I was looking at an '87 camper today, and I'm wondering how the proper
operation of the fridge can be tested.  There's no propane, but I'd like
to check it on 110 and 12V.

Since there's no time to  let it cool, all I can do is see the light come
on indicating 12V operation.  Should I be hearing any sound at all?

Also, I tried hooking up city water, and once the hose was turned on to
let water into the outlet on the side of the vanagon, the water pump
sound was continuous whether or not the knob was turned to let water come
out.  This doesn't seem normal, and when the city water was disconnected,
the pump would only make a sound when the knob was turned to the
direction to access the water tank.   Any thoughts about this?

As much as I've learned over the last couple of years about the
mechanical aspects of vanagons, the camper features are still new to me.

Thanks in advance for any insight.
