Can this tach be used on a BBC with a Vertex OXC Magneto?

Asked by: Willys41
You would need to acquire the 9118. Technically everything should work, but we would recommend the 6851 for optimal performance for you Magento.

How do you set the shift light?

Asked by: chili
Hi Chili, our different tachometers vary with how the shift point is set, but this specific model 233906 would follow this procedure: 1. Press both buttons at the same time while in the Normal Operation mode to initiate the Shift Light Set mode. 2. The Shift Light Set mode may be identified by the shift light flashing on briefly twice per second. The pointer will display the current shift light set point. 3. Press and hold the top button to scan upwards (clockwise). Press and hold the bottom button to scan downward (counter-clockwise). 4. A brief tap on either button will cause the pointer to move slightly in the appropriate direction for fine tuning the shift point. The gauge will return to Normal Operation by simply not touching either switch for 5 seconds.
