Wiring Tach

[flipscobra]

If some of you have a Smith Tach how did you hook up your MSD ignition. I plugged my tach to the MSD box an it works fine till it hits about 3000 rpm's then it falls back to 0, has anyone else had this problem. Do I need an adapter if so which 1. Thanks Flip

It seems that you might need a tach adapter, call MSD they will help you out as to what you need exactly, I had similar problem when I installed my msd and they were great.
