Hi, I have lost my Speed and I think it is the speed sensor pickup. I found that the sensor worked loose and the end has some damage. If the end of the pick up hit the wheel would that be the cause? If it is the sensor where can I get a replacement? The system in my car is an old Stack. Thanks Joel

The most common cause of a failed sensor is when the sensor end hits the target (or finds a rock between the sensor and the target).

Veracity Racing Data can provide either the original Stack ST670 sensor:

Or a lower-cost equivalentL

Thanks, will give you, Veracity a call. If the only difference is I have to cut and add the plug to the less expensive one, that works for me. Joel
