[QUOTE="MTMechanic22, post: 123673, member: 22680"] I got a bobcat 873f series here that I’ve been dealing with for sometime now. Originally it started with the entire brake system in a ton of pieces at the bottom of the chain case. After all was put back together with new parts I couldn’t get the solenoid to disengage the brake lock. I’ve been through just about every wire doing continuity checks, voltage checks etc. the traction lock light is not flashing since I repinned the bics plug. Also the bics is brand new out the box because I figured it would fix the issue. I’ve checked the boss and it’s connections. Finally I thought I had figured that the rpm sensor was the culprit since the bics needs to see a signal from that sensor. Replaced it and tested both old and new with a scope. They seem to be working fine but still no signal. I’ve checked for voltage and continuity between the sensor, bics and boss. I was reading a forum on this site saying the control module in the left frame can go bad. I just need to confirm my suspicions because at this point there is no other likely cause. If someone has dealt with this issue please help me out! [/QUOTE]
