Acewell Speedometers Frequently Asked Questions
Q: How far away does the magnet need to be from the sensor?
Q: Why does my speed double after 10mph?
A: The speed only doubles on Acewell’s if the two lines on the sensor are not positioned vertically.
Q: How do I install the tachometer wire?
A: Wrap the yellow wire that’s been included with your Acewell around the ignition coil 3-5 times. Make sure the spacing between each wrap is equally spaced and there isn’t a gap between the ignition coil and the yellow wire.
Q: How do I install the tachometer wire on a coil pack?
A: If your street bike uses a coil pack, you need to find the appropriate size resistor that will go inline between the tachometer wire and your coils power wire.
Q: Why is my tachometer reading erratic?
A: If your tachometer reading is erratic, the spacing between each individual wrap needs to be increased/decreased and you need to double check the gap between the ignition coil and yellow wire.
