We have a 3 wheel hyster electric showing code 209L at start up. brake is new and the strange thing is that after start up if you unplug fuse #14 which is wire 10 into C3 position in controller and immediately plug fuse back in, truck will run all day until you shut off key switch. We have installed 2 different r/b controllers from flight systems as well as local dealer has let us take a controller from their shop out of a known running truck and all 3 have same issue and results. Zapi controller #FZ5017C ser #539443 417-2
Dealer tech as well as our techs have spent days on this truck and all leads to being controller issue, but I find that hard to believe with 3 different units installed
