the end to the positive wire on the converter. You can also put a breaker switch in that line so that you can disconnect the power when the camper is in storage.

Be sure to seal up any holes that you drill in the floor with silicone sealer from top and bottom of hole.

It is not necessary to solder all the wire/terminal connections when hooking up your battery to the converter. There are plenty of good crimp type terminals on the market that when applied properly will last for the life of the trailer with no problems. A good grade plastic electrical tape can be applied where needed instead of heat shrink which is much more expensive.

Soldering the terminals will be a better way to go if you have the equipment, the right solder and know how...
