I have a sunpro 5'' tach and ever since i have hooked it up it is jumpy so i put a resistor in i think .5-1 ohm helped it out a bit til after 5k then jumpy again. my question is should i just use a bigger resistor or do the mod of using diodes to make a four cylender signal for my tach. with two coil signal wires?
