[VAC] Re: 3-way refridgerator - charging system

["Weimers" <mweimer@xxxxxxxx>]

I disconected my trailer battery while the car was plugged in (to the
trailer). My interior (trailer) lights still worked, so I assumed I had
power coming in from the car.  When I disconnected the trailer battery, I
made sure that the disconnected wire didn't hit anything, since I believe it
was off the positive terminal (which was closest to reach).  Then I used a
volt meter to see if I had charging power. Without the engine running, the
voltage should be 12 volt. With the engine running, it should be 13.5 volts.
I never saw this much voltage at the trailer battery, however. It seems to
charge anyway. (It must do it pretty slowly).

I also mounted a second battery in the tow vehicle so my trailer wouldn't
drain out the battery I use to start the engine. This system has worked well
for me over the years. I think I would do better if I put a larger gauge
wire in the charging line from the car, however.

I use a sissors jack on my '71 Globe Trotter (single axle). My car uses an
old fashioned bumper jack, so obviously, the car jack won't work for me! I
have ST225x15(load range D) radial tires on the GTand I find they are very
difficult to remove from the trailer. Actually, they are harder to get back
on. I found that I can get the tire on easier if I drain all the air out of
it. So I carry an electric tire pump too. The original equipment bias ply
tires were a tight fit also, but not as bad as the radials. Better try this
at home so you don't wind up doing it for the first time while on the road!
(I have never had a flat tire on the road). While you're at it you can check
the brakes and the bearings (I discovered that I  had to replace one of my
bearings this year).
