circuit breaker trips on a line containing fan and light


Originally I had to replace a light switch in a box that also contained the switch for the fan. After repair everything worked normally, then one day I turned one of the switches on(I don't remember which one) and the circuit breaker tripped. Playing with it a little, I noticed that it didn't matter if the switches were off or on, it still tripped. I took the wires off both switches and tried the circuit breaker again. It stayed connected. There are two wires coming into the box that the top of the switches connect to. a green one and a red one I believe, although I cant recall for sure now. A black wire connected both switches at the bottom. While the CB was connected I Checked the voltage across each wire to ground. The light switch wire red 122 volts, which was in the ball park but the voltage across the fan wire only read 97 volts. Is this normal for the fan? Is it because maybe the fan is set on one of three speeds and is not turned off at the fan? My career was in Aviation Electronics not residential wiring, so I'm not sure what the light/fan situation is or how it is wired. At present, I just disconnected the fan completely, and use just the light but I would like to get it corrected.
Thanks,
Paul

you may a have switch leg and a feed mixed up here...you need to identify all the wires....most likely there is just 1 feed(maybe) and switch leg was dropped into this box...this is just 1 case.
