Hi everyone,
I ran into a bit of a problem while driving in my Bobcat S70 (Aw6 2010 series), it shut completely off, while driving down a hill, with a full bucket of gravel which caused to parking brake to engage. The end result was that the parking brake "assploded!!!" (I had to pick out pieces of brake disk and metal shavings from the bottom of the lubrication pan). I replaced the entire parking brake system (disks, solenoid etc) then started troubleshooting why it shut down in the first place. I found that the 25A ENGINE (F11 slot) fuse was blown. I replaced that fuse and the bobcat will now turn on but it will not start -- i.e. wont crank. Now this S70 doesn't have any safety equipment that would stop it from starting -- the safety equipment just disables the hydro. All dash lights on the bobcat indicate that the computer detects no problems. I replaced the starter earlier in the year along with all the axels and bearings, I have replaced all the fuses and magnet relays in the skid steer. The Bobcat information system isn't producing any error codes when the cat is turned to the ON/RUN position (all fans turn on, full pump turns on, the correct lights are illuminated, etc) just turning the key from ON to START wont produce a crank. Battery is new and fully charged. I've checked the battery connections and ground connections that I could find and they are all solid. I replaced the key-switch in case it had a dead spot as well.
Here is a confusing thing. If i turn the key from the full OFF to START, as fast as i can bypassing stopping at the ON position, the engine will turn over but only for a fraction of a second then nothing. I can't see any frayed wires and I have cleaned and checked all the connectors (I can get to) for damage, oxidation etc. The only different thing I see is the BICS black box has a flashing green LED on it (which may be normal I've just never noticed it). I would like some advice on how to narrow down this problem as my only option now seems to load the parts cannon with everything electrical and fire it at the bobcat from point blank range -- I have NO experience with diagnosing electrical problems so I don't really know where to start. I have the bobcat service manual, parts manual and operations manual but you could fill a swimming pool with the amount of information NOT in those manuals. Thanks in advance.
