My main question is about how the GP circuit works.
I am afraid I have a freak setup, with newer components in an older frame. Mine in the tractor is a five wire, and has as far as I can tell, an additional position for the ACC.
The information there in the manual, as well as any I can find on the internet shows a four wire switch. All the diagrams and pictures show a different location for the glow relay as well as other relays too.
I have a factory service manual that outlines the wiring and a few descriptions of the circuit but it is inaccurate for my specific tractor. I am having trouble finding the fault in my glow plug circuit for a M9000.
