I would like to figure out how to add an electronic tach (#0134-999) to a 78 Cheetah with a 500F/C motor. I did search the forum and I know that this engine should use a mechanical tach because the tach I have was designed to be used on a motor with fewer poles. However, has anyone tried to configure an electronic tach to work? I have seen tach’s (for boats) that allow you to “set” the number of poles on the back so the pulses are read correctly. I know the Arctic Cat tach doesn’t have that option but has anyone tried an inline resistor or other electrical means to prevent the tach from reading too high (reads 7,000 RPM at idle)? I’m not an electrical genius but if anyone can point me where to start, I’m willing to experiment to try and make it work. Any suggestions would be appreciated. Thanks, Rick
