I hope to resurrect this old thread because I’m desperately searching for something to fix this problem in my 2015 svl 75-2. Weather makes no difference; it’s been doing it for the last 4 months and I’ve gotten to work it very little during that time. It’s been in the shop at two different dealers for weeks at a time, have replaced the hydraulic lock switch (the green one), the armrest switches, the operator presence switch, and various wiring. Spent gobs of money on dealer repairs and renting a Cat to do my work. Last week dealer called and said replacing the operator presence switch didn’t fix it but he thought that since it’s two wires to that switch, and not three wires, that he could bypass it. I told him do it by all means. They called and said it’s ready to pick up. I drive up there with my trailer, and nothing has changed. It still won’t unlock. Various dealers, not just the two I’ve had it in, have various suggestions they pull out of the sky. One shop foreman on the phone said it doesn’t even have an operator seat switch (it does) and the the engine coupler to the pump is sheared off. Of course he is nuts, because the machine works fine on the rare occasion that it decides it will unlock today.
Please give me something to go on or send contact info of a good insurance arsonist.
