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

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.CZMy 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, Patrick McCabe _______________________________________________ Elec-trak mailing list Elec-trak cosmos phy tufts edu https://cosmos.phy.tufts.edu/mailman/listinfo/elec-trak
