God,I love my job.
Over the weekend,had a TMS 500 go down.
The guy troubleshooting it found a bad scr,replaced it.
Trying to run the car on inspect. the motor makes a loud rumbling noise,just barely moves and things start smoking.
I get there,there is a chainfall on top the car because the repair team thought maybe it was set on safeties.
They can't budge the car.
Waiting for me is a huge a-frame because they are going to replace the motor.
This has 5 connections to the motor,,u,v,and w 1 and 2.
I measure the voltage coming from each scr when we try to run it.
I get 109,79,109.
Waiting on a new contactor and new scr's.
Hoping that fixes it.
Could one of the fields be bad in the motor or a bad drive board?
