I need a wiring schematic for a 4905A GM the bus I am working on has tons of unused hanging wire I need to clean up.
I have most figured out but the neutral start is giving me fits

thanks

Any GM's I've worked on use the following:
-neutral start switch in the automatic tranny near the shift selector or a standard has a switch on the clutch pedal. There is also a normally closed switch in the fuel system which goes to ground for starting. It opens on running to prevent starting motor from engaging while engine is running. This is connectted to the start relay.

CLifford,

I just sent you a couple of scans: Engine Control and Coach Lighting. Hopefully they will tell you what you need to know. Let me know if you need anything else.

Bob
