Unruly Generator!

[Johnny M Slone]

Hello to all,
On a recent outing with some fellow RVers we traveled to campground
during a heavy rainstorm. I arrived at the campground with no problem
that I could tell. Did all the things that we do when planning on
staying a couple of days. We enjoyed the evening with other BB owners
that were there. At about midnight I went to the bus for a nap. At
about 2AM I felt something shake the bus and then I hear this awful
noise of a diesel engine starting up. I think to myself, why would
someone start a noisy engine at this hour of the night. I get up to
see who has done such a thing and find out that it is my generator
that is running. I run to the front to push the stop button. The
engine stops running but the starter begins cranking trying to
restart it. The engine will not restart but the starter just
continues to try. I go outside and remove the cables from the gen
start battery. This has no effect, so I go back and remove the cables
from the house batterys. Still the starter is trying to restart the
engine. Finally I go around and throw the circut breaker off on the
AC power. All is silent now so I go back to bed.

The next morning I try turning the AC back on but the starter begins
cranking again. My friend and I finally managed to get the generator
to run out and removed the leads to the starter to disable it. A
couple of days later I put everything back and all is well. I have
looked the control circut over and can see no problems.

I have two questions, what could have caused this to happen and is it
normal for the house batterys to crank the engine after the generator
battery has been disconnected.

I did wire a relay in the control circut power lead so if this
happens again I can disable the crank and run circut with a toggle
switch.
