[QUOTE="Daveb68, post: 117991, member: 16779"] I read somewhere that if your not getting a constant 12 volts on your battery it could cause your brake system to lock up and that was about how long my S250 was running for before it also locked up the brakes. if it does happen and you really need to move it right away then throw a quick jump on the battery bringi it up to 12 volts and then figure out we’re your draw is coming from. I started by installing positive & negative new Bobcat factory terminals. The negative has two grounds, one to the steel panel underneath the engine right next to the battery & another ground that goes directly to the engine block. The positive goes from the terminal over to your solenoid & then directly to your starter. i recommend the top post terminals because all of the heavy gauge wiring comes right out of the sealed led terminals and everything is nice and tight like it was from the factory. If yours are good then leave them, maybe just take the bottom ground off & grind any rust or other unwanted debris off and re install then clean up any other crap that looks like it could use a cleaning and make sure all of the bolts & nuts are tightened up good. The new factory terminals with new wiring isn’t cheap so if you can avoid replacing them then do so and spend the money trouble shooting looking around for faulty wiring and give your fuse panel a good look through. I’ve seen corroded fuses snapped off and stuck in the panel so look for that & then make sure all the right size fuses are in the proper spot then look over your relays, you know all of the obvious stuff and hopefully that will solve your problem. It appears to be one of the more common issues I’ve seen in this forum. Oh, make sure you check your brake switch & that the red light inside the switch is on when brake is activated & also make sure when the machine is running & you disengage your brake switch that all four round lights on the Bics panel are lit up because depending on what those lights are doing when your brakes lock up can give you some hints as to what the problem could be too. Check all your wires under your seat when you lift up the cab are good especially the ones coming directly out of the back of your fuse panel. [/QUOTE]
