do you know for same dACi-TA 24/150 GB
what is AL 17 ?
if it were brushes it would be giving a different code most likely.
Bad com? maybe but that also would be giving a different code.
There are a couple of things to look for on the motor to determine if it has a thermal sensor on it, look for 2 wires connecting to a sensor connector somewhere near the middle or pump end of the motor housing. If you don't see one there then it may be mounted outside on the housing. If you still don't see one then maybe it is a sensor in the motor compartment near the motor.
If you dont see any extra wires other than the main cables then the problem may be in the motor controller giving you an overheat code for it. Usually the controller overheat code and the motor overheat codes are different though. This one did say motor temp overheat though.
thanks for your help
could it be brushes or bad com
has it got a thermal temp sensor on drive motor?
ok i was thinking that but had to be sure
AL90 has to do with traction motor temp too high if i'm not mistaken
i'll do more checking but thats what i come up with
thanks for your reply
