Thanks.  At the same auction I bought a 1664 with tender.  It was in very bad shape.  Motor was locked up and had rust issues.  I really just wanted it for parts out of the tender.  The engine looks good so I decided to tear into it.  The e-unit is definitely shot.  I got the motor cleaned up and was trying to bypass the e-unit just to see if I could get the motor to work but so far no success.  Should I be able to bypass the e-unit to make the motor run?  If so but it’s not working any thoughts on why I can’t get any response from the motor?

I bought a Rio Grande 8454 at an auction last weekend.  It makes a rather loud buzzing noise when I run it.  I don't know the name of the parts very well but would say it is the e-unit.  The noise is not coming from the motor.  Any thoughts on what is causing the noise and how it can be fixed?
