The Ambassador has several non VAP approved exterior openings.
I removed the 110vAC water heater and the original furnace.Â These both left rather large openings.Â I plan on replacing these with a combo unit from Precision Temp, an Ambasador contributor.
I also removed the original black tank vent on the roof because it was attached to a rubber hose in the wall that was rotted.Â It also would not work with a modern toilet.Â The original vent for the black tank came from the base of the toilet.
So I spent the day making panels to cover these areas with Alclad Aluminum contributed by Air Parts Inc.
I used my Harbor Freight electric shear to cut it.Â Worked great!
One panel down, several to go!
Next I had to mark and drill rivet holes in the panels.Â I measured .5 inch from the edge then 1.5 inch spacing all around.
Ready to install panels.Â One problem.Â I only had enough rivets to install one panel!
The old black vent location.Â Should be leak free now!Â This was the only patch I had enough rivets to install.Â Need to fire my inventory guy.
Anyone got a rivet shaver for rent?!?!
Since I ran out of rivets, I went on to a different project alltogether.Â I needed to change out the trailers 6-pin wiring socket.Â The old one was rusted up.Â I also wanted to modernize it by adding a battery charge line, andÂ get connections for a power hitch jack and the emergentcy breakaway switch.
Here is the original rusted 6-way socket that was on the trailer.Â Notice the poor attempt to paint it to make it *pass* 😉
The left hole held the 6-way socket.Â The right one is a 4-pin socket.Â This is how the trailer was originally.Â When the cable was setup it would tie into both sockets.Â The 6-pin for brakes, running lights, brake lights, etc…, the right 4-pin was for a charge circuit only.Â So your cable coming from your tow vehicle had to split into two connections at the trailer end if you wanted to charge a trailer battery.
I re-wired the original 6-way socket, with a modern 7-way,Â to supply charging power as well.Â The 7-way socket adds a center pin which is normaly used for backup lights.Â Back-up lights are not available on my Ambassador. :-(Â In addtion to wiring the new socket, I routed, out of the belly pan, a power wire for a future jack, and the brake wire for a new brake away switch that I ordered from Vintage Trailer Supply.
Close up of new 7-way socket.
Job done!.Â With the rewiring I did, I will only need to use the 7-way socket for everything I need.Â The right 4-pin socket will now be available for an alternate charging plug, like from a generator,Â or a 12vdc power point to power 12vdc stuff outside the trailer.
