In our case, for low rpms, we may need to use a motorcycle tach that reads
to 10,000 rpm and put ten studs, thus all we need to do is remove one zero.
You can pick up all the parts for this in any automotive junk shop.

We will probably end up with several of these and see which works best.

Most modern diesels and some truck engines  use a pickup coil  mounted close
to the flywheel.
The tachometer is programmable and counts the number of teeth on the ring
gear then divides the pulses by the correct factor to get RPM.  This is s
very accurate method suitable to very slow speed diesels.

Aetna makea very good tachometer package at a reasonable price.
