I found a great thread here about the grease freezing up on the old Williams engines. That's what happened to a SD45-10 Diesel that somebody gave me earlier in the year. I just got around to testing it and it would light up, but no movement. Before I fried anything, i searched here and found that the trucks can get stuck with the old grease. I took it apart, and that was the case. The wheels all move freely now and the engine moves as it should.
Two issues came up though -
I am using a Pure Power MRC controller and the horn does not work on the engine. The lights dim, but no horn. i am wonder how easy of a fix that is?
Also, one motor and truck would freeze occasionally when doing test drives. I took it apart, lubed it again, and it happened again. Then realized that the motor is getting stuck. I rotated the black spinning disk on the top of the motor, a small click would happen and it would unfreeze, and it worked. I had to do that twice and now it seems like everything is OK after several more test drives. If there is an issue there or a potential fix, please let me know?
** Edit - I put the body back on the train and the motor got stuck again.
Thanks in advance.
