Recently I finished up resto/modding a 1976 Airstream Excella 500 - our Aluminum Falcon.... You can see that part here:
But I never got around to installing a battery for off grid camping... Well after a few weeks of gatherings parts... I now have battery power.
As we all know (or maybe not) the older AS's like our 76 had an obsolete battery disconnect that is no longer made, or those that have them want an arm and a leg for them... So I upgraded and made my own... And while we can wire direct having the ability to disconnect from the trailer THEN remove the battery to work on is great.
Cut off the old connector
Here's a short list of what you will need...
our system had 6 ga wire so I kept with that.. And please remember this was to my situation and may be different than yours. At the moment an inexpensive battery (so I can learn) and leaving it in the factory battery box)..
1-2 feet 6 ga (or whatever ga you have in the trailer)
5/16 battery loops (or whatever size fits your particular battery),..
Vice grips or table mounted vise
Quick connect system from your local golf cart shop.
So I started off prepping and measuring the cable ends versus the quick connect tabs
Stripping the wire and adding the solder to the clip tabs (as I was out in the country I used a leveling brick and a pair of vsie grips, and my cooking torch)
Place 3/4 (ish) full of melted solder (or slightly over)
Do not let this cool too long and start heating up the wires switching to the solder filled tab and then back then press the wire hard into the solder while heating so the solder wicks into the wires - I wrapped the actual cables around the awning pole to cool, the cables in the battery box just keep them off the plastic...
The battery end to the quick connect
After the cables are mounted to the battery slide the battery in and click the quick connect together...
Now turn on your lights and have a beer...
