Light switch troubles.

| So, I installed a new fan,one that controlls dimming and fan functions
from a stand-alone switch that you can mount to your wall and that
doesnt require wires and is battery operated. I had to undo a set of
wires that served the same purpose of turning both the light and fan
off and on so I could attach the dimmer controller in the old switches
place. My problem occurs when I turn on the hallway light, which is on
the same curcuit as the fan. It trips the CB, (rated at 15 amps). It
never did this with the old fan, so I am beginning to think that maybe
my wires are wrong. First, I noticed there is no ground wires going to
the other light switches near the new dimmer switch. Could that have
anything to do with it? Second, could it be a resistence issue? I have
a multimeter, but I suspect I would have to create the worlds biggest
jumper to measure the resistence in the wire, and I would still need
to know how much is acceptable. Any help or expertise would be greatly
appreciated.

It sounds to me like you might have a 3 way switch in the hall. check to see
(with the breaker off) if it has 2 or 3 wires going to it. If it is
miswired, then yes you are shorting the circuit when you flip the switch.
