I have been in the process of attaching a tach to my motor. I haven't bee able to get a legible reading on the multi-meter. When I touch the ground/black lead (only) to the ground on the motor gives an un-readible readout. It almost looks like it jumps around based on engine pulses, but this is with ONLY the negative lead touching on the meter. Anybody have thoughts or experience with this?
