Bathroom Exhaust/Light fan wiring.

Hi, I am trying to replace an old light that was installed in our bathroom with a combination exhaust fan/light fixture. I have attached all the wiring (all blacks to blacks) (all whites to whites) when I have just (2) wires from the wall switch hanging out with nothing attached and turn on the circuit breaker, the light & fan goes on. But, when I attach the "switch" to the circuit, the breaker trips. What did I do wrong? Thanking you in advance for your immediate attention in this crazy matter, Bob

The wires from the wall switch are a switch loop and not designed to be all hooked to black and white. One was hooked to power,, white one (mark it with tape) Hook that one to the black power wire coming into the fixture box ,, hook the rest of the whites together and the black return from the switch to the black of the fixtures. You will have to run the fan with the light as there are not enough wires to do it seperatly.

Just make sure you know which black/white pair is the power cable and which is the switch loop. It would be dangerous to mix them up. If you need help sorting this out, just ask.
