Heisler service diagrams

[badlydrawnroy]

I have aquired a second hand Heisler with lots of wires detached from the pcb : Does anyone have a service sheet with a wiring diagram? I want to convert it to r/c battery so I guess it will be the DC diagram I need.  Also, does anyone know how to dismantle the front truck for service?  
My usual source of such information, the bachmanntrains.com website, is strangely lacking in Heisler diagrams but they must exist somewhere!
