Subject: Connecting a 2nd battery & fridge questions
Would appreciate any comments on the following electrical and
fridge questions.
Last year, I purchased a '91 camper in which the previous owner had
already installed a 2nd battery. This last week (during a warm spell)
I installed a Propex heater (thanks much to Tom Forhan for his
how-to-install postings). When I looked at the van's 2nd battery
setup, it differed from the setup as indicated on the FAQ about "How do
I connect a 2nd battery?" The FAQ said to:
1. Disconnect your primary battery at the ground strap.
2. Disconnect the 2 red wires leading from the fuse box behind the
drivers seat from the relay terminals.
These wires lead to your fridge and cabin light.
3. Connect these two wires to the + terminal on the aux battery.
4. Run an 8 or 10 ga wire from the + terminal on the aux battery to
terminal #30 on the relay. This terminal supplies current to
charge the aux battery when the van is running.
5. Connect a ground strap to the aux battery.
6. Reconnect the ground strap on the primary battery.
The previous owner did not perform steps 2 and 3. He left the 2 red
wires connected to the silver relay switch. My guess is that in this
setup, the fridge, water pump, and control panel would all draw power
from both the 1st and 2nd battery and could run both batteries down
leaving me stranded if I forgot to turn something off. Is my thinking
correct on this or was the setup such that the 2nd battery wasn't
powering anything?
Under the recommended setup, it appears that the fridge, water pump,
etc would draw power from only the 2nd battery until it ran down.. Is
this correct?
While I had the fridge out to install copper tubing for the Propex, I
took Harry Yates advice and checked for rust and thankfully, found
none. In looking in the archives, I found Derek Drew's postings from
1994 about the wisdom of installing a small fan in the fridge to
circulate air over the cooling fins to increase overall cooling. He
installed a matchbook size fan from Radio Shack (they still sell it)
over the cooling fins and connected it to an external switch so he
could manually turn the fan on and off. I have the same problem with
inadequate cooling and am considering installing the fan in the fridge.
However, I was wondering if anyone had connected the fan directly to
a terminal on the fridge so the fan would automatically come on anytime
the fridge was running on AC, DC, or propane? If I could do that, I
would never have to worry about accidently leaving the fan running when
I didn't have the fridge turned on. If this is feasible, to which
terminal would I connect the fan?
While the fridge lights everytime I put it on propane, I had never been
able to take the cap off the drainage tube until I had the fridge out
of the van. The postings refer to blowing air in the tube if you ever
have trouble lighting the fridge. Thought I would check this out, and to
my disappointment, I can not manually blow any air through the tube. It
appears to be blocked. I don't have a local fridge dealer, but could
probably find one within a 100 miles. Should I try to find a dealer to
check the fridge, so should I leave well enough alone since the fridge
lights easily?
Thanks for any advice
