I had my alternator belt flip over at an autocross last weekend. Anyone else ever seen this?
Belt was on the fan and alternator pulleys, just as it should be, but the teeth were facing outward. It had flipped itself inside out! Tension was good. Adjuster bolt still tight. Discovered this after the motor had started cutting out and finally stopped on course. The cause for that was the electrical connections coming off of the starter motor. Those connections include the power supply to the CDI box. So the engine quit due to no spark. The nut had backed off and fell off. (User error on that. Could'a swore I'd torqued that nut...) My theory is that, as the electrical connection was shaking loose, the engine was cutting in and out, and the torque variations from that process caused the fan belt to jump around enough to flip over. But that's just my theory. Anyone else had any experience with a problem like this? Thanks, Andrew Blyholder |
