Re: (ET) E12 Stuck in Reverse/B145 traction motor overheating

[RJ Kanary <rjkanary nauticom net>]

The contactors are those big metal things mounted inside the control cabinet that go 'THUNK' when they are energized.

Do you have a Homeowner's Service Manual ? If not, get one. Don't venture inside your ET without one. :)

CZ,
Are the push-pull contactors the switches in the speed controller?  Any 
ideas on the best way to test them?

Two Issues:
My E12 was getting stuck in reverse and the machine needed to be shut 
off to correct the problem.  This happened twice then arcing/sparking 
sounds came from the electronics under the steering wheel and now the 
machine has no forward or reverse.  Any thoughts on what to 
troubleshot first?  I have an E12M I could swap parts off.
      

The E12 has the push-pull contactors, I wonder if the linkages broke 
on one of them and they shorted out cold?

That would cause major fun from the steering wheel part. Pull the 
panels and check the contactors.

My B145 seems under powered and the traction motor heats up and shuts 
off after about 15 minutes of use.  The brakes not stuck on and it 
has fresh gear oil.  Do I need a new motor?
Thanks for any insights,
