Default Induction Tach Help
Hey Guys...

I have a cheap induction tach for checking my idle after a carb rebuild, but I am not sure if I have to wrap the induction wire round the coil input wires or can get away with wrapping round the spark plug?

Did a little search but nothing on hooking one up...

Not sure if I'm missing something, just try it? Either works or it doesn't

You can get a reading by wrapping round the single spark plug lead, but I am not sure if the reading will be right...?

Haven't tried the coil yet as the input wires are tucked out of the way on the Road King...

I have no experience with your question but maybe just try it? If you don't get a signal then you'll know? Surprised nobody else has any input, somebody must have experience with this issue. Sometimes it takes a while

What's the instructions for the tach say? If you don't have the instructions do a search for instructions for the unit you have.

I have one of these. The response time is slow. Wrap around one spark plug wire.
