Reply to "Rev I tiu voltage issue."

This sounds a lot like blown variable channel FETs.  I blew the FETs on both of my variable channels due to derailments.  I replaced the FETs on one channel and it works fine.  I will eventually get to the other one.  I am not sure which TIU revisions are prone to this problem.  The symptom I had was voltage passing through at a constant level.  The red button on the remote did not shut off the power to the channels with the blown FETs.  There are a number of posts on the FET problem.
