My Kart tach reading is erratic. What can I do to fix it?
Most erratic kart tach readings are caused by ignition noise. Try separating sensors and keeping them away from the coil. Install the tach sensor one to two inches from the end of the plug boot and try a resistive plug boot (NGK part LB05EMH). If these suggestions do not help contact Digatron to discuss other tach sensor options.
