I have a Burlington Route 5601 that the headlight illuminates but the unit will not run. I'm not sure how old this unit is, I picked it up in the late 70s or early 80s. The number stamped on the side of the chassis is 81922. This unit also has an active tender. I have 14.7 volts DC coming from the truck to the side rail of the frame but no voltage to the motor pick-ups. I'm trying to remove the motor but There are no diagrams on the web site that show a similar motor or chassis set-up. 

Any suggestions? this unit was/is in too good of shape to just scrap
