Interesting find.

- Description

This item has been discontinued from the manufacturer. If you want to make programming changes to your Gen4 you can use the [pc based](https://www.thunderstruck-ev.com/sevcon-gen4-pc-based-programming-kit.html) programming kit or you can rent one.

Hand Held Programmer for Sevcon Gen4 Controllers. Not all parameters available in the PC based software are available on the handheld unit. Because of this, the handheld is better suited for fine tuning an existing setup, but not for matching a controller to a different motor than it was originally programmed for.

All handheld programmers available for rental - 1 week for $50

Part# 662/14050

I found a source for new S4 350a controllers.  
Tell Mike if you want new. Add $350 and I’ll send one to him for programming.  
Or he may have a couple himself. Either way is fine.

ps.  
And another $350 for S6 550a ($700 upcharge)
