For sale is a NEW, Hyster Forklift Keytroller Shock Memory Module 13902. What you see is what you get. I got this from a Hyster forklift parts dealer in a large box with many other things. Sometimes things fall out or get mixed together. This looks new to me. However, I cannot test this unit or verify its condition or tell what parts are or are not there. If you get it and it's not working, you can send it back for a refund. You would just pay all shipping. Please look at the picture carefully. Nothing else is included except what is in the picture. Thank you.
