For sale is a Crown Sevcon Controller MOS 90. No. 129322. Part 631/41066. MOS90C. It comes from a parts inventory of a bankrupt Hyster dealer. It looks like it is in working condition, but I am not 100% sure about it. If you get it and it's not working, you can send it back for a refund of your bid. You would just pay the shipping both ways.
