Hi Speedo,

you will find information when searching this forum with the following terms :tachometer intermediate unit
Basically the "intermediate unit" is a coil running in parallel with the points, when the points are closed, the coil charges up, and when the points open, it discharges into the tacho input lead.

thanks in advance for helping.
