Hi, I have a newish 70 ton 3 truck climax. It has less than 2 hours runtime. It suddenly stopped running. Motor not running... I have heard of the split gear problems and so trying to track it down. I have actually disconnected all 3 trucks from the main gearbox to see if the motor will run. The rods and pistons on the sides will run about 1/2 second and then seize up and not run. I removed the decoder and jumpered a 3 volt battery pack to the motor pins on the 8 pin socket. It will run for a while and seize up. Again, this is with no trucks or their associated gearing connected. So its just the motor to the siderods.  I began to think there might be an issue with the circuit board - newer style with mostly smd electronics. So I cut out the board and soldered in an 8 pin socket to eleminate board issues. This did not change anything. So I am now at a loss of what is next. Motor? Is there a capacitor directly on the motor itself that should be cut out? Is it possibly gearing in the main gearbox? How should I proceed and is the motor easy to get to without complete dis-assembly of all the bits and pieces?
Please help. Thank you.
