- Wisconsin HET -

Applies to CDI equipped TRA12D, S12D and S14D Engines

This HET (Hall-Effect-Trigger) Module was designed to completely replace the OEM CDI Ignition System. The OEM CDI system is largely obsolete, other than the replacement OS69 (YB69) ignition module that we have built since it became obsolete is 2002.

Installation could not be any easier. Simply mount the module under the flywheel, route and connect two wires to the coil, apply 12V and turn the key.

Brett Clemmons who was the first HET customer, proudly stands by his restored 1477.

Attached is a picture of our tractor and its happy restorer. My father has made quick work of tilling our gardens with it this spring. I'm happy to report that it's still running strong, thanks to your wonderful ignition module, Dale. ...thank you again for the excellent product and extraordinary support. Count me among your grateful customers.

The HET is supplied complete with a Hi-Performance Bosch Blue ignition coil.  The introductory price of this system is $109.00, and includes Priority Mail shipping within the USA.
