Re: tach question

Outboard tachometers usually work by counting Stator pulses. There are usually settings for different stators, used on different motors. Why not find a new tach listing for your motor and see what the pulse count is and then renew your e-Bay search.

Re: tach question

Tachs actually count the poles in the flywheel. On your mtr you should set the tach to 5 P position.
