I think you will find that a short occurs as you change the point as the contacts switch the frog polarity, I seem to remember this has been discissed on on of the forums before and you need to cut the wires unde the point and add a switch to change the point direction and polarity at the same time.

Its also a good idea to put in insulated joiners to both rails and then wire the siding into the main bus, thus making it all part of the layout.

You do not say if the points are insulfrog or live frog so I think they are live frogs to get this problem.
