thanks, We have that optimizer what a pain in the @ss. We bought the tb44 new and it was still plugged into the port! The 110 uses this as well. Alexander equipment in Chicago has them. Have you had to get parts for these machines lately. They are getting to be a expensive as Grove lifts. Plus nobody at Genie wants to deal with you on the terex lifts. We replaced the boom cable in the 110 footer (bird nested inside the boom and trashed the cable) ended up getting it from Cetex because Genie couldnt even find the part we wanted.
